EG4 48V 280Ah WallMount Battery Features

On-Board LCD Touch Screen: Easy to see BMS monitoring, and selectable closed-loop communications with EG4, Schneider, Sol-Ark, Victron, Growatt, Megarevo, Luxpower, and Deye inverters.
Dual On-Board Fire Arrestors: Offer fail-safe protection against thermal runaway.
The Perfect Partner to EG4 Inverters: The optional conduit box mates up directly to the connection ports of EG4 inverters allowing a sleek and efficient installation. For other inverters or stand-alone battery installation, the conduit box plugs should be installed.
