39Duud/Zlwkvhyhudovwulqjvglylghglqwrvhyhudojurxsv: PV Array Box PV

This document discusses photovoltaic installations with multiple configurations. It describes a multi-string photovoltaic array connected to several single-phase inverters in a three-phase arrangement. For arrays over 50-100 kW, the arrays are divided into sub-groups with strings paralleled at two levels in sub-array boxes and a main array box near the inverter. Safety devices, monitoring equipment and load block switches are included in the design.
