AbstractThere is much work currently in the field of renewable energy, particularly, solar energy to replace the traditional energy sources. In this paper, a solar charge control system has been designed with voltages of 24 V and 12 V and current capacity of 220 A. The design procedure is firstly set-up by adjusting the input voltage delivered from solar cells during the period (7 a.m.–5 p.m.) for maximum sun rise.
To assess the robustness of the designed circuit, the circuit has been simulated under different input voltages and external load conditions. The first test is verified by changing the input voltage supplied from the PV solar panel with the same voltage change during the test period. The results showed that the output voltage has remained at constant level. The other test is performed by changing the output load value such that it reaches approximately the load of batteries. It has shown that no change in total currents occurs. This could prove that the design technique give both stable and robust performance. Moreover, the designed charge controller can successfully deliver a charge power of 2KW. This power is considerably high when compared with other circuits.
The design of the charge control system is based on simulated results and it has been verified using PSpice.
