Please click here to download the Sizing Benefits of MPPT Controllers with Nominal Voltage Arrays white paper. The tracking capabilities of many MPPT controllers require a voltage input window that must be significantly higher than battery voltage.  Morningstar’s MPPT controllers, on the other hand, are engineered to impose no such limitation, and in many cases, we encourage these configurations for the optimal performance and cost benefits.
