10 Best Solar Generators 2025 in the United States

The Jackery HomePower 3000 is a powerful solar generator designed to provide reliable backup power for your home and outdoor activities. It features a large 3,072Wh lithium iron phosphate (LiFePO4) battery, known for long life and safety, which can handle up to 3,600 watts of continuous power and surges up to 7,200 watts. This means it can keep essential appliances like refrigerators, fans, and lights running smoothly during power outages for hours or even days. The built-in UPS switches power within 20 milliseconds, ensuring important devices like security systems or medical equipment don't lose power unexpectedly.

The generator supports charging through various methods including AC outlets, car chargers, gas generators, and solar panels (two included 200W panels), providing flexibility whether you're at home or traveling. It can recharge quickly—fully in about 1.7 hours with hybrid AC/DC charging, or up to 80% in 9 hours with solar panels. While it is the lightest and smallest in its class, weighing about 60 pounds, it’s still somewhat bulky for casual carrying but manageable for those prioritizing home backup or RV use. Jackery’s AI-driven ChargeShield 2.0 technology helps speed up charging and extends battery life, promising around 4,000 cycles. The device's build quality is solid with a honeycomb bottom shell for added strength.

Despite its portability improvements, it remains heavier than smaller power stations, and the solar charging time may be longer than some users want for emergency use. Also, the initial cost might be higher than simpler models, but the tax credit could help offset this. This solar generator is well-suited for homeowners looking for dependable, high-capacity backup power and RV users needing versatile, clean energy on the go.

The EF ECOFLOW Solar Generator DELTA2 is a robust solution for those seeking clean and portable power, perfect for camping, RVs, or as a backup at home. One of its standout features is the impressive 1800W output, which allows it to power most household appliances without any emissions or noise, making it a great alternative to traditional generators. Its LFP battery offers a significant lifespan of over 3000 charge cycles, which means this unit will last for years with proper care. The ability to expand its capacity from 1kWh to 3kWh by adding extra batteries is a great plus for users with greater power needs.

Portability is another strong point, as the DELTA2 and its 220W bifacial solar panel are designed to be mobile, making them suitable for outdoor activities. The solar panel's ability to capture up to 25% more energy thanks to its bifacial design enhances its efficiency significantly.

The EF ECOFLOW Solar Generator DELTA2 is an excellent choice for individuals or families who need reliable, eco-friendly power for outdoor adventures or backup during outages.

The EF ECOFLOW Portable Power Station 3600Wh DELTA Pro is a robust and versatile solar generator. It shines with its large 3600Wh battery capacity, making it suitable for home use, power outages, camping, RV trips, and emergencies. The power output is impressive, offering 3600W with the potential to expand up to 4500W using X-Boost technology, and even up to 7200W with double units, which allows it to handle heavy-duty devices effortlessly.

The device supports up to 15 different output methods, providing maximum flexibility to power multiple devices simultaneously. It is compatible with solar panels and features fast charging capabilities, notably recharging fully in as little as 2.7 hours with wall outlets or 2.8 hours with solar panels, thanks to its X-Stream charging technology. Moreover, it offers five different ways to charge, including via solar, wall outlets, EV stations, car outlets, and a smart outdoor generator, ensuring you are covered in various scenarios.

However, its weight of 99 pounds could be a drawback for portability, making it less convenient to move around frequently. The app control feature is a modern touch, allowing users to monitor and control the power station remotely via Wi-Fi or Bluetooth. Durability is ensured with Lifepo4 battery technology, which is known for its longevity and safety. While the product's price point may be on the higher side, the value provided in terms of capacity and versatility makes it a strong contender for those in need of a reliable power source.
