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 DELTA 2 solar generator is a solid choice for those seeking a clean, quiet backup power source for home, camping, or RV use. Its 1024Wh LFP (LiFePO4) battery offers a long lifespan with over 3000 charge cycles, meaning you can rely on it for years without much battery wear. The 1800W power output can handle most household appliances and tools, making it comparable to traditional gas generators but without the noise or fumes. It comes with a 160W solar panel that’s optimized to capture energy efficiently, letting you recharge faster in sunny conditions. Plus, the unit supports expanding battery capacity up to 3kWh if you need more power over time.

With 15 outlets, it offers versatile options to connect various devices at once. On the portability side, it weighs about 17.6 kilograms (nearly 39 pounds), which is reasonable but might be a bit heavy for frequent carrying over long distances. The built-in inverter and battery management system ensure stable power delivery and safety during use. Charging can be done via solar panel, AC power, or car adapter, giving flexibility based on your situation.

Though it is a bit pricey compared to smaller models, the durability, fast charging, and multiple power outputs justify the cost for users needing reliable off-grid or emergency power. This unit fits well for campers, RV owners, or homeowners wanting a green and quiet alternative to gas generators.

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.
