Charging Valve Regulated AGM Batteries

mars 30, 2017

Did you know that the new ProStar Gen3 solar charge controller is equipped with DIP Switches (switch #’s 4, 5 and 6) that enable seven preset charge configurations and a custom setting to best meet the charging requirements for valve regulated AGM lead acid batteries? Higher Voltage Equalization charging, commonly used with Flooded batteries, can be harmful to valve regulated AGM batteries.  To avoid this problem, auto-equalize options can be disabled for the ProStar Gen3 solar charge controller by switching DIP Switch #7 to the OFF position, regardless of your other DIP Switch settings. The 15 amp and 30 amp Prostar Gen3 models are the newest and smallest Morningstar controllers to include the seven preset and custom charging configurations, and the option to disable auto-equalization. Other larger Morningstar controllers which include similar preset configuration options are the Prostar MPPT, TriStar, and TriStar MPPT controllers.
