Description

———— Product Features ————

  • A grid‑connected photovoltaic power generation system comprises solar cell modules, a simulated combiner box, a DC distribution cabinet, a grid‑connected PV inverter, an AC step‑up transformer, and metering equipment. Solar energy is converted into direct current by the solar cell modules, then collected via a lightning‑protection combiner box before being routed to the DC distribution cabinet. The DC distribution cabinet performs secondary string‑level combining of the DC cables from multiple combiner boxes and subsequently distributes the combined output to the grid‑connected inverter. The inverter converts the DC power into AC power and feeds it into the utility grid. In large‑scale grid‑connected systems, the DC distribution cabinet primarily handles the secondary string‑level combining of multiple DC inputs.
