10 Best Off Grid Solar Generators 2025 in the United States

The EF ECOFLOW DELTA Pro 3 is a robust contender in the off-grid solar generator category, designed to cater to a range of power needs from home use to camping and emergencies. Its impressive 4096Wh battery capacity is a standout feature, with the ability to expand up to 48kWh if necessary, which makes it a reliable choice for extended power outages or off-grid living. The 4000W AC output, capable of scaling up to 12000W, means it can power almost any household appliance, including heavy-duty ones like central AC units or water pumps. This power station is versatile in its charging options, supporting solar, gas, and EV charging among others, effectively removing the hassle of frequent refueling.

Despite its significant power capacity, the DELTA Pro 3 is quite user-friendly with a plug-and-play setup that even a child could manage. Its portability is somewhat hampered by its weight of 150 pounds, but the inclusion of a handle design enhances ease of movement. The use of automotive-grade LFP cells and IP65-rated technology protects the battery, promising durability and a long lifespan, further backed by a 5-year warranty.

It's an ideal choice for residential use, RVs, or as a backup in power outages, appealing to those who prioritize a durable, powerful, and multi-functional energy solution. However, potential buyers should be prepared for its size and weight when contemplating mobility needs. The noise level is kept to a minimum thanks to X-Quiet technology, making it suitable for indoor use without disturbance.

The Jackery Solar Generator 1000 v2 is a solid choice if you need a reliable and portable power source for outdoor activities, emergency use, or off-grid living. It has a good battery size of 1,070 watt-hours, which means it can power essential devices like mini fridges, AC units, and small appliances for several hours. Its 1,500W continuous power output and 3,000W surge capacity allow it to handle devices with higher startup power needs. The built-in LiFePO4 battery type is a strong point because it lasts a long time—over 10 years with many recharge cycles—so you won’t need to replace it often. The 200W solar panel adds clean energy capability, although solar input is not very large, so it may take some time to recharge in the sun alone unless you add more panels.

One standout feature is the option for very fast charging—getting fully charged in about an hour with the app's emergency mode, which is handy if you have limited charging time. The device is quite portable at 23.8 pounds and has a foldable handle, making it easier to carry than some heavier generators. It also has a pure sine wave inverter for safe, stable power suitable for delicate electronics. The multiple output ports, including USB-C with fast charging, AC outlets, and car port, make it versatile for charging different gadgets simultaneously.

It is worth noting that the solar panel and generator ship separately, which could be inconvenient for some users. Also, while the battery is expandable in theory, this model does not have easy options to add more battery capacity, limiting longer-term scalability. If you’re looking for a user-friendly, durable, and reasonably powerful solar generator mainly for camping, RV use, or emergency backup, the Jackery 1000 v2 fits well. For those needing very high solar input or expandable capacity for extended off-grid living, other models might be more suitable.

The Jackery Solar Generator 300 is a compact and lightweight option for portable power off-grid. With a 293Wh lithium battery and a 300W pure sine wave inverter, it provides clean and stable electricity that's safe for sensitive devices like laptops and cameras. Its two AC outlets and multiple USB ports allow charging of up to six devices simultaneously, which is convenient for camping or travel. The included 100W SolarSaga solar panel efficiently recharges the battery through an MPPT controller, making solar power a practical option, with recharge times depending on sunlight availability.

One notable feature is its rapid recharge capability—approximately 80% in 2 hours when using wall and USB-C PD ports together. Weighing only 7.1 pounds, it is easy to carry and fits well into backpacks for outdoor activities. However, the battery capacity and 300W power limit mean it is not suitable for high-power appliances or long-term off-grid living; it is ideal for charging small electronics and running low-power devices during short trips or emergencies.

Although it lacks built-in expandability for extra batteries, its solar compatibility and multiple charging options provide flexibility. This generator is well suited for campers, RV users, and anyone needing reliable backup power in a lightweight, portable package.
