Photovoltaic (PV) power systems at the moment, are the most important renewable sources that can be used for electric power generation. This system always contains storage batteries, which represent one of the most important elements. The battery bank storage the electrical energy generated from the solar cells during the day to use it at another time especially in the night. This paper proposes and implements smart charge/discharge controller to increase lifetime and improve the performance of storage batteries. The proposed regulator is designed with two functions. The first function is to regulate the battery voltage within specific range of 11V to 15V. The second function is to control the load operation during the time between the sunrise and sunset. The proposed smart regulator is designed based upon microcomputer or microcontroller (PIC). The PIC is programmed according to a definite strategy. Two strategies are design. One of which is required for charging and discharging the lead-acid battery connected with the PV system. On the other hand, the second strategy is programmed according to the operation procedure of the load connected with the system. The two strategies are programmed by using PIC language. |
