10 Best Solar Generators 2025 in the United States

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.

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.

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.
