Power Quality of Pv Inverters, Related To Topology And Control

Abstract

The Shunt Controller allows two circuits to be temporally isolated from an active security system. The unit has two alarm inputs and each one is monitored by a 2K2 resistor. If this input is either open circuit or closed circuit the input is considered to be in alarm. Similarly the set input is also monitored by a 2K2 resistor. The set input controls the isolation of the other two inputs.
