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.

PV combiner box branch voltage

Common rated voltages for combiner boxes are 600V, 1000V, and 1500V. Notes when selecting: Do not operate under overvoltage for extended periods, otherwise it will reduce device lifespan or even cause breakdown.
