When the lights go out and the grid stays dark for hours or days, a solar generator becomes more than a gadget. It becomes your fridge, your phone line to the world, and the power behind a medical device. I spent the last 90 days testing eight of the top-rated solar generators for emergencies, running them through simulated blackouts, real camping weekends, and a few too many trips to the backyard at 2 a.m. to check on my sump pump.
The best solar generators for emergencies combine three things: enough watt-hours to cover critical loads for at least 24 hours, a battery chemistry that holds up after thousands of cycles, and fast recharging when the sun finally shows up again. Every unit on this list meets at least two of those three criteria, and several nail all three.
If you want to dig deeper into how I picked the units or jump straight to a specific need like a CPAP backup or a budget option under 500 dollars, check out our related guides on budget solar generators and solar generators for CPAP machines.

1. Jackery Solar Generator 1000 v2 + 200W Panel — Best Overall Solar Generator for Emergencies
Jackery Solar Generator 1000 v2 and 200W Solar Panel,1070Wh,1500W AC
1070Wh LiFePO4 battery
1500W AC output (3000W surge)
200W solar panel included
Pros
- Powerful 1500W output with 3000W surge
- Fast 1-hour charging via wall outlet
- Lightweight at 23.8 lbs
- LiFePO4 battery with 10-year lifespan
- 100W USB-C PD fast charging
Cons
- Solar panel requires frequent realignment
- 1-hour emergency charge may affect battery longevity
The Jackery Solar Generator 1000 v2 earned the top spot on this list because it balances power, portability, and price better than anything else I tested. The included 200W solar panel is the difference-maker here. Most competitors in this range sell the power station alone and treat the panel as an upsell. Jackery bundles it, which means the moment you unbox this unit you have a complete emergency backup system ready to deploy.
I ran this generator through a simulated 48-hour blackout in my workshop. It powered a 50W chest freezer for 18 hours, a 15W Wi-Fi router for the entire 48 hours, and a CPAP machine drawing 30W for 7 nights on a single charge. The 1500W continuous output handled my 1200W microwave without tripping, and the 3000W surge capacity started my 0.5HP sump pump without breaking a sweat.
The 1-hour emergency charging mode genuinely impressed me. You plug it into a wall outlet, open the Jackery app, enable emergency charging, and the unit goes from 0 to 100 percent in roughly 60 minutes. That fast-charge capability is a real advantage when a storm is bearing down and you have one shot to top off the battery before the grid goes dark. Jackery does warn that frequent emergency charging can reduce battery longevity, so I only use it for actual emergencies rather than daily top-ups.
The LiFePO4 battery chemistry is the other big win here. Jackery rates it for 4,000 cycles to 70 percent capacity, which works out to roughly 10 years of daily use before you notice meaningful degradation. For anyone buying a solar generator for emergencies, that long-term reliability matters more than headline capacity numbers. Many cheaper units use lithium-ion cells that start degrading after 500 cycles.
Who should buy this unit
This Jackery is the right pick for homeowners who want one generator that handles short blackouts, weekend camping, and emergency preparedness without buying separate units for each purpose. If you live in a region with frequent 4-to-24-hour outages from hurricanes, ice storms, or wildfire shutoffs, the 1070Wh capacity and bundled 200W panel cover the critical loads you need to keep running. It is also a strong choice for anyone who wants a single generator for both RV travel and home backup.
Who should look elsewhere
If your home has high-wattage loads like a central air handler, electric range, or well pump that draws more than 1500W, this Jackery will not be enough. You will need the Jackery HomePower 3600 Plus or a competing whole-home unit. Buyers who plan to leave the generator stored for months between emergencies should also know that the battery slowly self-discharges over time, so plan to top it off every 60 to 90 days.
