APPARATUS AND METHOD FOR MANAGING AND CONDITIONING PHOTOVOLTAIC POWER HARVESTING SYSTEMS

摘要

The efficiency of a PV power generation system (10) is maximised by an apparatus providing series of electronic units (20) connected to the PV modules (12) and comprising microprocessor controlled DC converters/power supply units. A managing unit (60) communicates with the electronic units (20) of a string (11) in order to carry out a synergic optimization of the efficiency both of the single PV modules (12) and of the entire string (11). The apparatus also provides PV module (12) by PV module (12) diagnostic features and it is able to communicate with external devices for a full system control.
