The evolution of a handful of PV-Battery charge controller systems has been studied in the literature, particularly in recent years. The focus of this topic is inspired by the ever-increasing demand for trusted charge controller techniques (Othman, 2020; Tan et al., 2020; Chtita et al., 2021).
The main objective as well as the unique feature of the proposed control strategy is to instantaneously balance the PV power flow delivered to the DC load and the battery, so that the PV power is effectively utilized and the battery is properly charged.
In off-grid photovoltaic (PV) systems, a battery charge controller is required for energy storage. However, due to unstable weather conditions as well as the frequent variations in load demand, the PV power flow delivered to the load could be fluctuated while the battery charging efficiency will be reduced.
As can be seen from this figure, the waveforms of the PV power, PV voltage, and PV current successfully correspond to their theoretical MPP values, while the battery current waveform corresponds to a positive value of 4 A, indicating that the battery is being charged by the excessive power (i.e., P MPP - P R ).
