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.
Main function:
1. It can be connected to multiple solar photovoltaic arrays at the same time, each with a rated current of up to 10A and a maximum of 15A, which can meet the needs of different users;
2. Each input is independently equipped with solar photovoltaic DC high voltage lightning protection circuit, with multi-level lightning protection function to ensure that lightning strikes do not affect the normal output of the photovoltaic array;
3. The output terminal is equipped with a photovoltaic DC high-voltage lightning protection module, which can withstand a maximum lightning current of 80kA.
4. Using high-voltage circuit breakers, the DC withstand voltage value is not less than DC1000V, safe and reliable;
5. With lightning recording function, it is convenient to understand the intrusion of lightning disasters;
6. With real-time display function of current, voltage and power, it is convenient to observe the working status;
7. The protection level reaches IP65, which meets the requirements of outdoor installation;
8. With remote monitoring function (optional).
