The key function of a battery in a PV system is to provide power when other generating sourced are unavailable, and hence batteries in PV systems will experience continual charging and discharging cycles. All battery parameters are affected by battery charging and recharging cycle.
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.
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.
Under optimal conditions, a solar panel typically needs an average of five to eight hours to fully recharge a depleted solar battery. The time it takes to charge a solar battery from the electricity grid depends on several factors. The factors that influence the solar battery charging time are: 1.
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.
Using car battery chargers is another way to charge solar batteries, but it’s important to verify compatibility and match the specifications accordingly. Automatic car chargers are better for solar batteries because they avoid overcharging. So, a car battery charger, solar batteries is a good option for powering energy storage systems.
