A combiner box is a key DC distribution device used between PV strings and the inverter. Each string consists of solar modules wired in series, and the combiner box gathers multiple strings into a single output while ensuring safety and system efficiency.
The combiner box is responsible for combining multiple strings of solar panels into a single circuit, which then connects to the inverter. This wiring diagram will guide you in understanding how to properly wire a PV combiner box.
The input current of a smart combiner box can be measured by isolated and non-isolated current sensing methods depending on the accuracy, size, and cost restrictions. Isolated solutions are widely used in smart combiner boxes.
