What Is a PV Combiner Box?
A PV combiner box is a device designed to facilitate efficient transmission of direct current (DC) power collected from solar panels.
It receives DC power from solar panels, combines it into one or multiple strings within the PV combiner box, and sends it to wiring or inverters.
Widely used in solar power plants and residential solar energy systems, the PV combiner box plays a crucial role in efficiently transmitting DC power from solar panels to transmission lines. Its structure includes basic components from DC input terminals to DC output terminals, as well as protective circuits to detect overcurrents short circuits for circuit protection, and monitoring circuits to monitor electrical information. Its features include simplifying the wiring of aggregated DC power and effectively protecting DC circuits.
