Description:

Lighting  arresting DC distribution cabinet is mainly used for combine the Inverter  Output AC power; connect a series of photovoltaic inverters in parallel. The  output of distribution cabinet connects to the corresponding step-up input  wire, and it assembles with meter device inside. It mainly composed of Lightning  arrested module, measuring device, AC circuit breaker, etc.

All  accessories manufactured according to national standards accurately. Bolts,  nuts and other fasteners and mechanical tolerances in line with the relevant  provisions of national standards. Cabinet have been electrostatic painted,  anti-degreasing, rust or phosphate coated beforehand. The paint also complies  with national standards.
