Powerporter is a lithium-ion battery that can store electrical energy and outputs DC current. Powerporter only maintains electrical connection with the inverter. The electrical energy generated by the PV is converted by the inverter Dc to DC and stored in the connected Powerporter. When Powerporter is needed, Powerporter’s electrical energy is converted by the inverter DC to AC and transmitted to the home grid to provide power for household appliances.
(Note: The actual Residential ESS may also include electrical equipment such as distribution boxes and metering meters)
