Abstract

See full text

A string inverter for use with a photovoltaic array includes at least one string-level DC input channel for receiving DC power from the photovoltaic array, and at least one input-output channel for connecting the string inverter to a battery pack. The string inverter also includes a DC to AC inverter having an AC output, and a switch configured to control a flow of power through the string inverter. When the switch is in a first state, AC power can flow from the string inverter to a load side of a customer utility meter and one or more back-up loads, in a second state, power can flow from the load side of a customer utility meter to the one or more back-up loads bypassing the string inverter, and in a third state, all circuits coupled to the output of the string inverter are electrically disconnected from the string inverter.
