PV combiner box is used to bring together the output DC current of the PV array. It will combine the same solar panels which in series to form a PV Array ,supporting the use of photovoltaic grid-connected inverter, so as to constitute a complete photovoltaic system, with the city electric grid.

Summarize

PVB series PV Array Combiner For a large-scale grid-connected PV system, it is a general practice to install a DC combining device in between the PV modules and inverters for the sake of minimizing the cable distance between them, facilitating maintenance and improving reliability. With many years of PV grid-connected system design experience, our PVB PV array combiner box series is specially-designed for meeting the need of high performance and high reliability of PV systems. In combining with our Solar Access inverters, Sandi PVB provides a turnkey solution for PV power plant systems. 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.

Features of PV array combiner box:

* Applicable for outdoor PV systems;

* Each PV array attached to DC fuse 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;

* Protection class IP65 for outdoor use;

* Output Waterproof terminals;
