Solar Panel 1000V DC Combiner Box Array 4mm2 For Distribution Box Indoors

Residential use PV junction box? with SPD piezo resistor protection ,both positive and negative poles have fuse protection ,Residential use solar panel junction box,small home use PV Module combiner boxes 14 strings

Quick Detail:

It is mainly used for combine of strings in home solar systems, installed beside the distribution box indoors.

Key features:

1,String input adopts independent circuit breaker controls in each group, each group of strings has counter-attack diodes to prevent circulation.

2,Adopts Class II Overvoltage Protection Group to protect positive and negative terminals thus creating high security, reliability and excellent protection function.

3,Designed with small size and easy to install features

.Description:

The combiner box is a device that combines the output of multiple strings of PV modules for connection to the inverter. It is typically used in the larger commercial and utility scale PV power plants (greater than 50kW). The combiner box commonly houses the input overcurrent protection fuse assemblies for several strings (from as few as 2 strings to as many as 32), as well as the combined bus of those inputs into a single main output.

Normally PV combiner box may also house several other components for the site, such as a DC disconnect, surge protective devices and string monitoring hardware.
