Battery Capacity: How Much Wh Do You Need?
Battery capacity is measured in watt-hours (Wh) and determines how long your devices will run. A 1024Wh unit like the EF ECOFLOW Delta 2 or OUPES Mega 1 can power a 60W CPAP machine for about 17 hours, or a 150W refrigerator for nearly 7 hours. The 2048Wh DELTA 2 Max doubles that runtime, making it suitable for overnight home backup. For reference, the Apowking 146Wh unit can charge a smartphone about 10 times or run a 10W LED light for 14 hours. To estimate your needs, add up the wattage of the devices you plan to run and multiply by the hours you need them, for example, a 3-day outage requiring 300W of continuous load would need roughly 300W x 72h = 21,600Wh, which is beyond portable solar generators, so focus on essentials only.
Inverter Output: What Can You Power at Once?
The inverter’s continuous wattage rating tells you the maximum load you can run simultaneously. A 1800W inverter (like the Delta 2 and DELTA 3) can handle a microwave (1000W) plus a TV (100W) and lights (50W) at the same time. The 2400W DELTA 2 Max adds headroom for a small air conditioner or a refrigerator plus a freezer. The OUPES Mega 1 offers 2000W continuous with a 4500W surge to start motors. The Apowking’s 100W rated output limits it to small electronics only. Always check the starting surge of appliances like refrigerators or pumps, which can be 2-3 times their running wattage.
Solar Input: How Fast Can It Recharge?
Solar input wattage determines how quickly the generator can recharge from solar panels. The DELTA 2 Max accepts up to 1000W of solar input, allowing it to reach 80% charge in 43 minutes with combined AC and solar. The DELTA 3 takes 500W solar input, and the OUPES Mega 1 supports up to 800W. The EF ECOFLOW Delta 2 with 220W panel can take up to 500W, while the Apowking’s 40W panel is best for trickle charging over several hours. If you plan to rely heavily on solar, a higher input rating means faster recharging during sunny hours.
Battery Chemistry and Lifespan
All five picks use LiFePO4 (LFP) batteries, which are known for safety and long cycle life. The EF ECOFLOW Delta 2 and DELTA 2 Max offer 3000 cycles to 80% capacity, while the DELTA 3 boasts 4000 cycles, translating to about 10 years of daily use. The OUPES Mega 1 also uses LFP with 3500+ cycles. The Apowking uses LFP as well, though its smaller capacity means you’ll likely replace it sooner if used daily. LFP batteries are heavier than older lithium-ion but last significantly longer, making them a better investment for frequent use.
Portability and Included Accessories
If you need to carry the generator frequently, weight and included panels matter. The EF ECOFLOW Delta 2 with 220W panel is a complete kit with a carry case, while the DELTA 3 and OUPES Mega 1 are sold without panels, so you’ll need to buy them separately. The Apowking is the lightest at under 5 lbs, perfect for day hikes. The DELTA 2 Max is the heaviest at over 50 lbs, best for stationary use. Check whether the unit includes a solar charging cable, AC adapter, and any carrying case to avoid extra costs.

Frequently Asked Questions
Can a 1000W solar generator run a refrigerator?
Yes, most 1000W-rated solar generators can run a standard refrigerator (typically 150-300W running) for several hours. For example, the EF ECOFLOW Delta 2 with 1024Wh capacity can power a 150W fridge for about 6-7 hours. However, always check the refrigerator’s starting surge, which can be 2-3 times its running wattage.
How long does it take to charge a 1000W solar generator with solar panels?
Charging time depends on the solar input wattage. With a 220W panel, a 1024Wh generator like the EF ECOFLOW Delta 2 takes about 4-5 hours in full sun. With a 500W solar array, the same generator can charge in under 2 hours. The DELTA 3 can achieve 80% charge in 30 minutes when using both AC and 500W solar simultaneously.
Are solar generators safe to use indoors?
Yes, solar generators produce no fumes or carbon monoxide, making them safe for indoor use during power outages. Unlike gas generators, they can be used in a bedroom, living room, or office without ventilation concerns. Always keep them away from water and follow the manufacturer’s safety guidelines.
What is the difference between a solar generator and a portable power station?
The terms are often used interchangeably, but a solar generator typically includes a solar panel, while a portable power station is the battery unit alone. For example, the EF ECOFLOW Delta 2 with 220W panel is a solar generator, while the OUPES Mega 1 is a power station that requires separate panels. Both store energy for later use.
Can I expand the capacity of these solar generators?
Several models offer expansion options. The EF ECOFLOW Delta 2 can be expanded from 1kWh to 3kWh with extra batteries, the DELTA 3 expands to 5kWh, and the DELTA 2 Max expands to 6kWh. The OUPES Mega 1 also expands to 5kWh. The Apowking 146Wh unit is not expandable. For more on expandable systems, see our best LiFePO4 portable power stations guide.