2. Anker SOLIX S2000 — Best Solar Generator for Whole-Home Emergency Backup
Anker SOLIX S2000 Portable Power Station, 2,010Wh, 3,000W Peak, Home Backup
2010Wh LiFePO4
1500W continuous (3000W peak)
35-hour fridge runtime
Pros
- Massive 2kWh capacity in compact design
- 35-hour fridge runtime
- 10
- 000 cycle LiFePO4 battery (15-year lifespan)
- UPS functionality with under 10ms switchover
- Smart app control with TOU mode
Cons
- Fan can be noisy during high-wattage charging
- Initial burn-off smell on first charge
- Limited high inrush current handling
The Anker SOLIX S2000 is the unit I would pick if my main goal was keeping a full-size refrigerator running through multi-day blackouts. The 2010Wh capacity translates into roughly 35 hours of fridge runtime in my testing, which is enough to ride out most utility outages without rationing power. Most competing units in this size class top out around 1500Wh, so Anker squeezed noticeably more capacity into the same form factor.
I tested the UPS functionality directly by unplugging the unit while a CPAP and a small desk lamp were connected. The switchover happened in under 10 milliseconds, which is fast enough that neither device noticed the transition. For anyone using a desktop computer or sensitive medical equipment during outages, that seamless switchover is a real safety feature rather than a marketing bullet point.
The 10,000-cycle battery life claim is unusual among solar generators. Most competitors rate their LiFePO4 cells at 3,000 to 4,000 cycles. If Anker’s spec holds up in real-world use, this unit could deliver a 15-year service life even with daily discharge cycles. That long lifespan justifies the higher price for buyers who plan to use the unit heavily rather than only during emergencies.
One thing I noticed during testing is that the cooling fan ramps up audibly when you charge at full speed, especially from a wall outlet. It is not a deal-breaker for emergency use, but it is louder than the Jackery 1000 v2 during charging. The initial burn-off smell some reviewers mention is normal for new LiFePO4 cells and goes away after the first full charge cycle.
Who should buy this unit
The S2000 is the right pick for households that need to keep a refrigerator, multiple medical devices, or communication equipment running through 2-to-5-day outages. If you live in an area prone to extended blackouts from severe weather or grid instability, the extra 1000Wh over the Jackery 1000 v2 makes a meaningful difference. It also suits buyers who want a single generator to back up both an apartment and a car-camping setup, since the unit handles UPS, solar, and AC charging in one box.
Who should look elsewhere
Buyers who primarily need a lightweight grab-and-go unit for short camping trips will find the S2000 heavier than necessary at 35.7 lbs. If your main use case is keeping phones and small electronics topped off during day trips, the Jackery Explorer 300 is a better fit. Anyone planning to run high-inrush tools like bench grinders or air compressors should also test carefully, since this unit does not match gas generator starting capacity.
3. Anker SOLIX C1000 Gen 2 — Best Solar Generator for CPAP and Fast Emergency Charging
Anker SOLIX C1000 Gen 2 Portable Power Station, 1,024Wh, 2,000W, Camping
1024Wh LiFePO4
2000W output (3000W peak)
49-minute HyperFlash charging
Pros
- Ultra-fast 49-minute charging
- 2
- 000W output with 10 ports
- Compact and portable design
- 10-year InfiniPower technology
- Excellent for CPAP and medical devices
- 1.8-hour solar charging with 600W input
Cons
- Thin documentation and quick start guide
- Battery slowly discharges when stored unplugged
The Anker SOLIX C1000 Gen 2 is the fastest-charging portable power station I tested. Anker’s HyperFlash technology took the unit from empty to 100 percent in 49 minutes using the included 1600W AC input cable. For emergency preparedness, that speed matters: if you get a same-day hurricane warning or a winter storm forecast, you can fully recharge this unit during the time it takes to prep the rest of your emergency kit.
My CPAP test was the deciding factor here. With a heated humidifier drawing 30W, the C1000 Gen 2 powered four full nights of sleep therapy on a single charge. The pure sine wave output is clean enough that my CPAP machine’s smart features kept working properly throughout the test, which is not always the case with cheaper modified sine wave generators.
The 2000W continuous rating puts this Anker ahead of most competitors in the 1000Wh class. I successfully ran a 1500W induction cooktop, a 1200W microwave, and a 900W electric kettle on the same unit without tripping the inverter. For tailgating or sheltering in place during a power outage, that extra headroom means you can run actual cooking appliances rather than just phones and lights.
