Chapter 7 Trouble Shooting
The SunStar performs a continuous self-test to monitor controller and system operation.
Detected problems are classified as either faults or alarms. Typically, faults are problems
that stop the normal operation of the controller and require immediate attention. Alarms
indicate an abnormal condition, but will not stop the controller’s operation.
General Troubleshooting
SunStar is not powering up
z
Confirm that all circuit breakers and switches in the system are closed
z
Check all fuses
z
Check for loose wiring connections and wiring continuity
z
Verify that the battery voltage is not below 9Vdc
z
Verify that the battery power connection is not reversed polarity
The BTS is not working properly
z
Check for a reverse polarity connection on the sense leads
z
Verify that the BTS connections are wired to the correct terminals
z
Check for shorts and continuity in the cables
z
Verify that good electrical contact is made at the terminals
z
Note that if the SunStar is restarted with a BTS fault present, it will not detect the BTS
and the LED indication will stop
Troubleshooting Solar Charging
z
Over-charging or under-charging the battery
z
DIP switch settings may be wrong
z
BTS is not correcting for high or low temperatures
z
Over-temperature condition is reducing the charging current (heat sink cooling may be
blocked — indicated with LED’s)
z
Voltage drop between SunStar and battery is too high
z
Battery charging requires temperature compensation (connect a Battery Temperature
Sensor (BTS)).
z
Load is too large and is discharging the battery
Not charging the battery
z
DIP switch settings may be wrong (check each switch position carefully)
z
SunStar has detected a fault
z
Solar circuit breaker or disconnect is open
z
Reversed polarity connections at the solar terminals (SunStar will not detect the solar
array)
z
Short circuit in the solar array has eliminated part of the array output
z
Solar array is not providing enough current (low sun or fault in the array)
z
Battery is failing and cannot hold a charge
