Title: PHOTOVOLTAIC SYSTEMS WITH LOCAL MAXIMUM POWER POINT TRACKING PREVENTION AND METHODS FOR OPERATING SAME
Abstract:
A photovoltaic system (110) includes solar cells (115) and an inverter (120) configured to convert direct current generated by the solar cells (115) to alternating current. The photovoltaic system (100) includes a maximum power point (MPP) tracking module (122) configured to perform MPP tracking for the photovoltaic system (100). The MPP tracking module (122) is configured to detect shading of the solar cells (115) and to modify its MPP tracking to prevent tracking of local MPPs. The MPP tracking module (122) may be incorporated in the inverter (120).
