10 Best Ecoflow Solar Generators 2026 in the United States

The EF ECOFLOW Solar Generator Delta 3 is a powerful and versatile solar generator suitable for home backup, camping, and RV use. It features a 1024Wh lithium iron phosphate (LFP) battery, known for its long lifespan—lasting up to 10 years with minimal capacity loss after thousands of charge cycles. The capacity can be expanded up to 5kWh by connecting additional battery packs, making it ideal for users needing more power over time.

This generator delivers 1800W continuous AC power and 100W through USB-C, allowing you to operate multiple devices or appliances simultaneously—up to 13 at once, including some power-hungry ones using its X-Boost feature. Charging is impressively fast, fully charging in under an hour via AC or solar input, with a 220W bifacial solar panel included. The bifacial panel is more efficient than typical ones, collecting energy from both sides to speed up outdoor charging.

Portability is reasonable for its category, weighing about 43 pounds, which is manageable but not ultra-light, making it best for users who can carry it short distances or transport it by vehicle. It offers various outlets, including AC and USB options, covering most device needs, and comes with multiple charging cables and a protective bag for added convenience. However, the size and weight make it less suited for backpacking or very remote treks. Additionally, since the solar panel and power station ship separately, setup may require some assembly. This model is a strong option for those seeking reliable, fast solar charging with robust power output and long battery life, ideal for emergency backup and outdoor activities where vehicle transport is possible.

The EF ECOFLOW DELTA Pro Ultra X is a powerful solar generator designed primarily for whole-home backup and extended outdoor use. With a massive battery capacity starting at 12,288Wh and expandable up to 180kWh, it can easily power essential household appliances like lights, air conditioning, and even electric vehicle chargers. Its high power output of up to 12,000 watts ensures it can handle heavy loads, making it suitable for blackout situations or off-grid living.

This generator intelligently manages energy by switching between solar, battery, and grid power automatically, which can help reduce electricity bills. It also supports adding DIY solar panels for clean, renewable charging—an important feature for users wanting to maximize solar input. The system responds instantly to power outages, keeping sensitive devices like medical equipment running without interruption.

Portability-wise, while it is not as light or compact as smaller generators, it’s still designed to be movable without professional installation. Weighing around 70 pounds and measuring roughly 27 by 19 by 9 inches, it’s manageable but not something you'd casually carry around. The unit includes multiple outlets suitable for various devices. The weight and size mean it's better suited for semi-permanent setups rather than frequent transport. Also, the inverter and extra batteries ship separately, which could add setup complexity. Its premium capabilities come with a higher price point, so it fits best for users needing serious backup power or off-grid energy solutions rather than casual camping.

The DELTA Pro Ultra X is a robust, scalable solar generator offering reliable, clean energy with smart features aimed at homeowners and outdoor power users who want flexibility and long runtime more than just simple portability.

The EcoFlow DELTA Pro 3 is a powerful and versatile solar generator designed to support a wide range of home appliances and outdoor equipment. With a large 4096Wh lithium iron phosphate (LFP) battery that can be expanded up to 48kWh, it offers substantial backup power, enough for multiple days during outages or extended camping trips. Its 4000W continuous output (6000W surge) means it can run heavy devices like air conditioners or water pumps, which many smaller generators can't handle. The unit supports 120V/240V AC outlets and includes a variety of ports for different devices, making it very flexible. It also excels in charging options, with up to 18 ways to recharge, including solar panels, wall outlets, gas generators, or EV chargers, so you have many choices depending on your situation.

Portability is decent given the weight of 115 pounds; it has a handle for easier transport but is more suited for those who don’t need to move it frequently over long distances. Its quiet operation, rated as low as 30 dB, is a big plus for indoor use or peaceful camping. The built-in app lets you monitor and control the power remotely, adding convenience. The unit’s higher price point reflects its advanced capabilities, making it a serious investment. This generator is ideal for people needing reliable, large-capacity backup power at home, RV users, or campers who want clean energy without worrying about refueling.

For those who prioritize portability or have lighter power needs, smaller, less expensive models might be better suited.
