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 Jackery Solar Generator 300 is a compact and lightweight portable power station with a 293Wh lithium-ion battery and a 300W pure sine wave inverter, making it a solid choice for outdoor activities like camping, road trips, or emergency backup. Its battery capacity is suitable for charging smaller devices such as phones, laptops, drones, and cameras simultaneously, thanks to multiple output ports including two AC outlets, USB-C PD, USB-A fast charge, and a car port. This versatility makes it easy to power several gadgets at once.

Charging is quite flexible and efficient; you can recharge up to 80% in about 2 hours using a wall outlet and USB-C PD port together. Besides AC power, it supports solar charging with the Jackery SolarSaga 100W panel, which includes an MPPT controller for faster and more efficient solar recharge. The solar panel is sold separately, so keep that in mind if you want a full solar charging setup. At just over 7 pounds, the unit is highly portable and easy to carry in a backpack, which is great for users who prioritize mobility. The build quality is decent with a sturdy plastic shell, but it’s not designed for heavy rough use or extremely harsh environments. The pure sine wave inverter ensures stable and safe power output, which is important for sensitive electronics.

The 293Wh capacity and 300W power limit mean it won’t run high-power appliances or provide extended backup for larger devices. Also, the solar panel requires separate purchase, adding to the overall cost if you want the complete solar generator experience. The device is best suited for light to medium power needs rather than heavy-duty use. The Jackery Solar Generator 300 provides a good blend of portability, convenient charging options, and clean power delivery, making it ideal for camping enthusiasts, light emergency backup, and those who need reliable off-grid power for small electronics. If longer runtimes or higher wattage output are required, larger models might be more appropriate.

The EcoFlow DELTA Pro 3 is a powerful and flexible solar backup generator designed for home use, camping, and emergencies. It offers a large 4096Wh lithium iron phosphate (LFP) battery, which can be expanded up to 48kWh, making it suitable for powering many household appliances, including heavy-duty devices like central air conditioners or water pumps. Its 4000W output (6000W starting, up to 12000W with expansion) means it can handle a wide range of power needs without struggling. The unit supports multiple charging methods—solar panels, wall outlets, gas generators, and even EV charging stations—giving you great flexibility in keeping it charged. It also features a high-quality inverter that delivers clean, reliable AC power and switches to backup mode in just 10 milliseconds, ensuring your devices stay running smoothly during outages.

On the portability side, while the DELTA Pro 3 has a handle for easier transportation, it weighs 115 pounds, which means it's not something you'd carry around casually but still manageable for moving between home, RV, or campsite. The build quality is excellent, with automotive-grade battery cells and IP65-rated battery protection, so it’s durable and weather-resistant. The unit runs very quietly, making it ideal for indoor or outdoor use without noise disturbance.

If you want a dependable, high-capacity solar backup generator with lots of charging options and smart app control, this is a solid choice. Its relatively heavy weight and likely higher price point might not suit users needing something lightweight or more budget-friendly. This product is well suited for those who want serious power backup at home or in an RV and are ready to invest in premium features and expandability.
