SOLAR MANAGEMENT UNIT ( SMU)

SOLAR MANAGEMENT UNIT ( SMU)

A solar management unit (SMU) is a inter connecting device with the technology to convert any inverter into a flexible solar inverter. The SMU has to be conveniently connected in between the mains power and inverter power output. Along with that, the solar panels have to be connected to the PV inputs of the SMUs and battery terminals have to be connected with the battery bank. The result is a fully featured PV solar electricity system.