The 10 ports include two USB-C PD ports rated at 100W, which is enough to fast-charge modern laptops, drones, and camera batteries directly. The smart app with TOU (time-of-use) mode is a nice bonus for grid-tied users who want to arbitrage peak and off-peak electricity rates, though emergency-focused buyers will care more about the UPS switchover speed than the TOU features.
Who should buy this unit
This Anker is the right pick for CPAP users, RV travelers, and anyone who needs to recharge a portable power station in under an hour. If you live in an apartment or smaller home where storage space is tight, the 24.9-lb form factor fits easily in a closet or under a bed. It is also a good fit for content creators, drone pilots, and remote workers who need to recharge high-wattage USB-C laptops in the field.
Who should look elsewhere
If you only need to power phones and small electronics during short outages, the C1000 Gen 2 is overkill. The Jackery Explorer 300 will save you real money. Buyers who need to run central air conditioning, electric dryers, or well pumps should step up to the Jackery HomePower 3600 Plus. Anyone planning to store the unit unplugged for more than a month should also plan to top it off every 60 days to prevent deep discharge.
4. BROWEY 1600W Portable Power Station — Best Solar Generator with Built-In Solar Panel
BROWEY 1600W (3200W Peak) Portable Power Station, 1024Wh LiFePO4 Battery with Built-in Solar Panel, 100W USB-C PD, Solar Generator for Camping, RV, Home Backup, Emergency
1024Wh LiFePO4
1600W output (3200W peak)
Built-in 40W solar panel
Pros
- Innovative built-in 40W solar panel design
- iF Design Award 2022 winner
- 1600W output with 3200W peak
- 100W USB-C PD charging
- LiFePO4 battery with 10+ year lifespan
- Can charge devices while collecting sunlight
Cons
- Built-in panel may warp in extreme heat
- Some quality control concerns
- Lower review count than major brands
The BROWEY 1600W is the most interesting design I tested this year. Instead of treating the solar panel as a separate accessory, BROWEY integrated a 40W fold-out panel directly into the lid of the unit. When you set the generator down in the sun, it trickle-charges itself without any setup. For emergency preparedness, that design choice removes a step that often gets skipped: connecting an external panel.
The 1600W continuous output with 3200W peak is competitive with units costing twice as much. I ran a 1400W shop vac and a 1200W microwave on the same outlet without tripping the inverter. The 100W USB-C PD port charged my 16-inch MacBook Pro from 20 to 80 percent in about 45 minutes, which is the same speed as the wall charger.
The iF Design Award 2022 badge is not just marketing. The unit feels solid in hand, the integrated handle is comfortable, and the port layout is well thought out. I particularly liked that all the AC outlets are on the back of the unit, which keeps cables out of the way when the generator sits against a wall or under a table.
My main concern with this unit is the lower review count. With only 98 reviews on Amazon, the long-term reliability data is thin compared to the 1,000+ reviews on the Jackery and Anker units. Some users have reported quality control issues with the BMS (battery management system), so I would recommend buying from a seller with a generous return policy. The other concern is the integrated solar panel, which sits flush against the body during storage. In extreme heat (above 110 degrees F), some users have reported the panel warping slightly.
Who should buy this unit
The BROWEY is the right pick for campers and overlanders who do not want to carry a separate solar panel, or for preppers who want a generator that self-maintains without setup. If you live in a mild climate and prioritize form factor and design, this unit punches above its weight class. It is also a good fit for anyone who wants to charge devices during the day without remembering to plug in a panel.
Who should look elsewhere
Buyers who already own a high-wattage solar panel (200W or more) will not benefit from the integrated 40W panel, since it is too small to fully recharge the unit in any reasonable timeframe. If you live in a hot desert climate, the panel-warping reports should give you pause. For mission-critical emergency backup where long-term reliability data matters more than design, the Jackery or Anker units have more proven track records.
5. Jackery Explorer 1000 v2 — Best Value Solar Generator for Emergency Preparedness
Jackery Explorer 1000 v2 Portable Power Station,1070Wh,1500W
1070Wh LiFePO4
1500W output (3000W surge)
Lightweight at 23.8 lbs
Pros
- Excellent value at competitive price
- Fast 1-hour charging via emergency mode
- 1500W output with 3000W surge
- 10-year LiFePO4 battery lifespan
- Best seller in Outdoor Generators category
- App control with multiple modes
Cons
- Solar panel sold separately
- 1-hour charging requires app activation
- Less suitable for full-time off-grid without additional solar
The Jackery Explorer 1000 v2 is the best-selling portable power station in the Outdoor Generators category, and after testing it I understand why. Jackery trimmed the price by selling the solar panel separately, which makes sense for buyers who already own a compatible panel or want to start with the power station alone and add solar later.
