Smart Combiner Box

Solar Energy - Smart Combiner Box


For photovoltaic (PV) arrays with a power capacity greater than 50 kW, it is necessary to combine the PV strings into a high voltage Direct Current (DC) bus before the inverter. This system is known as a solar combiner box. The solar combiner box became smart when current and voltage sensing technology was moved from the solar inverter (multi-string level) to the combiner box in order to immediately detect a solar panel operating at diminished capacity and the corresponding damage. Smart combiner boxes are also being enriched with additional features, including:
