4-24 Strings Solar Array Junction Box , Photovoltaic Combiner Box
Product description
For a large-scale grid-connected PV system, it is widespread to install a DC combining device between PV modules and inverters to minimize cable connections, facilitate maintenance and enhance reliability. IPKIS PV combiner box series (PVBOX) are designed for meeting these requirements, which provides a turnkey solution for PV plant systems. Considering different types of PVBOX, a certain number of PV strings can be connected to the input side of IPPVS. After combining work done, at the output side, there will be one DC+ and one DC- main line. By using of surge protection device (SPD) and circuit breakers, the output can be connected inverters directly.
