State and Event Codes
Appendix F
PWRcell™ Inverter State and Event Codes
Valid for HW Versions 1002, 1010 FW Version 13590
Inverter States
Display texts for states will be steady and viewable on the inverter device page at the inverter control panel, unless
listed below as transient.
Refer to diagnostic procedures in the right most column as necessary. Refer to the inverter section of the PWRcell
Diagnostic Repair Manual for detailed descriptions of diagnostic procedures. If unable to resolve functionality, please
call PWRcell Technical Support at 1 (855) 635-5186.
Faults: Low = low impact to performance, device will recover; Med = noticeable impact to performance but still
recoverable; High = high impact to performance or could render device inoperable - device will try to recover.
Errors: Requires manual intervention before device can operate.

Transient/ Severity Description
Steady
Steady Normal Inverter is disabled
Steady Normal The ESTOP is active and
inhibiting the inverter
Transient Normal Inverter is initializing after enable
command
Transient Normal Inverter is waiting on supply
voltage
Transient Normal Inverter is waiting on internal and
external DC voltages to equalize
before closing REbus relays
Transient Fault Inverter is determining if/ where a
(Med) DC bus fault occurred
Steady Fault REbus voltage too low for
(Low) operation. AC power may be
disconnected or mis- wired.
Continued From Above
Transient Normal Non-switching state Inverter is
connected to the bus and ready to
move power
Transient Normal Inverter is waiting for internal
timer to expire, or an external
condition (voltage, frequency,
temp) to come into specification
Steady Fault Inverter is waiting to detect the
(High) REbus heartbeat
Transient Normal Inverter is connecting to the grid
