1. Box
The protection grade is above IP 65, waterproof and dustproof , and meet the requirements of long-term outdoor use.
2. DC circuit breaker
DC circuit breaker is a PV combiner box output control device, used for circuit opening and closing. Its working voltage is as high as DC1000V. Since the power source generated by the solar cell module is direct current, it is prone to arc when the circuit is broken. Therefore, when choosing a PV combiner box, the temperature and altitude derating factors of the PV combiner box should be fully considered, and a dedicated PV DC circuit breaker must be selected.
3. DC fuse
When the PV combiner box has reverse current, the photovoltaic special DC fuse can cut off the faulty string in time. The rated working voltage is DC1000V, and the rated current is 16A (crystalline silicon module). PV modules use DC fuses which are specially designed for photovoltaic systems. It is installed on a special enclosed base to prevent current from flowing back between the strings and burning the module. When the PV combiner box has current return, the DC fuse will quickly withdraw the faulty string from the system operation without affecting other strings that are working normally. It can safely protect PV strings and conductors from the threat of reverse overload current.
4. Anti-reverse diode
The role of diodes in PV combiner boxes is different from that of diodes in module junction boxes.
