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 Jackery HomePower 3000 is a powerful solar-powered generator designed mainly as a reliable home backup during outages. It offers a strong 3600W continuous power output with a 7200W surge, capable of running essential appliances like refrigerators, fans, and WiFi routers smoothly for extended periods—up to 15 hours in some cases. The large 3072Wh LiFePO4 battery is built to last, supporting about 4,000 charge cycles while maintaining good capacity, which adds impressive durability.

Charging options are flexible, including fast recharge via AC, car charger, or gas generator, and solar panel charging with the included dual 200W panels, which can bring the battery to 80% in around 9 hours under good sunlight. The unit also features a seamless UPS switch (under 20ms) to avoid power interruptions for sensitive devices like medical equipment or security cameras. Another plus is its relatively compact and lightweight design for its power class, making it easier to move and fit into homes or outdoor settings. It includes multiple outlet types (AC, USB-C, USB-A, DC, and an RV port), allowing you to plug in a variety of devices at once.

However, at nearly 60 pounds, it’s still somewhat heavy if you plan to carry it frequently over long distances. Also, while the solar panels are decent for home use, charging speed depends heavily on sunlight conditions, which may limit quick recharging during bad weather. The built-in transfer switch and ease of installation make it a good option for those wanting a ready-to-go home backup solution without complex setup. The Jackery HomePower 3000 suits users seeking a robust, durable, and versatile solar generator primarily for home emergency power, offering good portability for its size but being less suited for casual or very frequent transport.

The Jackery Solar Generator 300 is a compact and lightweight solar-powered generator ideal for outdoor activities like camping, RV trips, or emergency power backup. It features a 293Wh lithium-ion battery that delivers a steady 300W of power through two pure sine wave AC outlets, ensuring safe and stable energy for sensitive devices. Its compatibility with the 100W SolarSaga solar panel, along with an efficient MPPT controller, helps recharge the battery more quickly using solar energy, which is great for extended off-grid use.

Portability is a strong point here, as the generator weighs just over 7 pounds and has a manageable size, making it easy to carry in a backpack. Charging flexibility is impressive too—it can recharge from wall outlets, car outlets, USB-C Power Delivery ports, or solar panels. The fast recharge time of about 2 hours (using wall and USB-C ports together) is convenient for users on the go.

The unit offers multiple outlet options including two AC outlets, one 60W USB-C port, one Quick Charge 3.0 port, one USB-A port, and a DC car port, allowing you to power or charge up to six devices simultaneously like laptops, cameras, drones, and phones. This variety is handy for diverse outdoor gear. The 293Wh battery capacity is modest, making it best suited for powering smaller devices or short-term use rather than running larger appliances or extended power needs. Additionally, the solar panel is sold separately and ships separately, adding to the total cost and requiring separate setup. While the plastic build keeps weight down, it may not feel as rugged as some users expect for rough outdoor conditions. The Jackery Explorer 300 provides a reliable, portable, and user-friendly option for those needing moderate power on the go, with fast charging and good solar compatibility, making it well-suited for campers, travelers, and those preparing for occasional power outages but less ideal for heavy-duty or long-duration energy demands.
