MorningStar ProStar PS-15 New Gen 3 Charge Controllers

Morningstar’s PS-15 has been upgraded. This new third generation model offers additional features and capabilities while maintaining the same form factor, quality, and reliability that has made the ProStar the world’s leading mid-range PWM solar controller for professional and consumer applications since 1995.

The PS-15 solar charge controller has been the leading mid-range pulse width modulation (PWM) controller since 1995. These charge controllers are highly durable with high strength polycarbonate cases, protective terminal covers, and extruded aluminum heatsinks. Open standard MODBUS communications protocol allows for control and remote data access. The MOR PS-30 Gen 3 ProStar Charge controller is both efficient and lasting with low voltage drops and an estimated 15-year lifespan.
