Product Description

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.

Summarize

PV range combiner for vast scale matrix associated PV system, it is normal practice to introduce a DC consolidating instrument in the middle of the inverter and PV modules for limiting the link remove between them, encouraging handling and enhancing unwavering quality. With numerous times of PV matrix associated system configuration encounter, our PV combiner box is exceptionally intended for satisfying the requirement of high reliability as well as high performance of PV systems. By utilizing PV combiner box, as per the input current of the inverter, customers can associate a settled number of comparative PV modules to frame a PV array. Further, distinctive strings of PV can be met into PV string box. From that point forward, together with circuit breakers and flash arresters, it is associating with the inverter to diminish the system introduction time and enhance the system protection.

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
