10 Best Ecoflow Solar Generators 2026 in the United States

The EF ECOFLOW Solar Generator 3.6KWh DELTA Pro is designed to be a robust home backup solution and an outdoor power source for camping or RV needs. One of its main strengths is the large 3600Wh battery capacity, which can handle high power outputs up to 4500W with the X-Boost technology. This makes it capable of powering most household appliances in an emergency. It also features five AC outlets and a total of 15 various ports, making it versatile for charging multiple devices simultaneously. The generator's smart app control adds convenience, allowing you to monitor and manage charging status and settings remotely via Wi-Fi or Bluetooth.

The included 400W solar panels are highly efficient with a 22.4% conversion rate and are both portable and durable, with an IP68 waterproof rating. However, the generator itself is quite heavy at 99 pounds, which may limit its portability for some users. Another potential drawback is the relatively long recharge time with a single solar panel, which is around 11 hours. For quicker charging, multiple panels are needed, which could be an added expense. Additionally, the generator and solar panels are shipped separately, which might require some coordination for setup.

The DELTA Pro is suited for those needing a powerful and versatile power source with good efficiency and multiple charging options, despite its weight and potential additional costs for faster solar charging.

The EF ECOFLOW DELTA Pro Ultra with Smart Home Panel 2 is a robust solar generator suitable for significant power needs in homes or recreational vehicles. With an impressive battery capacity of 6144Wh, it can provide prolonged power backup. Its high-power output of 7200W, supporting both 120V and 240V, makes it capable of running heavy household appliances, including a 3-ton central air conditioner. This feature is particularly beneficial during power outages, as it can handle substantial electrical loads.

A standout attribute is its multiple charging options, offering flexibility in how the unit is recharged. Whether using solar, electric vehicle piles, wall outlets, or outdoor generators, this unit ensures quick and efficient recharging, claiming a full charge in just two hours. Portability may not be its strongest aspect, as the unit is relatively heavy at 234 pounds, making it more of a stationary solution rather than a portable one.

The included Smart Home Panel 2 offers intelligent energy management, allowing users to customize their home power usage and prioritize certain circuits to extend backup time. An automatic 20-ms switchover feature ensures seamless transitions during outages, preventing disruptions to home life. It supports further expansion to 90kWh, which is advantageous for those seeking scalable power solutions. While the product offers an excellent energy management system and high output, its weight and size might be limiting factors for those needing mobility. With a favorable customer rating of 4.2 stars, it is appreciated for its reliability and performance, especially in residential settings. However, potential buyers should consider their specific needs, particularly regarding mobility and installation space, given its substantial dimensions.

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.
