Solar Charge Controller Protection Mode
Apr 13, 2018

   Direct charge protection point voltage: Direct charge is also called emergency charge, which belongs to fast charge. Usually when the battery voltage is low, the battery is charged with high current and relatively high voltage. However, there is a control point, also called protection point.Solar Charge Controller is the value in the above table. When the battery terminal voltage is higher than these protection values during charging, direct charging should be stopped. The direct charge protection point voltage is generally also the "overcharge protection point" voltage, and the battery terminal voltage cannot be higher than this protection point during charging, otherwise it will cause overcharge and damage the battery.

   Equal charge control point voltage: After the direct charge is completed, the battery is generally left standing for a period of time by the charge and discharge controller, allowing the voltage to fall naturally. When it falls to the “recovery voltage” value,Solar Charge Controller will enter the equal charge state. Why do you have to design the charge even if the battery is "backward" (the voltage of the terminal is relatively low) after the direct charge is completed, and in order to pull these individual molecules back and make all the battery voltages have a uniform consistency, it is necessary to With a high voltage coupled with a moderate current and then recharging for a small amount of time, it can be seen that the so-called equal charge, that is, "balanced charge." The average filling time should not be too long, usually a few minutes to ten minutes, but the time setting is too long to be harmful. For a small system equipped with a two-battery battery, it is not meaningful. Therefore, street light controllers generally do not have equal charge. There are only two stages.
