Betjeningsvejledning

Once installed and wired correctly, the PV Combiner Box operates automatically to combine and protect your solar strings. The internal components provide overvoltage, overstrøms- og kortslutningsbeskyttelse.

Betjening af maksimalafbryder

The 63A circuit breaker provides overvoltage and overcurrent protection. In case of a fault, the breaker will trip, disconnecting the load circuit. To reset, identify and resolve the fault, then push the breaker switch back to the 'ON' position.
