DC Combiner Box
Description:
DC 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 DC Combiner Box provides a convenient means of accessing the DC portion of a PV system for routine maintenance and troubleshooting.
The PV array lightning protection box has the following characteristics:
(1) meet the requirements of outdoor installation, protection class IP65, with anti-UV, anti-acid, anti-alkali, moisture, mildew, rodent control and other functions;
(2) access 16-way PV array, each with 15A, 1000Vdc fuse (replaceable other grades);
(3) Equipped with special high-voltage lightning protection device, lightning protection function with cathode and anode ;
(4) Positive, negative string into the fuse;
(5) Use quadruple PV dedicated circuit breaker with positive and negative in series
