Here's a simplified explanation of how a solar battery charger works:
1. Sunlight strikes the solar panels.
2. The solar panels convert the sunlight into direct current (DC) electricity.
3. The DC electricity is sent to the charge controller.
4. The charge controller regulates the voltage and current to prevent overcharging of the battery.
5. The regulated electricity is then used to charge the battery.
6. The charged battery can be used to power devices by connecting them to the charger's output ports.
Solar battery chargers can vary in size and power capacity. Smaller chargers are often portable and designed for charging small devices like phones and tablets. Larger chargers may be used for charging larger batteries, such as those in recreational vehicles (RVs) or boats.
