Regulator to charge a 12v battery. Use a 16v panel (25-28 cells). Consider is the wattage of the panel. It controls how fast battery charges. A 12v 1.2A/h batt has 14w-hours of energy. A 6w panel (16v-18v) gives 18w-hours (in bright sunlight) in 3 hrs. The battery charge in 3 hrs. Adjust pot so relay drops out at 13.7v Charger turns ON when the v drops to about 12.5v. The 100R Dummy LOAD will absorb 3.25 watts and that is the maximum wattage the panel will produce with 100R load.
This is a simple battery charge level indicator circuit and is very useful to calibrate inverter status, to measure car battery level, etc.
Here is the simple solar battery charger circuit designed to charge a 5 - 14v battery using LM317 voltage regulator. It is very simple and inexpensive.
