High Temperature Current Limit
The EcoBoost MPPT 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 EcoBoost MPPT is designed
to operate at full rated current at the maximum ambient
temperature. This alarm indicates that there is insufficient
airflow and that the heatsink temperature is approaching
unsafe limits. If the controller frequently reports this alarm
condition, corrective action must be taken to provide better
air flow or to re-locate the controller to a cooler spot.
High Input Voltage Current Limit
The EcoBoost MPPT will limit the solar input current as
the solar array Voc approaches the maximum input voltge
rating. The array Voc should never exceed the 120 volt
maximum input voltage - see the array voltage de-rating
graph in Appendix.
Current Limit
The array power exceeds the rating of the controller. This
alarm indicates that the EcoBoost MPPT 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 recommended 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.
Uncalibrated
The controller was not factory calibrated. Return the
controller to an authorized Morningstar dealer for service.

Adjusting Set-points with the Meter Display
The EcoBoost MPPT is available in metered and
non-metered versions. The metered model allows:
• Custom programming directly from the unit.
• Extensive settings adjustment and information as shown
partially in Figure 4-2 below.