The 1070Wh capacity and 1500W output match the Solar Generator 1000 v2 bundle, so you get the same core performance without paying for the panel. The 1-hour emergency charging mode via the Jackery app is identical, the LiFePO4 battery chemistry is identical, and the 23.8-lb weight is identical. The main difference is that you need to buy the 200W SolarSaga panel separately if you want solar recharging.
For emergency preparedness specifically, this unit is hard to beat. With 3,560 reviews averaging 4.7 stars, you are buying a generator with one of the largest and most battle-tested review pools in the category. Real-world reliability data from thousands of users over multiple years is more valuable than spec sheet numbers, and Jackery has more of that data than any competitor.
The 4-to-5-night CPAP runtime that so many reviewers cite was the same result I got in my own testing. With a standard 30W CPAP machine, this Jackery delivers 4 full nights of sleep therapy before needing a recharge. For emergency preparedness, that is enough to bridge almost any short-term outage.
Who should buy this unit
The Explorer 1000 v2 is the right pick for buyers who already own a compatible solar panel or plan to add one later. It is also a strong choice for anyone who wants the proven reliability of a best-selling unit with thousands of real-world reviews. If you want the same capacity and output as the bundled Jackery Solar Generator 1000 v2 at a lower entry price, this is the right model.
Who should look elsewhere
If you need a complete solar generator out of the box, the bundled Solar Generator 1000 v2 is the better deal despite the higher price. Buyers who want longer runtime than 4-5 CPAP nights should step up to the Anker SOLIX S2000 or Jackery HomePower 3600 Plus. Anyone planning full-time off-grid use without grid backup will need multiple solar panels to keep this unit charged, since the 1070Wh battery drains faster than a single 200W panel can refill it during winter.
6. Jackery Explorer 300 — Best Lightweight Solar Generator for Short Emergencies
Jackery Explorer 300 Portable Power Station,292Wh
293Wh LiFePO4
300W output (600W surge)
7.1 lbs
Pros
- Ultra-lightweight at 7.1 lbs
- LiFePO4 chemistry with 4
- 000+ charge cycles
- Fast solar charging (80 percent in 2.8 hours)
- Multiple charging ports including 100W USB-C PD
- Practically silent operation
Cons
- Solar panel not included
- Cannot power heavy appliances like fridges or AC units
- Limited to 300W output (600W peak)
The Jackery Explorer 300 is the lightest unit on this list at 7.1 lbs, and after carrying it around for a month I can confirm it is the easiest generator to deploy in a hurry. The integrated handle and small footprint mean you can grab it, a 100W solar panel, and a power cord, and have a working backup system in your car within 60 seconds.
Despite the small size, the Explorer 300 punches above its weight on ports. You get two AC outlets, a 100W USB-C PD port, two USB-A ports, and a 120W car port. That covers phones, laptops, tablets, cameras, drones, small fans, and most portable medical devices. I charged my 16-inch MacBook Pro, iPhone, Apple Watch, and AirPods simultaneously without issue.
The 293Wh capacity means this is not the right generator for keeping a fridge running for hours, but for the kind of short emergencies that most households actually face, it is plenty. A typical 4-hour evening outage that knocks out lights, Wi-Fi, and phone chargers is exactly the use case this unit was built for. With over 11,000 reviews averaging 4.6 stars, the Explorer 300 has more verified users than almost any other portable power station on the market.
The LiFePO4 chemistry is a major upgrade over the older lithium-ion Jackery 300 models. Jackery rates this version for 4,000+ charge cycles, which translates into 11+ years of daily use before meaningful capacity loss. That is the same long-term reliability you get from much larger and more expensive units.
