WSDB-PV1/1 IP65 1/2/3/4/ in 1/2/3/4/ OUT 1/2/3/4 Strings Array 16A 500V 1000V 1500V DC Solar PV Combiner Box for Solar System

SOLAR BOX Application

Combiner Box provides a means of combining multiple source circuits from a PV array into a single DC output. Each source circuit is fused separately using a touch-safe fuse holder. The combiner box allows for fail-safe operation of the system in the unlikely event that a problem with a source circuit leads to abnormally high current. In addition, the combiner box provides a convenient means of accessing the DC portion of a PV system for routine maintenance and troubleshooting.
