Abstract

The outline of a new PV (photovoltaic) storage battery charge regulator is given. The novelty of this system consists in its working on electrolyte density so that the induced current provided by the PV generator is adjusted according to the actual state of charge. This device is fitted into a new hybrid experimental PV energy power supply system for both telecommunication systems and emergency DEG (diesel engine generator), which is operated in case of low battery capacity. The device has also been used to start and stop the DEG with better results than the ones provided by the system based on threshold values of the battery voltage.<>
