Solar charge controller charge and discharge protection

The main function of the solar charge controller in a solar photovoltaic system is to prevent overcharging of the battery pack and excessive discharge of the battery by the battery. In order for the system to work continuously and consistently, the battery pack must be operated within the specified specifications.

Solar Charge and Discharge Controller: In order to protect the battery, to prevent charging and overcharge, over-discharge protection, in most solar power systems include solar charge controller, the main is to cut off the charge current when the battery is full, As a result of a variety of battery charging characteristics are not the same, so we should choose according to the battery type of solar controller.

Solar controller charge and discharge protection

1. Direct charge protection point voltage: direct charge also called emergency charge, are fast charge, usually when the battery voltage is low with high current and relatively high voltage on the battery charge.

2. Charge control point voltage: After the direct charge, charge and discharge controller will put the battery for a period of time, let the voltage drop, when falling to the "recovery voltage" value, it will enter the state of charge.

3. Float charge control point voltage: After the charge is completed, the battery is also allowed to stand for a period of time, so that the voltage drops naturally, when the drop to the "maintenance voltage" point, enter the floating state.

4.Over-discharge protection: This is better understood. Battery discharge can not be lower than this value, which is the national standard.
