Exact Solar used Morningstar’s charge controller for a DC transfer grid-tied battery backup application in Pennsylvania. The installer chose Morningstar for its low cost, easy installation and compatibility with the small battery and inverter/charger. The TriStar MPPT 600V with DC transfer switch was also a good option in light of concerns with low-voltage shutdown issues associated with AC coupling.
