A solar generator is the cleanest way to back up your home: a battery power station that runs your essentials through normal outlets, paired with solar panels that recharge it from the sun. No fuel, no fumes, no noise, and unlike a gas generator it can keep going through a multi-day outage as long as there is daylight.

This guide covers the best solar generators for home backup in 2026, listing the capacity (watt-hours), continuous output (watts), and the model number for each, since people search by model and you want the exact unit.

How we picked

This is a synthesis of independent testing and reviews from CNN Underscored, OutdoorGearLab, and PowerGen Store, cross-checked against manufacturer specs. We have not bench-tested every unit. We weighted usable capacity for the price, continuous output, solar recharge speed, and how the kit fits real home-backup loads.

How the big brands differ

The 2026 market is led by four brands, and each has a lean. By the comparison testing, EcoFlow offers the fastest solar charging and the most polished app, Bluetti has among the highest capacity ceilings and strong real-world battery life, Jackery keeps things light and beginner-friendly, and Anker pushes the best specs per dollar.

What size you need

For essentials (fridge, Wi-Fi, lights, devices), a 1,000 to 2,000 Wh kit covers roughly 10 to 20 hours and refills from the sun. To run multiple large appliances or several days of backup, step up to 3,000 Wh and beyond. If you need to run 240V appliances like a well pump or dryer, look at split-phase units like the Anker SOLIX F3800. Use our sizing calculator to match a kit to your loads.

Solar generator vs a plain power station

A solar generator is just a power station bundled with panels. If you do not need solar recharge, a station alone is cheaper, see our best portable power station guide. The panels matter most when outages run long or you want true off-grid capability.

Frequently asked questions

What is a solar generator?
A solar generator is a battery power station paired with solar panels. The station stores and outputs power through normal outlets, and the panels recharge it from the sun, so unlike a gas generator it is quiet, emission-free, and can keep going through a long outage as long as there is daylight.
What size solar generator do I need for home backup?
For essentials like a fridge, Wi-Fi, and lights, a 1,000 to 2,000 Wh unit covers roughly 10 to 20 hours and refills from the sun. To run multiple large appliances or back up for days, step up to 3,000 Wh or more, and check the continuous output (watts) clears your largest appliance.
Can a solar generator power a whole house?
Large expandable systems like the EcoFlow DELTA Pro 3, or 240V units like the Anker SOLIX F3800, can run selected circuits or, with enough battery and a transfer setup, approach whole-home backup. Most solar generators are sized to cover essentials rather than the entire house at once.
How long does a solar generator last on one charge?
Divide the battery capacity by your load. A 2,000 Wh unit running a 150W fridge plus lights and Wi-Fi lasts roughly 10 to 20 hours on the battery alone, and solar recharge extends that for as long as the sun is out.
