When the communication line is short-circuited, all the combiner boxes in the entire array cannot communicate, and the RS485 communication voltage of the combiner box module is zero. Solution: Disconnect all the communication lines of the combiner boxes in. . In solar photovoltaic (PV) power generation systems, the solar combiner box is a crucial electrical device on the DC side. Failure can stem from wiring faults, fuse issues, poor grounding, or even weather. Here's how to troubleshoot and maintain it properly to keep your PV system operating safely and. . All the strings are producing the correct voltage, but once I flip my circuit breaker on in the combiner box, the lines drop from 160vdc to 2. 5v and the output to the inverter reads 1vdc. They trigger nuisance trips, hot spots, and hard-to-trace faults.
