Solar Controller is the core of solar power generation system, and its main use to protect the battery charge and discharge normal, the following fine energy to tell you the specific said this charge and discharge protection function.
Solar Charging controller: In order to protect the battery charge and discharge normal, is when the battery is full to cut off the charging current, because the charging characteristics of various batteries are not the same, so we should choose the solar controller according to the type of battery.
1, Direct charge protection: Direct charge is also called sharp charge, belongs to the fast charge, is generally in the battery voltage is low when the battery charge with high current and relative height voltage.
2, all charge protection: After the end of the direct charge, the charging and discharging controller will rest the battery for a period of time, so that its voltage natural fall, when falling to the "recovery voltage" value, will enter the full charge state.
3, floating charge protection: generally after the full charge, the battery is also static for a period of time, so that its end voltage natural fall, when falling to the "maintenance voltage" point, into the floating charge state. 4, Release protection: This is better understanding. Battery discharge can not be lower than this value, which is the standard of the GB.
