Abstract
Provided is a system and method for detecting and correcting a suboptimal operation of one or more maximum power point tracking (MPPT) devices in a solar photovoltaic power generation (SPVPG) system. MPPT devices may become stuck in a local maximum in a power curve and fail to reach an optimal maximum power point. Described herein are methods and systems for detecting sub-optimal performance of an MPPT device and managing components within the SPVPG system to cause the MPPT device to track a different maximum power point.
