Product Overview
The rack-mounted format fits standard 19-inch server and battery cabinets, which keeps installations clean and organised. The front LCD gives a quick status read without needing to open the inverter app or monitoring software, which is useful during commissioning and service visits.
The built-in BMS handles overvoltage, undervoltage, overcurrent, short circuit and temperature protection. Communication with the inverter is via RS485, RS232 or CAN depending on the inverter make and model. The correct protocol and cable must be selected during installation.
Leoch lists compatibility with a wide range of inverter brands including Growatt, Sofar, GoodWe, Solis, Victron, Voltronic and others. This list is guidance only and does not constitute official approval from every manufacturer. Compatibility, firmware version and BMS protocol must be confirmed before installation.