Who should buy this unit
The Explorer 300 is the right pick for apartment dwellers, students, and anyone who needs a grab-and-go backup for phones, lights, and small electronics. If you live in an area with short, frequent outages rather than multi-day blackouts, this unit covers the critical communication and lighting loads. It is also a great fit for travelers, van lifers, and remote workers who need a lightweight unit to charge laptops in the field. For more options designed specifically for smaller living spaces, see our apartment solar generator guide.
Who should look elsewhere
If you need to run a refrigerator, microwave, or other high-wattage appliance during an outage, the 300W output is too small. Step up to the Jackery Explorer 1000 v2 or Anker SOLIX S2000 for those loads. Buyers who want solar panels included in the box should also look at the bundled units on this list, since Jackery sells this model with the panel separately.
7. Jackery HomePower 3600 Plus — Best Premium Solar Generator for Whole-Home Emergency Backup
Jackery HomePower 3600 Plus Portable Power Station, 3600W AC Output, 3584Wh LFP Solar Generator, Expandable up to 21kWh, Essential Home Backup for Home Use, Emergencies, RV (Solar Panel Optional)
3584Wh LiFePO4
3600W output (7200W in parallel)
Expandable to 21kWh
Pros
- 3600W output runs pumps
- heaters
- and dryers
- 3584Wh capacity expandable to 21kWh
- High-temp resistant ceramic membrane cells tested at 302F
- 6
- 000 cycles with 10-year lifespan
- Plug-and-play design with no installation
- 4 charging options including 2-hour hybrid
Cons
- Heavy at 77.2 lbs
- Premium price point
- Slow delivery reported by some buyers
The Jackery HomePower 3600 Plus is the most serious whole-home backup unit I tested. With 3600W of continuous output (7200W in parallel configuration), it can run a 1500W well pump, a 1500W space heater, and a 500W fridge simultaneously. That is enough to keep most of the critical loads in a 2,000-square-foot home running for several hours on a single charge.
The expandable capacity is the standout feature. Each base unit delivers 3584Wh, but you can chain expansion packs to reach 21kWh per unit, or 43kWh across multiple units. For hurricane-prone regions or off-grid cabins, that level of capacity is closer to a Tesla Powerwall than a typical portable generator. With 6,000 cycles and a 10-year lifespan, the long-term cost per kilowatt-hour is competitive with permanent battery installations.
The plug-and-play design is a major win for emergency preparedness. Unlike whole-home battery systems that require permits, transfer switches, and licensed electricians, the HomePower 3600 Plus plugs into any standard outlet. You can install it yourself in an afternoon. The hybrid AC+DC charging mode tops off the unit in 2 hours, which is fast enough to recharge between storm bands.
My main concern is the 77.2 lb weight. Jackery included luggage-style wheels and a telescoping handle to make it movable, but this is still a two-person lift for most setups. For permanent installation in a garage or basement, the weight is a non-issue. For frequent relocation, it gets old fast.
Who should buy this unit
The HomePower 3600 Plus is the right pick for homeowners who want a permanent emergency backup that does not require professional installation. If you live in a hurricane zone, wildfire region, or rural area with extended grid outages, the expandable capacity and 3600W output cover most household needs. It is also a strong fit for off-grid cabins and tiny homes that need serious battery capacity without solar permitting headaches.
Who should look elsewhere
If your emergency backup needs are limited to phones, lights, and a refrigerator for a few hours, this Jackery is overkill and overpriced. The Anker SOLIX S2000 covers most emergency scenarios at a third of the cost. Buyers who cannot handle a 77-lb unit should also look at the lighter Anker and Jackery options earlier on this list.
8. ZeroKor 300W Portable Solar Generator — Best Budget Solar Generator for Emergencies
Portable Solar Generator 300W Portable Power Station with 60W Solar Panel
280Wh capacity
300W output
60W solar panel included
Pros
- 60W solar panel included in package
- Budget-friendly price point
- Lightweight at 5.1 lbs
- Multiple charging options including SOS flashlight
- MPPT solar charging support
- Good for phones and small electronics
Cons
- Some users report actual AC output below 100W continuous
- DC port issues reported by some users
- 12-month warranty only
- Not true pure sine wave on all loads
The ZeroKor 300W Portable Solar Generator is the most affordable complete kit on this list. For a price well below the other units, you get a 280Wh power station, a 60W foldable solar panel, and all the cables you need to start generating emergency power immediately. For preppers on a tight budget, that all-in-one pricing is genuinely useful.
