A schematic diagram of the solar battery charging circuit. The battery is charged when the voltage of the solar panel is greater than the voltage of the battery. The charging current will decrease as the battery gets closer to being fully charged. This is just a simple circuit, and there are many other ways to charge a battery from solar power.
When Bulk Charging is complete and the battery is about 80% to 90% charged, absorption charging is applied. During Absorption Charging, constant-voltage regulation is applied but the current is reduced as the solar batteries approach a full state of charge. This prevents heating and excessive battery gassing.
During bulk charging for solar, the battery’s voltage increases to about 14.5 volts for a nominal 12-volt battery. When Bulk Charging is complete and the battery is about 80% to 90% charged, absorption charging is applied.
Solar charge controllers put batteries through 4 charging stages: What are the 4 Solar Battery Charging Stages? For lead-acid batteries, the initial bulk charging stage delivers the maximum allowable current into the solar battery to bring it up to a state of charge of approximately 80 to 90%.
The solar to battery charging efficiency was 8.5%, which was nearly the same as the solar cell efficiency, leading to potential loss-free energy transfer to the battery.
At higher constant charging current rates the battery charges more effectively and this does not only apply to the Vanbo Battery (battery Sample 01) that was tested before but it was also true for the Winbright battery (battery sample 02) tested too.
Furthermore, with the advent of hybrid solar charge controllers, which can handle inputs from both solar panels and AC sources like the grid or a generator, the …
