10 Best Solar Powered Generators 2025 in the United States

The EF ECOFLOW DELTA Pro 3 solar generator is a powerful and versatile option for home backup, camping, and emergency use. Its large 4096Wh lithium iron phosphate (LFP) battery can handle heavy loads up to 4000W continuously, and even boost to 6000W or more, allowing it to power large appliances like central air conditioners and water pumps. This makes it suitable for users needing reliable energy for multiple devices or whole-home backup.

The generator supports 120V/240V output and includes 2 x 400W portable solar panels, enabling clean, renewable charging. It also offers many charging methods including wall outlets, gas generators, and EV charging stations. Portability is decent thanks to a handle design, though at 115 pounds, it requires some effort to move around. The device features multiple outlet types to connect various appliances easily, and operates very quietly at about 30 dB, suitable for indoor or outdoor use without disturbance.

Battery health is protected by automotive-grade cells and an IP65-rated battery pack, backed by a 5-year warranty. The generator and solar panels ship separately, which could be inconvenient for some users. Its size and weight might be less ideal if a truly compact or extremely portable system is desired. The DELTA Pro 3 is especially well suited for those seeking a robust, expandable solar generator capable of powering heavy-duty equipment and whole-home essentials, with an emphasis on quiet operation and battery longevity.

The EF ECOFLOW DELTA Pro solar generator is a powerful option for those needing reliable home backup or portable power for camping and emergencies. It features a large 3600Wh battery capacity and can deliver 3600W of continuous power, with a boost mode allowing up to 4500W for heavier appliances. This makes it capable of running many household devices comfortably. The generator offers 15 outlets, including 5 AC outlets and multiple USB ports, which is excellent for charging several devices at once.

Charging is flexible: it can be fully charged in under 2 hours using strong AC power and about 11 hours with a single 400W solar panel, or as fast as 3.5 hours with three panels. The included foldable 400W solar panels are lightweight (16kg each) and waterproof (IP68), which is great for portability and outdoor use in various conditions. However, the solar panels and generator come in separate packages, so setup requires some planning.

Despite its high power and versatility, the generator is quite heavy at 99 pounds, which might limit easy transport for some users. The robust build quality and smart app control add convenience, letting you monitor battery status and adjust settings remotely. This solar generator is well-suited for anyone looking for a strong, versatile backup power source, especially where solar charging is valued. Its size and weight mean it fits best in scenarios where portability is needed but not critical, such as home backup and RV trips rather than frequent long-distance carrying.

The Jackery Solar Generator 1000 v2 is a robust and versatile solar-powered generator, boasting a 1,070Wh battery capacity and a 1,500W AC output, which can handle multiple appliances, including power-hungry devices like AC units and fridges. It has an impressive 3,000W surge peak, making it suitable for various power needs during outdoor activities, off-grid living, and emergencies. The generator's relatively lightweight build at 23.8 pounds and foldable handle enhance its portability, making it easy to transport and set up in different locations.

The 200W solar panel included ensures compatibility with clean energy sources, though it is shipped separately from the generator itself. A standout feature is its fast charging capability, allowing the power station to charge from 0% to 100% in just one hour when using the emergency charging mode via the Jackery App. However, to optimize battery health, the default charging time is 1.7 hours. The generator includes multiple outlets: two USB-C, one USB-A, one DC car port, and three AC ports, along with LED lights, providing flexibility for different devices. The durable LiFePO4 battery promises a lifespan of over 4,000 charge cycles, maintaining 70% capacity, translating to more than 10 years of reliable use.

One potential drawback is that the emergency charging mode needs to be enabled manually through the app each time, which may be inconvenient for some users. Additionally, it is important to provide an actual address for delivery, as the product cannot be shipped to a PO Box. With excellent customer reviews and a solid 4.6 out of 5-star rating, the Jackery Solar Generator 1000 v2 is highly regarded for its performance, making it a great choice for those needing a reliable and powerful portable energy solution.