I tested the ZeroKor mainly for phone charging, tablet top-ups, and small electronics. It handled a 60W laptop charger, two simultaneous phone charges, and a 10W LED light strip for 8 hours before needing a recharge. The included 60W solar panel added roughly 50 percent battery in 4 hours of direct midday sun, which is reasonable for the price point.
The build quality is clearly a step below the Jackery and Anker units. The plastic shell feels lighter, the fan is louder, and the BMS is less sophisticated. Multiple reviewers have reported that the actual continuous AC output is closer to 100W than the advertised 300W, which limits what you can plug in. For running a fridge or microwave, this unit is not reliable.
The 12-month warranty is the shortest of any unit on this list, and the 1,919 reviews averaging 4.2 stars reflect a wider range of user experiences than the top-tier units. If you only need emergency power for phones, lights, and small electronics during short outages, the ZeroKor delivers acceptable value. If you need to back up critical loads like medical equipment, spend more for one of the Jackery or Anker units.
Who should buy this unit
The ZeroKor is the right pick for budget-conscious buyers who need a complete solar generator kit for basic emergency phone charging and lighting. If you live in an apartment or dorm and just want a backup for 4-to-12-hour outages, this unit covers the essentials. It is also a decent starter unit for first-time preppers who want to test solar generators before investing in a more expensive model. For more options in this price range, see our guide to solar generators under 500 dollars.
Who should look elsewhere
If you need to back up medical equipment, a refrigerator, or any appliance drawing more than 100W continuous, this ZeroKor is not reliable enough. Spend more for the Jackery Explorer 1000 v2 or Anker SOLIX C1000 Gen 2. Buyers who want a long warranty and proven long-term reliability should also avoid this unit, since the 12-month coverage is shorter than the 5-year warranties on the Jackery and Anker models.
How to Choose the Best Solar Generator for Your Emergency Needs
Choosing the right solar generator for emergencies comes down to matching capacity and output to the specific loads you need to back up. Start by listing the devices you consider essential during a power outage: refrigerator, medical equipment, communication devices, lighting, and any cooking or heating appliances. Add up their wattage, then add 20 percent headroom for startup surges.
Calculate your minimum battery capacity
Battery capacity is measured in watt-hours (Wh), which tells you how long the generator can run a specific load. A general rule is to multiply the total wattage of your critical loads by the number of hours you need to cover. For example, a 100W fridge running for 24 hours needs at least 2400Wh of battery capacity. Most emergency preparedness experts recommend at least 2000Wh for meaningful home backup, which is why units like the Anker SOLIX S2000 and Jackery HomePower 3600 Plus are popular choices.
For shorter outages or apartment dwellers who only need to power phones and lights, 300-1000Wh is often sufficient. The Jackery Explorer 300 and Anker SOLIX C1000 Gen 2 fit this use case without overpaying for capacity you will not use.
Match inverter output to your largest appliance
The inverter output (measured in watts) determines which appliances you can run. A 300W inverter can charge phones and laptops but cannot run a microwave. A 1500W inverter covers most kitchen appliances, power tools, and small heaters. For whole-home backup including well pumps, dryers, or central air, you need at least 3600W.
Pay attention to surge wattage as well. Some appliances like refrigerators and pumps draw 2 to 3 times their normal wattage for a fraction of a second during startup. If your inverter cannot handle the surge, the appliance will not start even if the continuous wattage is within limits.
Understand battery chemistry: LiFePO4 vs lithium-ion
Most modern solar generators use one of two battery chemistries. Lithium-ion (NMC) is lighter and cheaper, but degrades faster and has a shorter cycle life (typically 500-1000 cycles). LiFePO4 (lithium iron phosphate) is heavier and slightly more expensive, but lasts 3-10 times longer (3000-10000 cycles) and is more thermally stable.
For emergency preparedness, LiFePO4 is the clear winner. A unit you only use during outages will sit idle for months between events, and LiFePO4 holds its charge longer and degrades less during storage. Every unit on this list except the older Jackery Explorer 300 (which now ships in LiFePO4) uses LiFePO4 chemistry.
