What is the three-stage charging mode of the mppt solar controller?
1. Constant voltage equalization charging: The battery enters the constant voltage equalization charging stage when the battery is freely switched between the MPPT charging mode and the constant current charging mode. At 0.01C, this charging stage will stop and enter the float charging stage.
2. MPPT current-limited charging: When the voltage at the battery terminal is very small, use the MPPT charging method to draw the power of the solar photovoltaic panel to the battery terminal. When the light intensity is strong, the power of the solar photovoltaic panel increases, and the charging current reaches the threshold, then stop MPPT Charging is switched to constant current charging; when the light intensity weakens, it will switch to MPPT charging mode.
3. Constant voltage floating charge: Float charge the battery at a voltage slightly lower than constant voltage charging. This stage is mainly used to supplement the kinetic energy consumed by the battery self-discharge.
