Description
Overview
DELTA Pro Ultra is EcoFlow’s modular home battery system: an inverter on top of one or more 6kWh batteries. One inverter delivers 7.2kW at 120V and 240V, and up to three inverters reach 21.6kW with the Smart Home Panel 2. Capacity scales from 6kWh to 90kWh.
The inverter takes up to 5.6kW of solar input using its high- and low-voltage PV ports, and charges from the grid, a gas generator or an EV charging station. Its online UPS keeps power flowing with 0 ms transfer, and for loads under 2,000W it can run silently for up to 30 minutes.
Note: the inverter must be used with a DELTA Pro Ultra battery and does not include the cable for connecting a second inverter to the Smart Home Panel 2.
Who it’s for
