Strings DC Combination Lock Box Solar PV Combiner Box 4-24strings

OEM Wall Mounted Solar Power System PV Junction Box Solar Array PV String Box

    For large-scale PV grid connected power generation power system, in order to reduce the connecting lines between PV modules and inverter, easy maintenance and  improve the reliability, generally it needs to increase the DC bus system between photovoltaic modules and inverter. This PV combiner box is specially designed to meet this requirement, it can match with inverter products to compose complete PV system solution. DK-PV series PV combiner box, there are surge protective device(SPD)in the output terminal, which can protect the DC fuse cutout of the PV combiner box, inverter and other terminal equipments, to ensure the whole PV power generation system operate long-term and steadily.

     PV Power Generation System with PV Lightning Protection Combiner Box is as follow:

Main Function

  1. Simultaneously access multipath solar power photovoltaic array, rated current of each line can reach 10A, IMax 15A, which can meet the requirements of different clients.

  2. Equipped with DC fuse cutout in each input line  to avoid system damage from over-current, make sure the system can operate steadily.

  3. Equipped with DC high voltage lightning protection module in the output terminal, which can tolerate Max40kA lightning current.

  4. Adopt high voltage breaker, the DC withstand voltage is not lower than DC1000V, safe and reliable.

  5. With high power anti-reflaction device, which can avoid the countercurrent flowing backward due to the malfunction.

  6. Protection level is IP65, which meets the using requirement of outdoor installation.
