State three factors considered when sizing a charge controller?

1. Solar panel voltage and current: The charge controller must be able to handle the maximum voltage and current output of the solar panels to ensure efficient charging of the battery.

2. Battery voltage and capacity: The charge controller must be compatible with the voltage and capacity of the battery to prevent overcharging or undercharging, which can reduce the lifespan of the battery.

3. System voltage: The charge controller must be able to handle the voltage of the entire solar power system, including the solar panels, battery, and any other components, to ensure safe and efficient operation.
