Solar Power System Used PV combiner box with IP65

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.

Description
PV combiner box is accustomed to unite the yield DC power of the PV range. It will consolidate the same sun based boards, which in arrangement to shape a PV range, reinforcing the utilization of photovoltaic lattice associated inverter, in order to constitute an entire photovoltaic system alongside the city electric matrix.

Elements of PV Combiner Box:
  • Relevant for outside PV systems
  • Every PV connected to DC combine assurance and anti-back safety discretionary
  • Broad DC current input extend with greatest open-circuit current up to 1000V
  • High current lightning security (SPD) exceptional for PV
  • PG wire glands connection input, safe system wiring and advantageous
  • PV extraordinary high current electrical switch regulation output
  • Safety class IP65 for outside usage
  • Output water safe terminals
