Solar DC Junction Box PV Combiner Box with 4 Strings Metal Waterproof Electrical Boxes IP65

PV combiner box in the solar pump system

1. In the solar power system, in order to decrease the connecting line, easy maintenance, reduce losses, optimize system structure, improving the safety and reliability of items, the PV combiner box is usually in need between the solar panels and inverter.

2. Except the PV junction function, the pc combiner box should also have reverse current prevention, over-current protection, over-voltage protection, lightning protection etc a series of perfect protection functions, meanwhile, checking the running state, current, voltage and power after junction, arrester state, collection of DC circuit breaker state and Arc detection,leakage detection(optional) and so on.

3. The PV combiner box we manufacture is equipped with all the functions mentioned above, configuration with on grid/off grid solar inverter to make up a complete set of solar power system.

4. When choose the pv combiner box, based on the input dc voltage range and output power of inverter, certain qty of panels will be connected in series as a string, certain strings in parallel will connect to the PV combiner box for junction, via control of circuit breaker and protection of arrester, then feed to the inverter.
