In rural electrification the PV system plays an important role. Due to high costs in individual PV battery structures and large number of available lunar charge controllers it is important to select a suitable controller for each application. The overall system power flow is regulated by the special control unit is that charge controllers. This solar battery charger has normalize the potential difference and current flows in house-hold applications, multiple energy sources and converters which converts DC electric charge into AC. Several topologies dominate the world market. The solar charge controller has to protect the battery to charge it too much and avoid discharging with bottom value by using the low voltage and high voltage disconnection (LVD&HVD). In addition to this a charge regulator should have to monitoring the battery status. The state of charge calculation of this solar PV charge controller is good and it provides better battery management. The charge controller of solar PV system consists of shunt and series charge controller. A new technology based solar PV system controller is discussed in this paper. This controller is developed using MATLAB/SIMULINK.

“…Over the years, various control strategies for solar battery chargers have been proposed, most of them being based on conventional techniques. They generally use a classical MPPT algorithm, a linear closed-loop control, or a combination of both, as shown in [40,[42][43][44][45][46][47][48][49][50]. Conventional MPPT techniques fail under rapid atmospheric changes, which affect its performance.…”

This paper presents the design and implementation of a digital control strategy for a Buck converter, used as a solar charger of valve-regulated lead acid (VRLA) batteries. The control system consists of two fuzzy logic controllers (FLCs), which adjust the appropriate increment of the converter duty cycle based on battery state of charge according to a three-stage charging scheme. One FLC works as a maximum power point tracker (FLC-MPPT), while the other regulates the battery voltage (FLC-VR). This approach of using two different set of membership functions overcomes the limitations of the battery chargers with a single control function, where the voltage supplied to the battery is either not constant due to the operation of the MPPT algorithm (possibly damaging the battery) or is constant due to the operation of the voltage control (hence, MPP cannot be achieved). In this way, the proposed control approach has the advantage of extracting the maximum energy of the PV panel, preventing battery damage caused by variable MPPT voltage, thereby extending the battery’s lifetime. Moreover, it allows overcoming of the drawbacks of the conventional solar chargers, which become slow or inaccurate during abrupt changes in weather conditions. The strategy is developed to be implemented in a low-cost AT91SAM3X8E Arduino Due microcontroller. Simulations by MATLAB/Simulink and experimental results from hardware implementation are provided and discussed, which validate the reliability and robustness of the control strategy.
