4 strings PV Array outdoor PV system Combiner Box
For large scale grid-connected PV systems, a DC combining device will be installed in between the PV arrays and the inverters to minimize the cable length, increase the reliability and stability, and also for the ease of maintenance. Multifit PV Array Combiner Box is a standardized product developed to use with solar power system to provide a turnkey solution for PV power plants. Based on the DC input voltage range of the inverter, a quantity of the same PV strings can be connected to form a PV array. Then different PV arrays can input into the PV array combiner box, which including lightning protection devices and circuit breakers, to output a DC current for the inverter connection.
Features of pv array combiner box:
·Applicable for outdoor PV systems
·4/6/8/10/12/16 PV string inputs with maximum string current at 20A
·Wide DC voltage input range with maximum open-circuit voltage up to 1000V
·With PV dedicated DC fuses with maximum voltage not less than 1000V
·With PV dedicated high voltage lightning protection device
·Both +ve & -ve poles equipped with a 4-pole circuit breaker with the allowable DC voltage not less than 1000V
·Monitoring feature optional for each string of PV array
·Waterproof terminals
·Lighting Protection
