10 Best Solar Generators 2025 in the United States

The Jackery HomePower 3600 Plus is a powerful solar generator designed primarily as an essential home backup, especially useful during emergencies or for RV use. It offers a substantial battery capacity of 3584Wh, which can be expanded up to 43kWh by connecting multiple units, making it capable of powering a small household for over two weeks. With a strong 3600W AC output (and up to 7200W in parallel mode), it can handle heavy appliances like pumps, heaters, and dryers, which is not common in many portable generators.

In terms of safety and durability, this model stands out with lithium iron phosphate (LFP) battery cells that resist high temperatures (tested up to 302 °F) and promise up to 6,000 charge cycles with a lifespan of about 10 years. This makes it reliable even in extreme weather conditions, including freezing temperatures. The generator can be charged in multiple ways—via AC power, solar panels, or a gas generator—with hybrid charging allowing a full recharge in just 2 hours, which is quite fast for a battery this size.

Portability is handled surprisingly well given its capacity; although it weighs 77.2 pounds, it features a compact design with wheels and a telescoping handle, making it easier to move around than many similarly sized units. It has a plug-and-play setup, so no complicated installation is needed, making it user-friendly for those without technical experience. Due to its size and weight, it is less suitable for frequent travel or backcountry use where extreme portability is crucial. This solar generator is ideal for homeowners seeking a reliable backup power source or RV owners needing extended power capacity, excelling in providing clean, quiet, and steady power for significant household demands.

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 Anker SOLIX C1000 Gen 2 is a powerful and reliable solar generator that offers a solid 1,024Wh battery capacity, allowing it to power multiple devices for extended periods. Its 2,000W continuous output (with 3,000W peak) through 9 different ports lets you run everything from small appliances to essential electronics like laptops and CPAP machines with ease.

A standout feature is its ultra-fast recharge capability—using HyperFlash technology, it can fully recharge from an AC source in just 49 minutes or from solar panels in about 1.8 hours when using up to 600W of solar input, making it especially handy for camping or emergency backup when quick power is needed. The included 200W bifacial solar panel is efficient and supports sustainable off-grid recharging.

In terms of portability, the unit is fairly compact and 11% lighter than similar products, though at around 29.5 pounds, it remains somewhat heavy for carrying over long distances. The LiFePO4 battery is built for longevity, promising at least 80% capacity after 4,000 charging cycles, which benefits frequent users over many years. Safety features like a 10 ms UPS backup ensure critical devices stay powered without interruption, while the accompanying app offers smart control for scheduling power use and avoiding high electricity costs. The fast charging, durable battery, and solid power output make this generator well-suited for campers, outdoor enthusiasts, and anyone needing dependable portable solar power.
