Solar charge controller basic functions

Understanding the role of the solar charge controller in the overall PV system and the basic capabilities it has are a great help in choosing a solar charge controller and understanding how the entire PV system works.

一: The role of solar controller

The most basic role of solar smart controller is to protect the battery from overcharge or over discharge. Overcharging can cause the electrolyte in the battery to vaporize, causing problems, while over-discharging the battery can cause the battery to fail prematurely.

二: solar controller basic functions:

1, Overcharge protection: when the charging voltage is higher than the maintenance voltage, the battery is shut off voluntarily when the voltage is dropped to the holding voltage. When the voltage is lower than the recovery voltage, the battery is flooded and closed, and the battery is fully charged .

2, over-discharge maintenance: When the battery voltage is lower than the maintenance voltage, the controller will automatically shut down the output to protect the battery from damage; when the battery is recharged, but also take the initiative to recover power supply.

3, the load over-current and short-circuit maintenance: Load current exceeds 10A or load short-circuit, the fuse blown, the replacement can be continued use.

4, over-voltage maintenance: When the voltage is too high, take the initiative to close the output, to maintain electrical appliances from damage.

5, with anti-anti-charge function: the use of Schottky diodes to prevent the battery to the solar battery.

6, with anti-lightning function: When the lightning show time, varistor to prevent lightning strikes, maintenance manipulator from damage.
