A removable LCD control module makes field servicing more straightforward, and the unit supports dual output for separating critical and non-critical loads.

PV input voltage range is a wide 90–450VDC through a built-in 120A MPPT solar charge controller, and “friendly & flexible” generator support allows diesel generator access with full power discharge and automatic battery charge/discharge management. Built-in WiFi (requiring the companion app) handles mobile monitoring, and an OTG USB function adds local data transfer capability. BMS integration runs over RS485, CAN-BUS and RS232.
