Abstract
A photo-voltaic (PV) power generating system and a control system for PV array string-level control and PV modules serially-connected into strings of PV modules. The system includes plural parallel strings of serially-connected power-generating photovoltaic modules that form a PV array, DC/DC micro-converters that are coupled to a DC voltage buss and to the output of a corresponding photovoltaic module or to the output of a string of photovoltaic modules; a gating or central inverter; and a control system. The control system is structured and arranged to control and manage each string of photovoltaic modules, to ensure that power delivered by the photovoltaic power generating system is not affected by photovoltaic modules or strings of photovoltaic modules that are not operating at maximum power transfer efficiency.
