1.Description:
For a large PV power generation system, In order to reduce the grid connection between the grid-connected inverter and the cabinet, it is convenient to maintain and improve reliability. It is necessary to add a DC bus between the PV grid-connected inverter and the cabinet. PV AC lightning protection combiner box series products of the company are specially designed to meet this requirement, Can be composed of PV inverter products matching with complete PV system solutions. Using the Ac combiner box, the user can according to the AC power cabinet rated input current and voltage, the output of a certain number of the grid-connected inverter by lightning protection device and circuit breaker for confluence, convenient access level power cabinet.
