14 Strings 1000 VDC PV Combiner Box for Solar Panel Confluence Box Array System

Product Description

14 Strings 1000 VDC PV Combiner Box for Solar Panel Confluence Box Array System

By using PV array combiner box, according to the input voltage of the inverter, Clients can connect a fixed number of similar  PV modules to form a PV array. Then different strings of PV array can be converged into the PV array string box. After that, together with lightning arresters and circuit breakers, it is connecting to the inverter to reduce the system installation time and increase the system safety. Each PV array attached to DC fused protection and anti-reverse protection optional. Wide DC voltage input range with maximum open-circuit voltage up to 1000V. High voltage Lightning protection (SPD) special for PV. PG cable glands connector input, convenient and safe system wiring. PV special high voltage circuit breaker control output.

Our PV Combiner Box is known for high-quality construction, versatility, safety features, easy installation, and high-quality components.
