Abstract

A method for providing a maximum power point tracking (MPPT) process for an energy generating device (202) is provided. The method includes coupling a local converter (204) to the energy generating device (202). A determination is made regarding whether the local converter (204) is operating at or below a maximum acceptable temperature. A determination is made regarding whether at least one current associated with the local converter (204) is acceptable. When the local converter (204) is determined to be operating at or below the maximum acceptable temperature and when the at least one current associated with the local converter (204) is determined to be acceptable, the MPPT process is enabled within the local converter (204).
