2 Chapter I Overview
AC distribution unit. It operates in different modes according to the need.
The storage inverter plays a core role in the whole system and is characterized with high conversion efficiency, wide range
input voltage, rapid on/off-grid switching and convenient maintenance. It has a complete protection function (such as islanding
protection, DC overvoltage protection, AC overvoltage-under-voltage protection, over-frequency/under-frequency protection,
inverted sequence protection and output overload protection) and can meet on/off-grid operation requirements. The input side
of the storage inverter can be 1-Sting Configuration, 4-Sting Configuration and 8-Sting Configuration.
