Serious Backup Power. Wherever You Need It.
The EcoFlow DELTA Pro 3 brings high-capacity backup power to your home, RV, or off-grid setup in a flexible, expandable system. With a 4,096Wh LFP battery and 4,000W of continuous AC output, it delivers the power needed to keep essential appliances and equipment running when grid power isn't available.
With both 120V and 240V output, the DELTA Pro 3 can support demanding equipment and larger household loads. EcoFlow's X-Boost technology can accommodate compatible loads up to 6,000W, while the system provides up to 8,000W surge output for equipment with higher startup requirements.
Start with 4kWh of battery storage and expand as your energy needs grow. A single DELTA Pro 3 can reach 12kWh with two compatible extra batteries, while larger EcoFlow system configurations can scale considerably further when paired with additional DELTA Pro 3 units and compatible EcoFlow equipment.
Multiple charging options give you flexibility during extended outages and off-grid use. Recharge through AC power, solar, a vehicle, or compatible EcoFlow generator equipment, with up to 2,600W of solar input supported.
At its core is long-lasting LFP battery chemistry, rated to retain at least 80% capacity after 4,000 cycles. An IP65-rated battery, 10 ms UPS functionality, integrated wheels and an ergonomic handle round out a system designed for both dependable backup power and portability.
