Versus the competition

All-in-one residential system 3 KW / 5 KWH / Plug & Play — residential storage

In the residential hybrid inverter segment, many market solutions require you to buy the inverter and battery separately, verify their compatibility, then make them coexist on the same wall.

One block, one reference

The EAD ESS range and the EAD-ESS-M integrate the inverter and battery in a single enclosure — less wiring, less configuration, fewer points of failure than a self-assembled architecture with separate components.

Low-frequency technology on the EAD ESS range

A design recognised for its industrial robustness and its ability to deliver 3× the nominal power at peak — a real advantage to start demanding loads (motors, pumps) without difficulty in backup mode.

IP66 on the EAD-ESS-M battery

A rarity in this price segment, allowing outdoor installation without additional protective housing.
