10 Best Solar Generators 2026 in the United States

The EF ECOFLOW Solar Generator DELTA Pro 3 is a robust and versatile solar generator designed for home use, camping, emergencies, power outages, and RVs. One of its primary strengths is its substantial 4096Wh battery capacity, which can be expanded up to 48kWh, making it capable of providing 2-4 days of backup power for an entire home. The 4000W AC output (scalable up to 12000W) ensures it can power nearly all essential appliances, including heavy-duty ones like a 3-ton central AC or a water pump. This makes it a suitable option for those needing a dependable, high-power solution during outages or off-grid scenarios.

The unit is highly flexible with multiple charging options, including solar panels, AC wall outlets, and even EV charging piles, which means users can recharge it in various situations without relying on fuel. Its portability is enhanced by a handle design, but at 115 pounds, it may not be easy to move around frequently. The generator operates quietly at 30 dB, ensuring minimal disturbance whether used indoors or outdoors. Another major advantage is its quick 10 ms switch-over capability, which ensures uninterrupted power supply to sensitive devices.

The build quality is reliable, featuring automotive-grade LFP cells and IP65-rated battery technology for an extended lifespan and durability. It also comes with a 5-year warranty, which adds peace of mind. However, potential buyers should be prepared for the bulkiness and weight, and note that the generator and solar panels are shipped separately, which may require some patience. This solar generator is ideal for someone looking for a powerful and reliable backup solution for home use or outdoor activities.

The EF ECOFLOW DELTA Pro Ultra is a powerful solar generator designed mainly for home backup and emergency use. It features a large 6144Wh battery, which can be expanded up to an impressive 90kWh by adding more batteries, making it suitable for long-term power needs. With a high 7200W output from its inverter, it can handle heavy household appliances, including large air conditioners, which is rare for portable power stations. The inverter supports both 120V and 240V, offering flexibility for different devices.

Charging options are versatile and fast—the unit can fully recharge in just 2 hours using solar panels, wall outlets, or electric vehicle chargers, which is quicker than many competitors. The EcoFlow app allows you to manage power use smartly, prioritizing essential devices and even helping reduce electricity bills by optimizing solar power usage.

This generator is quite heavy (around 183 pounds), making it less portable for casual camping or travel. It’s designed more as a stationary home backup solution than a lightweight unit you carry around. While it comes with strong durability and a 5-year warranty, it ships in multiple packages and requires some setup. Inverter features include online UPS mode with zero transfer time, protecting sensitive electronics from power interruptions. It has only three power outlets, which might require additional power strips for multiple devices. This product suits users who need a robust, expandable solar power backup for their home or RV and are willing to invest in a system that can cover extensive power needs. It is less appropriate for those seeking a lightweight, simple solar generator for occasional outdoor use.
