2.3.1 Schematic Diagram
DC side: 4 PV strings are connected to the DC input terminals of the product. After
passing through the arc fault detectors, the DC output terminals of the product are
connected to the input terminals of the inverter.
AC side: The output terminals of the inverter are connected to the AC input
terminals of the product, and after passing through the AC relay, the AC output
terminals of the product are connected to the input terminals of the grid.
