The PWM solar photovoltaic controller uses three-stage charging modes: balanced charge, strong charge, and floating charge.
1. Balanced charge: After the strong charge is completed, the battery will stand for a while until the voltage naturally falls to the corresponding value, and then it will enter the state of balanced charge, so that the voltage at the battery terminals is uniform and consistent.

2. Strong charging: also called direct charging, which means fast charging. When the battery voltage is low, the battery is charged with a large amount of current and a relatively high voltage.
3. Float charge: After the equalization charge is completed, the battery is left in the same static state for a while, and when the voltage naturally drops to the "maintenance voltage" point, that is to say, the float charge stage, so that the battery can be maintained in a fully charged state without overcharging.
