Schedule Maintenance Items
Monthly, or After Each
Equalization
Inspect the battery bank.
Look for cracked or
bulging cases, and corroded
terminals.
For wet cell (flooded type)
batteries, make sure the
water level is correct. Wet
cell water levels should be
checked monthly or accord
-
ing to the manufacturer’s
recommendations.
Annually
Clean the heatsink fins with a
clean, dry rag.
Inspect all wiring for
damage or fraying.
Inspect for nesting insects.
Re-tighten all wiring
terminal connections to
specified torque values.
Inspect the system earth
grounding for all compo

5.1 Alarms
High Temperature Current Limit
The ProStar will limit the solar input current if the
heatsink temperature exceeds safe limits. Solar
charge current will be de-rated (to 0 Amps if needed)
to reduce the heatsink temperature. The ProStar
is designed to operate at full rated current at the
maximum rated 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 relocate the controller to a cooler spot.
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 or Shorted
The heatsink temperature sensor is damaged. Return
the controller to an authorized Morningstar dealer for
service.
Battery Sense Out of Range, or 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.
