Can a solar panel be directly connected to a battery?Updated 2 years ago
It is not recommended to do so. Under appropriate conditions, panels with small wattage can directly charge the battery, However, the battery should not be left unattended. It should be disconnected manually when the battery is about to be fully charged, otherwise, there will be overcharging.
When charging a battery using a solar panel, it is highly recommended that you use a solar charge controller.
