15.2 WARNING DEFINITIONS AND TROUBLESHOOTING
CODE DESCRIPTION TROUBLESHOOTING
W000 Communication failure with battery
Check the inverter battery settings to ensure they
are set for the specific battery type. Check the
battery communications cable for proper
pinning/installation.
W001 AFCI Com failure
Restart the inverter. If the error persists, contact the
distributor.
W002 AFCI High
Check each PV string for correct open circuit
voltage and short circuit current. If the PV strings
are in good condition, clear the fault on inverter
LCD.
W003 Meter communication failure
Check communications cable. If the error persists,
contact the distributor.
W004 Battery BMS fault
Inverter is receiving a fault from the battery’s BMS.
Restart the battery and ensure the communication
cables are installed correctly. If the error persists,
contact the distributor.
W006
RSD Active
Check if the RSD switch is pressed.
W007 LCD communication fault
Restart the inverter. If the error persists, contact the
distributor.
W008
Firmware mismatch
Contact the distributor for a firmware update.
W009
Fan Stuck
Verify the fans are operable.
