10 Best Solar Backup Generators 2026 in the United States

The Anker SOLIX C1000 Gen 2 is a strong choice if you want a portable solar backup generator that can handle serious power needs. Its 1,024Wh battery capacity is big enough to run multiple devices, and with 2,000W continuous output (3,000W peak), it can support things like laptops, small appliances, and even some power tools. The built-in LiFePO4 battery means it’s designed to last a long time—up to 10 years or 4,000 charge cycles with 80% capacity remaining. One standout feature is the fast charging: it can recharge fully in just 49 minutes using AC power or in about 1.8 hours with the included 200W bifacial solar panel setup, which is quite efficient for solar generators.

The device supports up to 600W of solar input, giving you good flexibility to stay off-grid. It also includes 9 power ports, making it easy to plug in multiple devices at once, and features a quick UPS switchover to keep important equipment running without interruption. Portability is decent—it’s lighter and smaller than similar models but still weighs nearly 30 pounds, so it’s portable but might not be ideal for very long hikes. The build quality feels solid with a mix of plastic and aluminum, and the Anker app adds value by letting you monitor and schedule power use to save money. If you’re camping or need reliable backup power at home, this generator fits well.

On the downside, the weight and size may be a bit bulky compared to smaller units, and while the solar panel included is efficient, you might need additional panels if you want faster or more extended solar charging. The 5-year warranty is reassuring but shorter than some competitors. To sum up, the Anker SOLIX C1000 Gen 2 delivers powerful, fast-charging, and durable solar backup power with useful smart controls, making it a solid option for campers and home users who want reliable off-grid energy without complicated setup.

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 DELTA 3 is a powerful and versatile portable solar backup generator designed for home backup, camping, and RV use. It features a substantial 1024Wh LiFePO4 battery, which is known for its long lifespan and durability—rated for about 4000 charge cycles and a 10-year daily use expectancy. This means it can last much longer than many other batteries on the market, making it a reliable long-term investment.

With an 1800W continuous power output and the ability to surge up to 2200W (3600W briefly with X-Boost), it can run up to 13 appliances at once, including high-demand devices. The inverter type is electronic, providing stable power suitable for sensitive electronics. The device supports fast charging including 500W solar input and a 1500W AC input, allowing a full charge in under an hour, which is excellent for quick turnaround during emergencies or outdoor trips.

Solar panel compatibility is good, though solar panels are sold separately. The system supports expansion up to 5kWh by adding extra batteries, giving users flexibility to increase capacity when needed. EcoFlow also emphasizes durability with an IP65 rating on the battery pack, protecting it from dust, splashes, and oil, which is beneficial for outdoor use.

Portability-wise, the unit weighs 27.5 pounds (about 12.5 kg) and has a compact design, making it manageable but not ultra-lightweight. It offers multiple charging options including AC wall, car, and solar charging, which adds to its convenience. One minor downside is that the solar panels are optional extras, so the cost can increase if you want a complete solar solution. Also, while the weight is reasonable for its capacity, it may not be the best choice if you need something very lightweight for backpacking.

The DELTA 3 is a robust, fast-charging solar generator with excellent battery life and power output suited well for home backup and outdoor activities where multiple devices need reliable power.
