EcoFlow DELTA Pro 3 Portable 4096Wh Power Station

EcoFlow DELTA Pro 3 Portable Power Station 4000W 4096Wh LiFePO4

The EcoFlow DELTA Pro 3 Portable Power Station is a high-capacity portable energy system designed for home backup, off-grid power, motorhomes, workshops and demanding electrical equipment. Combining a substantial 4096Wh battery capacity with 4000W continuous AC output, it provides enough power for everything from everyday electronics to high-demand household appliances and power tools.

At its core is a long-lasting LiFePO4 battery rated for approximately 4000 cycles before reaching 80% of its original capacity. The built-in inverter delivers up to 4000W continuous AC power with an 8000W surge capability, while EcoFlow X-Boost technology supports compatible appliances with power requirements of up to 6000W.

The DELTA Pro 3 is also designed to grow with your energy requirements. Its standard 4096Wh capacity can be expanded using up to two compatible EcoFlow Smart Extra Batteries, creating a system with approximately 12kWh of total storage.

For off-grid installations, the DELTA Pro 3 supports up to 2600W of solar input across two separate PV inputs. The high-voltage input supports up to 1600W while the low-voltage input supports up to 1000W, allowing substantial solar arrays to recharge the battery without relying entirely on mains electricity.

Fast mains charging provides up to 2900W AC input, while vehicle charging is also supported. Integrated Wi-Fi and Bluetooth connectivity provide monitoring and control through the EcoFlow app, while its wheels and integrated handle help make the substantial 51.5kg unit easier to reposition.
