Abstract

Charge controller is the device which is connected between the photovoltaic (PV) modules, DC batteries and loads. This paper proposes the design and implementation of a charge controller which is capable to protect the lead acid batteries in the PV system from overcharge and undercharge states. Moreover, this charge controller is designed to make the battery voltage near the PV voltage at the maximum power point (MPP) for the PV modules. Also, the designed charge controller uses the fuzzy logic Pulse Width Modulation (PWM) control, in order to make use of the full capacity of the lead acid batteries in the system. Therefore, this proposed design improves the reliability of the PV system and reduces its total cost.
