View the Complete Application at the US Patent & Trademark Office
A dispatchable photovoltaic (PV) panel product that includes multiple types of voltage sources is described. The product can include a PV panel that includes PV cells, a battery, and a panel level panel mounted inverter coupled to the PV panel and the battery. Each of the battery and the PV panel are to generate direct current (DC) power. The panel level inverter is to convert the DC power into alternating current (AC) power and discharge the AC power to an electrical load. The panel level inverter can include a voltage source interface converter (VSIC) for charging or discharging the battery using a charge/discharge profile for the battery. The panel level inverter can also include a voltage source monitoring/protection system to (i) protect the battery from damage; and (ii) monitor at least one of a condition of the battery or a condition of the PV panel.