Plan for solar panel compatibility
Most solar generators accept third-party solar panels as long as the voltage and connector type match. The industry standard MC4 connector is supported by all units on this list. Pay attention to the maximum solar input wattage: the Anker SOLIX C1000 Gen 2 accepts up to 600W, the Jackery HomePower 3600 Plus accepts higher, and the smaller units accept 100-200W panels.
For fastest solar recharging, match the panel wattage to the generator’s maximum input. A 100W panel charging a 1024Wh battery takes roughly 12 hours of direct sun. A 600W panel cuts that to about 2 hours. If you live in a cloudy region, oversize your solar array by 30-50 percent to compensate.
Consider weight and portability
Solar generators range from 5 lbs (ZeroKor) to 77 lbs (Jackery HomePower 3600 Plus). If you need to evacuate with your generator, every pound matters. If your generator will live in a garage and only come out during outages, weight is less important than capacity.
The middle-ground options around 25-35 lbs (Jackery Explorer 1000 v2, Anker SOLIX S2000, Anker SOLIX C1000 Gen 2) offer the best balance of capacity and portability for most households.

The Jackery Solar Generator 1000 v2 is our top pick for most households thanks to its 1070Wh capacity, 1500W output, LiFePO4 battery, and bundled 200W solar panel. For whole-home backup, the Jackery HomePower 3600 Plus delivers 3600W output and expandable capacity up to 21kWh. Budget buyers should consider the ZeroKor 300W kit for basic phone and light charging.
How big of a solar generator do I need to power a house?
For whole-home backup including a refrigerator, lights, and communication devices, you need at least 2000Wh of battery capacity and 1500W of inverter output. For high-wattage loads like well pumps, dryers, or central air, plan for 3600W output and 3500Wh or more. The Jackery HomePower 3600 Plus (3584Wh, 3600W) and Anker SOLIX S2000 (2010Wh, 1500W) are popular choices.
How long will a 2000 watt solar generator run a refrigerator?
A typical modern refrigerator draws 100-200W while running but cycles on and off. With a 2000Wh solar generator like the Anker SOLIX S2000, you can expect 10-20 hours of runtime depending on door openings, ambient temperature, and the fridge’s age and efficiency. The S2000’s rated 35-hour fridge runtime assumes an efficient modern fridge cycling under optimal conditions.
Which is better, Jackery or EcoFlow?
Jackery and EcoFlow both make excellent solar generators, but they target slightly different buyers. Jackery units tend to be lighter, simpler, and better supported in the US market, with longer track records and larger review pools. EcoFlow units often deliver faster charging and more advanced app features. For emergency preparedness specifically, Jackery’s bundled solar panels and proven reliability give it a slight edge for most households.
Is a LiFePO4 battery better for a solar generator?
Yes. LiFePO4 batteries last 3-10 times longer than standard lithium-ion batteries (3000-10000 cycles vs 500-1000 cycles), are more thermally stable, and hold their charge longer in storage. For emergency preparedness where the generator may sit unused for months, LiFePO4 is the clear choice. Every generator on our main list except older Jackery Explorer 300 models uses LiFePO4 chemistry.
Final Verdict: Which Solar Generator Should You Buy?
After 90 days of testing eight of the top solar generators for emergencies, the Jackery Solar Generator 1000 v2 stands out as the best balance of capacity, portability, and value for most households. Its bundled 200W solar panel, LiFePO4 battery, and 1500W output cover the critical loads you need during a typical 4-to-24-hour outage without breaking the bank.
If you need whole-home backup and can handle the 77-lb weight, the Jackery HomePower 3600 Plus delivers 3600W output and expandable capacity that rivals permanent battery installations. For CPAP users and apartment dwellers, the Anker SOLIX C1000 Gen 2’s 49-minute charging and 10 ports are hard to beat. Budget shoppers should start with the ZeroKor 300W kit, but plan to upgrade if your emergency needs grow beyond phones and lights.
Whatever unit you choose, the most important step is buying it before the next outage. A solar generator sitting in your closet does you no good during a storm.
