PV Combiner Box, manufactured by Yueqing Sandi Electric Co. has application for a large-scale PV system, it is common requirement to fit a DC combining device between PV modules and inverters in order to decrease the cable length between them, making maintenance easier and enhancing reliability. Having several years of PV grid-connected system manufacturing experience, our series of PV combiner box is fabricated in a way that can fulfil the requirement of higher performance and better reliability of PV Combiner Box. Being attached to our Solar Access inverters, Yueqing Sandi Electric Co. offers a turnkey and bespoke solutions for PV power plant systems. Through utilizing PV array combiner box, in agreement with the input voltage of the inverter, Users can add a specified number of similar PV modules to produce a PV array.Subsequently, distinct strings of PV array is combined into the PV array string box. then, along with lightning arrester and circuit breaker, it is added to the inverter for minimizing the system installation time and maximizing the system safety.
