The best solar generators in 2026, tried and tested
We tested 20 solar generators to find the most versatile devices that can provide emergency backup power and fuel off-grid activities. Three came out as the best.
20 foot containers can expand from 3,000W of solar up to 6,000W. 40 foot containers can expand from 3,000W up to 12,000W of solar in the future. We love the strategically placed solar panels on top of the container roof - we've accomplished this secure mounting with our field tested RPS Scalable Ground Mount.
Solar generators also come with USB ports for charging phones and small devices. The number of USB ports varies from two to four on smaller units and can be as high as six to eight on larger units, with a mix of USB-A 2.4-volt and 5-volt ports and USB-C with power delivery (PD) ports from 18W to 100W capacities.
RPS packages up your shipping container with all of your batteries, power components, mounting etc. safety tucked away inside the container itself. 20 foot containers can expand from 3,000W of solar up to 6,000W. 40 foot containers can expand from 3,000W up to 12,000W of solar in the future.
The Explorer 500 is one of the most popular small solar generators on the market. This 500-series power station from Jackery has been on the market since 2019, and with its friendly industrial design and bright orange-and-black utilitarian look with monochrome LCD, it has spawned many clones.
