10 Best Solar Backup Generators 2026 in the United States

The Jackery Solar Generator 1000 v2 is a solid choice for those seeking reliable portable solar power, especially for camping, RV use, or emergency backup. Its 1070Wh LiFePO4 battery offers a long lifespan and retains most capacity even after thousands of charges, which is excellent for long-term use. Power-wise, it delivers a strong 1500W continuous output with a 3000W surge, enough to run appliances like fridges and small AC units comfortably. The two included 100W flexible solar panels are lightweight and highly efficient, making charging outdoors faster and easier. Their bendability and IP68 rating mean they can handle rough weather and fit on curved surfaces, adding versatility.

Portability is a highlight, with the whole setup being relatively light and compact for its power level, which is great if you need to move it around often. Charging options are flexible too, with a fast 1-hour emergency recharge via AC when plugged in, as well as solar charging and USB ports to power multiple devices simultaneously. The built-in smart app control adds convenience by allowing users to monitor battery status and adjust settings remotely. It is important to note that the fast charging mode requires manual activation through the app each time, which some users may find slightly inconvenient.

While the unit is rugged and offers advanced features, the price point could be less appealing to casual users who do not require extended battery life or smart controls. This generator is well-suited for those who want a dependable, efficient, and weather-resistant solar backup with strong performance and modern smart controls.

The EF ECOFLOW Solar Generator DELTA Pro features a robust 3600Wh battery capacity, making it a substantial choice for home backup, camping, RVs, and emergencies. Its power output reaches up to 3600W with the ability to boost up to 4500W, ensuring that it can handle a range of household appliances and electronic devices. The generator includes 15 versatile outlets, including 5 AC outlets and multiple USB ports, which can cater to various charging needs simultaneously.

The inclusion of a 400W portable solar panel is a significant advantage, providing efficient solar charging even under less than ideal weather conditions. The panel's 22.4% conversion rate is quite efficient in the solar panel market. With single or multiple panel setups, recharging times range from 3.5 to 11 hours depending on the configuration used, offering flexibility in charging options.

Portability is somewhat balanced, with the solar panel being foldable and easy to carry at 35.3 lbs, while the main unit weighs 99 lbs, which might be cumbersome for some users to move around frequently. The build quality is notable with an IP68 waterproof rating, ensuring durability in various environments. However, the generator and solar panel are shipped separately, which could be inconvenient if timing is critical. The smart app control feature adds modern convenience, allowing users to monitor and control the generator remotely via Wi-Fi or Bluetooth. This solar generator is an excellent choice for those needing reliable and versatile backup power, although the weight of the main unit could be a consideration for portability.

The EF ECOFLOW DELTA Pro Ultra is a powerful solar backup generator designed primarily for home use, emergency situations, and large outdoor setups like RVs or camping. Its standout feature is a large 6144Wh battery capacity, which can be expanded significantly up to 90kWh by linking multiple units—enough to keep essential home devices running for days or even weeks. With a strong 7200W continuous power output and the ability to triple that for very heavy-duty appliances, it easily supports things like central air conditioners and other large household equipment. The inverter supports both 120V and 240V, offering flexibility depending on your power needs.

Charging options are versatile and convenient: you can recharge the battery via solar panels, wall outlets, electric vehicle chargers, or even traditional generators. Notably, it charges very quickly—within 2 hours for a full charge—which is faster than many similar products. The built-in app lets you prioritize home circuits, helping to extend backup time and manage energy use smartly, which also helps reduce electricity bills when combined with solar input. The unit is designed with durability and quiet operation in mind, including a 0-ms transfer time to protect sensitive electronics during outages and a silent mode for low loads.

The product is quite heavy at nearly 183 pounds, which may limit portability despite its intended home and recreational uses. Also, it arrives in separate packages, so setup might take some time. This generator suits users looking for a robust, expandable, and smart home backup power solution who don't mind the weight and complexity involved.
