XZPV-DC32 lightning protection combiner box combines up to 32 DC input combiners of photovoltaic cell modules into one or multiple outputs, each fitted with a fuse, and the output is equipped with lightning protection devices and circuit breakers, thus greatly simplifying the input wiring of DC distribution cabinets and inverters. Provide lightning protection, short circuit protection, and grounding protection. The combiner box is divided into two types: intelligent and non-intelligent. Inside of the former there is equipped with a current monitoring unit, which can monitor the input current of each photovoltaic cell string, summarize the output voltage, the temperature inside the box, the status of the lightning arrester and the circuit breaker.
