Solar charge voltage regulators should coordinate the charging process of a battery. Suppose that I would like to design a very basic charging regulator controller with the following specs:
The battery charged is a 12V 12Ah lead acid battery.
The power supply is a 12V 10W solar panel.
During the day the battery is not used.
What are the minimum requirements and specs that are required? At the top of my mind I thought of the following:
- Over voltage protection (the charging should stop when Vbattery > Vmax)
- Over current protection (the current should be less than the maximum allowable by the battery) but this seems not to be an issue since the PV module is just 10W 12V.
If you need a battery for reference, then just take this one.
