10 Best Solar Generators 2025 in the United States

The Jackery Solar Generator 1000 V2 is a robust and versatile power solution for those who need reliable electricity in outdoor settings, off-grid living, or during emergencies. With a battery capacity of 1,070Wh and a powerful 1,500W AC output, this generator can handle multiple devices, from small appliances to larger items like refrigerators and AC units. Its lightweight design (23.8 lbs) and foldable handle make it easy to carry around, enhancing its portability.

Additionally, the inclusion of a 200W solar panel ensures you can recharge the generator using renewable energy sources, although the solar panel is shipped separately. A standout feature is its fast charging capability, allowing you to charge from 0% to 100% in just one hour with the emergency charging mode, although this needs to be activated via the Jackery App. The generator also comes with various ports (USB-C, USB-A, DC car port, and AC ports) to charge multiple devices simultaneously, and it includes built-in LED lights for convenience.

Durability is well-covered, with the LiFePO4 (LFP) battery offering a long lifespan of over 10 years and retaining 70% capacity after 4,000 charge cycles. However, potential buyers should note the need to provide a physical address for shipment, as PO Box addresses are not accepted. Users also need to activate the emergency charging function each time via the app to benefit from the one-hour fast charging. Despite these minor inconveniences, the Jackery Solar Generator 1000 V2 is a reliable and customer-approved choice for portable power needs.

The EF ECOFLOW Solar Generator DELTA2 is a robust solution for those seeking clean and portable power, perfect for camping, RVs, or as a backup at home. One of its standout features is the impressive 1800W output, which allows it to power most household appliances without any emissions or noise, making it a great alternative to traditional generators. Its LFP battery offers a significant lifespan of over 3000 charge cycles, which means this unit will last for years with proper care. The ability to expand its capacity from 1kWh to 3kWh by adding extra batteries is a great plus for users with greater power needs.

Portability is another strong point, as the DELTA2 and its 220W bifacial solar panel are designed to be mobile, making them suitable for outdoor activities. The solar panel's ability to capture up to 25% more energy thanks to its bifacial design enhances its efficiency significantly.

The EF ECOFLOW Solar Generator DELTA2 is an excellent choice for individuals or families who need reliable, eco-friendly power for outdoor adventures or backup during outages.

The EF ECOFLOW DELTA 2 Max stands out with its large 2048Wh LiFePO4 battery, which is known for a long lifespan—about 3000 full charge cycles—meaning you can expect many years of reliable use. It offers a strong 2400W continuous power output and can handle short bursts up to 3400W, thanks to its X-Boost mode, so it can power nearly all household devices and many high-wattage appliances. This makes it suitable for camping, RV trips, or emergency home backup. The included 220W bifacial solar panel is designed to capture more sunlight by using both sides, improving charging speed and efficiency. It’s also lightweight and foldable, improving portability for outdoor use.

You can charge the generator quickly using AC power or solar panels, reaching 80% charge in just 43 minutes with combined inputs, which is impressive for a solar generator of this size. The unit has 15 outlets, providing plenty of options to plug in different devices simultaneously. It’s built with durable ABS material, and the solar panel has a tough tempered glass surface with IP68 waterproof and dustproof ratings, making the setup robust enough for outdoor conditions.

One downside is the weight—at 71 pounds, it’s not the easiest to carry for long distances, so it’s better suited for car camping or stationary use. Also, the main unit and solar panel ship separately, which may require some patience during delivery. The DELTA 2 Max combines high power, fast charging, and durability, making it a strong choice for those needing dependable portable solar power, though its weight and separate shipping might be minor inconveniences.
