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.
