MPPT solar charge controller MPPT solar charge controller 5. CHARGING LOGIC 5.2 Equalize Stage Equalization function is added into solar charge controller. It reverses the buildup ofnegative chemical effects 5.1 3-stage Charging like stratification, a condition where acid concentration isgreater at the bottom of the battery than at the top. In general, this solar charge controller is designed with 3-stage battery chargingalgorithm for fast, efficient, Equalization also helps to removesulfate crystals that might have built up on the plates.
MPPT solar charge controller MPPT solar charge controller 6. TROUBLE SHOOTING Equalize charging time and timeout In Equalize stage, based on maximum charging current of battery equalization, the controller will supply Situation solar power to charge battery as much as possible until battery voltage raises to battery equalization voltage. Situation Fault Then, constant-voltage regulation is applied to maintain battery voltage at the battery equalization voltage.
