PS-MPPT-40 Morningstar MPPT Solar Charge Controller 12/24V 40A ProStar

Morningstar ProStar PS-MPPT-40 MPPT Solar Charge Controller 12/24V 40A

The Morningstar ProStar PS-MPPT-40 is a high-efficiency MPPT solar charge controller delivering 40A of charge current for 12V and 24V battery systems. Using advanced Maximum Power Point Tracking technology, it extracts up to 30% more energy from solar panels compared to PWM controllers — making it ideal for off-grid systems where maximizing solar harvest is critical. MeterBus communication enables remote monitoring and configuration via optional accessories and MSView software.
