When you need a mid-range solar charge controller with maximum power point tracking (MPPT) technology, the Morningstar ProStar MPPT series is perfect. The ProStar MPPT series balances features and price so that you get a high performance controller without spending too much money. Morningstar has incorporated the most important features that are often found on higher end models, while keeping the unit very simple and easy to use. Their patented TrakStar technology will maximize your solar yield so that your off-grid system can deliver all available energy to your batteries. The MPPT series of controllers will always outperform the standard pulse width modulation (PWM) type of controllers. Whether your solar panels must deliver the most power possible to your batteries or you just want to ensure that your system is operating at its highest efficiency, the ProStar MPPT series is a great choice.

NOTE: The PS-MPPT controller is only UL 1741 compliant when installed with the optional PS-MPPT-WB wire box.
