Is the inverter contactor on the AC side
The contactor on the AC side is a common contactor that must be sized in category AC-1 or AC-3 according to the national regulation of the area in which it will be installed. Power generation The generator in a power station generates 3-phase electricity. Each of these 3 phases has an alternating voltage of 230 Volt (or a different voltage. . However, the contactors in photovoltaic applications are typically installed immediately upstream and downstream of the inverter. An AC contactor is essentially a type of relay; it is electrically controlled and used to switch an electrical power circuit. When the thermostat calls for cooling, the low-voltage control circuit energizes the contactor coil, drawing contacts together and connecting the main power. .
