Alarms
High Temperature Current Limit
The TriStar MPPT 150V will limit the solar input current if the heatsink temperature exceeds safe
limits. Solar charge current will be tapered back (to 0 amps if needed) to reduce the heatsink
temperature. The TriStar MPPT 150V is designed to operate at full rated current at the maximum

spot.
High Input Voltage Current Limit
The TriStar MPPT 150V will limit the solar input current as the solar array Voc approaches the
maximum input voltage rating. The array Voc should never exceed the 150 Volt maximum input
voltage. See the array voltage derating graph in Section 8.0.
Current Limit
The array power exceeds the rating of the controller. This alarm indicates that the
TriStar MPPT 150V is limiting battery current to the maximum current rating.
RTS Open
The Remote Temperature Sensor is not connected to the controller. Use of the RTS is recom-
mended for proper battery charging.
Heatsink Temperature Sensor Open / Shorted
The heatsink temperature sensor is damaged. Return the controller to an authorized Morningstar
dealer for service.
Battery Sense Out of Range / Disconnected
A battery sense wire is disconnected. Inspect the battery sense connections. This alarm is set
when the voltage at the battery sense voltage differs by more than 5 volts from the voltage at the
battery terminals.
Uncalibrated
The controller was not factory calibrated. Return the controller to an authorized Morningstar
dealer for service.
