The AC Protection box is to be used as the protection between 1 grid-connected inverter and the utility grid.
The AC Protection box is designed to protect the input to the inverter with the built in AC surge protection device and to protect the inverter from any potential cable fault that may occur between the output of the inverter and the point of common coupling with the grid.
The AC combiner board is also fitted with a power quality meter that displays information about the system such as Grid voltage, grid frequency, phase and system current (inverter output), Power factor, active and reactive power values.
