PV AC combiner box refers to a box that combines the output currents of multiple PV inverters into a combiner box, which is then connected to a circuit of an integrated switch cabinet in the on-site power distribution system to realize the combining and AC conversion functions of multiple PV inverters. It is an important part of the PV power station.
Combining function: The internal components of the combiner box are combined to effectively combine the output currents of multiple PV inverters and connect them to a circuit of the integrated switch cabinet to realize the AC conversion function of multiple PV inverters.
2. Current protection function: The PV AC combiner box has a built-in current protection device, which can constrain the output current of the combiner box in real time when the system fails or the PV inverter is short-circuited, ensuring the safe operation of the combiner box.
3. Lightning protection function: The PV AC combiner box is equipped with a lightning protection device, which can effectively reduce the influence of the external photoelectric environment on the combiner box and prevent the combiner box and other components in the photovoltaic system from being damaged by external lightning strikes.
4. Temperature protection function: The PV AC combiner box is equipped with a thermometer or temperature controller to control the internal temperature of the PV AC combiner box, thereby ensuring the safe operation of electrical equipment.
5. Safety protection function: The PV AC combiner box is equipped with a safety protection device to monitor the operating status of the PV AC combiner box in real time to ensure the safe operation of the PV AC combiner box.
