Symptom Possible Cause Possible Remedy
AFCI indicator and
combiner AFCI
Annunciator
lit.
Arc fault event.
NOTE : The SOLAR ON indicator remains lit.
If an arc fault is present, the shutdown of the system
constitutes correct operation. The ICS Plus does not
need troubleshooting. Investigate any potential
causes throughout the PV system.
Arc fault self-test button was pressed. Turn combiner disconnect switch or Rapid
Disconnect switch off, then on. Reset all RTB devices.
AFCI
indicator lit.
Combiner
AFCI
Annunciator
not lit.
Arc fault in another combiner (multiple
combiner system only).
NOTE : The SOLAR ON indicator remains lit.
Check all combiners. An arc fault will activate the
AFCI Annunciator in that combiner only.
SOLAR OFF
indicator lit.
RTB cannot be
turned on.
Rapid Shutdown switch is in off position.
System is in “safe” condition with PV
contactors disconnected and RTB forced to
the off position. Turn Rapid Shutdown switch on. Once it is on, turn
on the RTB.
SOLAR OFF
indicator and
another indicator
both lit.
RSI miswired. Check all wiring between RSI and combiner.
SOLAR ON
indicator lit, but
charge controller
does not register
PV input.
Combiner disconnect switch turned off. Turn on combiner disconnect switch.
SOLAR ON
indicator lit, but
charge controller
registers reduced
PV input.
Array wiring error or poor connection. Check all PV wiring to combiner. Use DVM to
confirm voltage of each subarray at combiner
input terminals.
Fuses blown in combiner box. Check all fuses.
No indicators lit.
RTB off. Turning
RTB on does not
enable PV. Battery or DC source is disconnected. Loss of
combiner box control voltage caused the PV
contactor to disconnect. System is not in the
formal “safe” condition, although PV array is
still forced to be off. Check all DC disconnect devices. Check
BKR-CTRL-DC fuse. Use DVM to confirm voltage at
BKR-CTRL-DC terminals.
NOTE : Once voltage is established, RTB must be
manually turned on (if not already on).
SOLAR OFF
indicator does not
light when Rapid
Shutdown switch
is turned off.
Battery or DC source is disconnected.
System is not in the formal “safe” condition,
although PV array is still forced to be off. Check all DC disconnect devices. Check the
BKR-CTRL-DC fuse. Use DVM to confirm voltage at
BKR-CTRL-DC terminals.
NOTE : Once voltage is established and RTB is off,
SOLAR OFF indicator should light. See below.
SOLAR OFF
indicator does not
light when Rapid
Shutdown switch
is turned off after
DC reconnection.
RTB is turned on. System is not in “safe”
condition. Rapid Shutdown switch was not
able to turn the RTB off due to DC loss.
NOTE
: This may not be a valid test. Wait at
least one minute after DC reconnection.
Turn RTB off if necessary, or wait. Within 30 seconds,
the RSI will turn the RTB to the off position
automatically to force a “safe” condition. The
SOLAR OFF indicator should light.
