Passive Cooling And The Sound Of Silence

March 25, 2015

Since Morningstar controllers are passively cooled without any internal fans or moving parts, they are very reliable. Fans and other parts are subject to failure and replacement can be very problematic, especially for controllers installed in difficult to access, remote areas. But in addition to issues related to mechanical performance, and debris drawn into the controller by these fans, the noise they create can be irritating in residential applications. With passive cooling, you not only minimize the chance of defects, but you also benefit from the sound of silence.

Diagnosing Alarms With The Meter Map

February 27, 2015

If your Morningstar controller’s meter is displaying an alarm, it is helpful to consult the meter map for the particular controller you are using in order to access additional helpful information.  The arrows on the map correspond to the arrow buttons on your meter, and the sequence that they need to be pressed in order to display the diagnosis.  If you did not save the meter map that came with your controller, you can access it on the Morningstar Support site.

Temperature Sensing

January 31, 2015

During one of our webinars, a question came up about battery temperature sensing associated with Morningstar charge controllers.  Just to clarify, our TriStar MPPT family of controllers come with a remote temperature sensor (RTS) included.  The TriStar PWM does not come with a remote temperature sensor but an RTS can be purchased separately. All other MS controllers include an internal temperature sensor.  In addition to the TriStar PWM mentioned above, if more accurate battery temperature sensing is desired, the RTS accessory can be purchased for the SunSaver MPPT, SunKeeper, SunSaver DUO, and ProStar.
