PV Combiner Box Intelligent Monitoring Device
Summary:
Sandi PVB series PV Combiner Box is used for the connected of PV inverter and PV array to lessen the cable for the connecting, easy to maintain and improve the reliability. We always fix the DC convergence device between the PV inverter and PV array. With many years of experience in the PV power system, it is specially designed for the high efficiency and reliability; it is the supporting components of our PV inverter for the PV power generating. You could connect a certain number of PV components in series to be the PV array according to thevoltage range of DC input; then connect the PV array to PV lighting protection combiner box for the converge, through the output of lightning protection device and breaker, it is easy for switching-in of PV inverter and improve the system safety and lessen the installing time.
Features of PV array combiner box:
- Applicable for outdoor PV systems;
- 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;
- Protection class IP65 for outdoor use;
- Output Waterproof terminals;
- Wall mounting type is easy to installation
- RS485 remote monitoring
