10 Best Solar Generators 2025 in the United States

The EF ECOFLOW Solar Generator 120V/3.6KWh DELTA Pro with 400W Portable Solar Panel is a robust solution for home backup and outdoor activities like camping and RV use. It boasts an impressive battery capacity of 3600Wh and can deliver up to 3600W of power output, making it suitable for powering various household appliances and devices. Through its x-boost technology, it can handle surges up to 4500W, offering emergency power when needed. This generator can be recharged quickly, achieving full charge in 1.8 hours with a 240V outlet, or 2.7 hours with a 1800W wall outlet.

The solar panel itself, with a high efficiency rate of 22.4%, can recharge the power station in 11 hours using a single panel or 3.5 hours with three panels, ensuring reliable energy even in variable weather conditions. Portability is emphasized with the foldable design of the 16kg solar panel, which has an IP68 waterproof rating for durability. The generator provides versatility with 15 different output ports, including AC, USB-A, USB-C, DC, and Anderson ports, accommodating a wide range of devices.

The EcoFlow app enhances user control through smart monitoring and customization of settings remotely via Wi-Fi or Bluetooth. However, the generator is quite heavy at 99 pounds, which might limit ease of transport. Additionally, the high efficiency comes at a premium cost, and the separate shipping of the generator and solar panel might be inconvenient for some users. Despite these drawbacks, this solar generator offers powerful and efficient performance for residential and outdoor use.

The EF ECOFLOW DELTA 2 solar generator is a solid choice for those needing a reliable and portable power solution for camping, RV trips, or home backup. Its 1024Wh lithium iron phosphate (LFP) battery means it can store a substantial amount of energy, and with a high cycle life of over 3000 cycles, it promises many years of use. You can power up to 15 devices simultaneously with a strong 1800W continuous output and 2700W surge, enough for most small home appliances or outdoor gear.

It comes with two 100W solar panels, allowing for solar recharging in about 5 hours; adding a third panel can speed this up to around 2.6 hours, which is quite fast compared to many competitors. The system is also expandable to 3kWh by adding extra batteries if you need more capacity. At 27 pounds and compact size, it’s fairly portable but might be a bit heavy for some to carry easily over long distances. Safety is well-covered with an advanced battery management system that prevents overcharging and overheating.

One downside is that the solar panels and the generator arrive separately, which might be slightly inconvenient. Also, while it handles a wide range of devices, it may not be suited for very high-power equipment. This solar generator balances power, speed, and durability well, making it a good fit for outdoor enthusiasts and anyone wanting an eco-friendly backup power source.

The Jackery HomePower 3000 is a powerful and compact solar generator designed primarily for home backup and emergency use. With a large 3072Wh Lithium Iron Phosphate (LiFePO4) battery, it can power essential household appliances like refrigerators, fans, and lights for many hours during an outage. Its 3600W continuous output and 7200W surge capacity mean it can handle several devices at once, including sensitive equipment like medical refrigerators or security cameras, thanks to its fast and smooth UPS switching.

The generator offers versatile output options including multiple AC outlets, USB-C, USB-A, and even an RV-specific port, which makes it useful for both home and outdoor activities. Charging is flexible and relatively quick: it can recharge fully in under two hours using AC power or about 9 hours with solar panels (sold separately), supporting efficient off-grid use. Despite its strong battery and output, it remains lighter and smaller than many competitors, weighing just under 60 pounds and featuring a sturdy, space-saving design.

Its battery technology promises a long lifespan with thousands of charge cycles, enhancing reliability over time. While portable relative to its capacity, its weight and size might still be challenging for frequent transport by one person, especially compared to smaller models. Since solar panels are optional, additional investment is needed to fully utilize solar charging. For anyone needing a robust, reliable power source for home emergencies or RV trips, the HomePower 3000 delivers impressive performance and durability, though it requires some planning around its portability and solar panel purchase.
