Abstract: An energy generation system includes a plurality of energy generation devices for generating DC power, a plurality of energy storage devices for storing the generated DC power and discharging stored DC power, a plurality of single-phase inverters coupled to respective energy generation devices and energy storage devices. Each single-phase inverter of the plurality of single-phase inverters is configured to convert generated DC power or stored DC power to AC power so that the converted AC power of each single-phase inverter is offset by a phase from one another.

Abstract: An inverter includes a battery pack connection for supplying energy to or receiving energy from a photovoltaic string, a battery pack, an AC grid connection for supplying power to or receiving power from an AC grid, a connection for supplying power to a home back-up load, an electric vehicle connection for supplying to and receiving power from an electric vehicle (EV) battery, and a control input configured to receive one or more control signals for controlling the flow of power within the inverter. The inverter, under the control of the one or more control signals, converts power received from one of different power sources and provides the converted power to charge a battery of the EV.

Abstract: 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.
