Morningstar PS Series Controllers – This was one of Morningstar’s first products and it is an industry favorite. Available in 15 amp or 30 amp, it has all of the features of a traditional (non-MPPT) charge controller, including charge and load management, optional integrated display, and basic data loggging. The PS series has settings for gel, AGM or flooded batteries. Built in on/off switch and temperature compensation. Available with or without a built-in meter.
