Battery capacity and runtime
Battery capacity is measured in watt-hours (Wh). A higher Wh number means more stored energy, but it also increases weight and cost. For example, a 1,024Wh battery like the Anker SOLIX C1000 Gen 2 can run a 60W refrigerator for about 17 hours (1,024Wh ÷ 60W = 17 hours), while a 155Wh unit like the MARBERO 155Wh might run the same fridge for only 2.5 hours. For a three-day outage, you would need roughly 1,500–2,000Wh of capacity to keep a fridge, lights, and phone charged. The models here range from 150Wh to 1,024Wh, so choose based on how many devices you plan to power and for how long.
AC output and surge power
AC output (measured in watts) determines what appliances you can run. Continuous output is the sustained power, while surge (peak) power handles startup loads from motors or compressors. The Anker SOLIX C1000 Gen 2 delivers 2,000W continuous and 3,000W peak, enough for a refrigerator, microwave, and sump pump. Smaller units like the MARBERO 155Wh offer 100W continuous (150W peak), which is fine for laptops and CPAP machines but not for heavy appliances.
Recharge speed and methods
Fast recharging is critical during emergencies. The Anker SOLIX C1000 Gen 2 can fully recharge from a wall outlet in 49 minutes using HyperFlash technology, while the EcoFlow River 2 Max takes about 60 minutes. Solar recharge times vary: the Anker can top up in 1.8 hours with 600W of solar input, while the MARBERO 155Wh takes 6–7 hours with its included 30W panel. All models also support car charging, giving you flexibility wherever you are.
Portability and weight
Weight and size matter for camping or RV travel. The MARBERO 150Wh unit weighs just 2.8 pounds, while the EnginStar R300 is 6.5 pounds. The Anker SOLIX C1000 Gen 2 is heavier at around 30 pounds but still manageable for rolling or short carries. If you plan to move the generator frequently, a lighter model with a built-in handle or wheels is preferable.
Battery chemistry and lifespan
LiFePO4 (lithium iron phosphate) batteries are the standard for modern solar generators. They offer longer cycle life (3,000–4,000 cycles) and better thermal stability than older lithium-ion chemistries. The Anker SOLIX C1000 Gen 2 is rated for 4,000 cycles to 80% capacity, meaning it can last over a decade with daily use. The EcoFlow River 2 Max offers 3,000+ cycles, while the MARBERO and EnginStar models use LiFePO4 as well, though specific cycle ratings may vary. For occasional use, any of these will provide years of reliable service.

Frequently Asked Questions
Can a solar generator power a refrigerator?
Yes, but it depends on the generator’s capacity and the fridge’s power draw. A typical 60W refrigerator would run for about 17 hours on the Anker SOLIX C1000 Gen 2 (1,024Wh ÷ 60W). Smaller units like the MARBERO 155Wh would only run it for about 2.5 hours. Always check the fridge’s starting surge and continuous wattage before connecting.
How long does it take to recharge a solar generator?
Recharge time varies by model and method. The Anker SOLIX C1000 Gen 2 can fully recharge from a wall outlet in 49 minutes, while the EcoFlow River 2 Max takes about 60 minutes. Solar recharge times depend on panel wattage and sunlight: the MARBERO 155Wh takes 6–7 hours with its 30W panel, while the Anker can recharge in 1.8 hours with 600W of solar input.
What is the difference between a solar generator and a portable power station?
A solar generator typically includes a portable power station (battery + inverter) plus a solar panel for recharging. A portable power station is just the battery unit without a panel. In this article, all picks except the EnginStar R300 include a solar panel, making them true solar generators.
Can I use a solar generator while it is charging?
Yes, most modern solar generators support pass-through charging, meaning you can power devices while the unit recharges from solar or AC. This is useful during extended outages when you need continuous power while topping up the battery.
How do I choose the right size solar generator for my needs?
Start by listing the devices you want to power and their wattage. Add up the continuous wattage and estimate how many hours you need to run each device. Multiply wattage by hours to get watt-hours (Wh). For example, a 60W fridge for 10 hours = 600Wh. Choose a generator with at least that capacity, plus some headroom for surges. Our buying guide above has more detail. For a deeper dive, see our best expandable solar generators guide.
