The solar power system, array junction box has smart and non-smart two types. The smart lightning-protection pv combiner box has built-in combiner monitoring unit that monitors the input voltage of each PV string, collective output voltage, temperature inside the box, as well as the status of lightning protector and circuit breaker, etc. We also supply PV Intelligent Lightning Protection array junction box.

Our combiner box has above function, and also could match with PV grid tie inverter and off grid inverter to compose one complete PV generating system.
When choosing PV combiner box, user could connect solar panels in parallel or in series to place in combiner box according to inverter’s input voltage range, output power, then go through breaker and surge protection to work with inverter.
