The Prostar PS-15M-48V provides several unique features and protections:
- Provides for longer battery life and improved system performance.
- It comes with a highly accurate digital meter.
- Morningstar’s patented PWM battery charging has been further optimized.
- The Digital Display meter reads values directly from the micro-controller, which ensures a very accurate voltage and current measurement.
Morningstar’s Optional Remote Temperature Sensor (RTS) provides accurate battery charging in solar systems that experience temperature variations during the year. When used with the ProStar controller, this temperature sensor improves on-board temperature compensation by measuring the temperature at the battery. Use with the ProStar whenever the temperature at the battery will be more than 9 degrees Fahrenheit different than the temperature at the controller.
