The JUER Electric® DC Solar System Array String Combiner Box which is of low price and provides free sample to a junction box, which is an electrical enclosure that securely unites multiple wires and cables through various ports of entry. A solar combiner box combines the output of numerous strings of PV modules for connection to the inverter.
The JUER Electric® DC Solar System Array String Combiner Box With overall protection such as counterattack prevention, overcurrent protection, overvoltage protection and lightning prevention, PV combiner boxes are used to reduce the connecting wires between a PV module and an inverter or controller, make maintenance easy,reduce the loss and improve product safety and reliability. The PV combiner box produced by us has all the functions above and provides users with a complete solution for PV power generation systems.
1）Two groups of independent PV array input and output for flexible application in different connection schemes;
2) Multiple PV input arrays each of which has a maximum current of 10A;
3) A high voltage fuse provided for the counterattack prevention of each PV input array;
4) A special high-voltage lightning protection device for the PV module;
5) A special high-voltage circuit breaker for output control of the PV module;
6) A degree of protection of IP65 for meeting the need of outdoor installation.
