Best Home Backup Solar Generators: How the Top Picks Compare
Which model has the most power output?
The clear winner here is the EF ECOFLOW DELTA 2 Max with a massive 2400W continuous output, enough to run most household appliances simultaneously. The Jackery Explorer 1000 v2 offers 1500W, which covers essentials like a fridge and lights, while the EF ECOFLOW Delta 2 sits in the middle at 1800W. For heavy-duty needs, the DELTA 2 Max is unmatched among this group.
How long can they run a fridge?
A typical mini-fridge uses about 100W per hour. The EF ECOFLOW Delta 2 (1024Wh) could theoretically run it for about 10 hours, while the Jackery Explorer 1000 v2 (1070Wh) would stretch to nearly 11 hours. The EF ECOFLOW DELTA 2 Max (2048Wh) doubles that to over 20 hours. The EcoFlow River 2 Max 500 (499Wh) would provide around 5 hours, and the Apowking (146Wh) is best for short-term phone/laptop charging, not extended fridge use.
Which is the most portable for home use?
For home backup, you might not move it often, but portability still matters. The EcoFlow River 2 Max 500 weighs just 13.3 lbs, making it easy to carry from room to room. The Apowking is even lighter at around 3-4 lbs, but its capacity is limited. The EF ECOFLOW Delta 2 is heavier but still manageable, while the DELTA 2 Max is a larger unit best left in one place. For a lighter option that still offers decent power, see our best portable electric generators for camping.
Which charges fastest from solar?
The EF ECOFLOW Delta 2 accepts up to 500W of solar input, recharging its 1024Wh battery in a few hours of good sun. The EF ECOFLOW DELTA 2 Max can take up to 1000W solar input, refilling its 2048Wh pack in roughly 2-3 hours. The Jackery Explorer 1000 v2 supports up to 200W solar input, taking about 5-6 hours for a full charge. The EcoFlow River 2 Max 500 charges in as fast as 2.3 hours with 220W solar. The Apowking includes a 40W panel, ideal for trickle charging over a day.

Frequently Asked Questions
Can I run my whole house on a solar generator?
For essential circuits (fridge, lights, modem, sump pump), a model like the EF ECOFLOW DELTA 2 Max with 2400W output and 2kWh+ capacity can handle it. For larger appliances like central AC or electric oven, you’d need a much larger system or a gas generator. See our whole home backup guide for more.
How long does it take to charge a solar generator from the sun?
It depends on solar panel wattage and sun conditions. For example, the EF ECOFLOW Delta 2 with its included 220W panel can fully charge in about 4-6 hours of peak sun. The Jackery Explorer 1000 v2 with a 200W panel takes roughly 5-6 hours. Cloudy days will extend charging time.
Are solar generators safe to use indoors?
Yes, they produce no fumes or carbon monoxide, making them safe for indoor use. However, ensure proper ventilation for the battery’s cooling vents. Never use a gas generator indoors.
What is the difference between watts and watt-hours?
Watts (W) measure the power output at any moment (like how much a device draws). Watt-hours (Wh) measure the total energy storage capacity. A 1000Wh battery can run a 100W device for 10 hours, or a 500W device for 2 hours.
