Fault Messages and Troubleshooting Guide
EVO™ Inverter/Charger is in FAULT MODE because of overload conditions in Inverting Mode:
•
There will be no AC output because the Inverter Section will be switched OFF. The Blue LED
marked "Status" will be switched OFF and the Red LED marked "Fault" will be steady ON. The
buzzer in EVO™ Inverter/Charger will beep steady
•
EVO™ Inverter/Charger will be latched in OFF condition and will require manual reset
by powering OFF, waiting for 1 minute and then powering ON again
•
Ensure that overloading is limited to the specified limit
•
<96 Vrms for 300 cycles for (i) EVO-1212F / 1212F / 1224F / 1224F-HW and (ii) EVO-2212 / 3012
/ 2224 / 4024
•
<184 Vrms for 300 cycles for EVO-2212E / 3012E / 2224E / 4024E
•
<96 Vrms (Phase Voltage) for 300 cycles for EVO-4248SP
Output power is over the Power Boost Rating (110%) for 30 min
Output power is over the Power Boost Rating
•
120% for 10 min for (i) EVO-1212F / 1212F / 1224F / 1224F-HW and (ii) EVO-4248SP
•
120% for 5 min for EVO-2212 /2212E / 3012 / 3012E / 2224 /2224E / 4024 / 4024E
Output power is over the Power Boost Rating (140%) for 30 seconds
•
140% for 1 min for (i) EVO-1212F / 1212F / 1224F / 1224F-HW and (ii) EVO-4248SP
•
140% for 30 sec for EVO-2212 /2212E / 3012 / 3012E / 2224 /2224E / 4024 / 4024E
Output power is over the Power Boost Rating (150%) for 5 seconds
•
150% for 30 sec for (i) EVO-1212F / 1212F / 1224F / 1224F-HW and (ii) EVO-4248SP
•
150% for 5 sec for EVO-2212 /2212E / 3012 / 3012E / 2224 /2224E / 4024 / 4024E
EVO™ Inverter/Charger is in FAULT MODE because there is a short circuit on the output side in Inverter
Mode. Short circuit protection is activated as follows:
(i) EVO-1212F/1212F-HW/1224F/1224F-HW: The output current has exceeded the value of the rated
output current leading to the output voltage dropping to <15 Vrms for 6 cycles
(ii) EVO-2212/3012/2224/4024 and EVO-2212E/3012E/2224E/4024E: The output current has exceeded
the rated output current leading to the output voltage dropping to <15 Vrms for 6 cycles
(iii) EVO-4248SP: The output current (Phase Current) has exceeded the rated current leading to the
Phase Voltage dropping to <15 Vrms for 6 cycle
•
There is no AC output because the Inverter Section has been switched OFF. The Blue LED marked
"Status" will be switched OFF and the Red LED marked "Fault" will be steady ON. The buzzer in
EVO™ Inverter/Charger will beep steady
•
EVO™ Inverter/Charger will be latched in OFF condition and will require manual reset
by powering OFF, waiting for 1 minute and then powering ON again
NOTE: If there is short circuit condition in Charging Mode i.e. when AC input is available, short circuit
condition on the output side will trip the AC input breaker. The load will be transferred to the Inverter
Section and the Inverter Section will then see short circuit condition and will shut down as described
above
EVO™ Inverter/Charger is in FAULT MODE because AC input from Grid / Generator has been connected
to the AC Output terminals by mistake. 10VAC or above seen at the AC Output Terminals at the time
of boot up of EVO™ Inverter/Charger will activate this protection
•
The Blue LED marked "Status" will be switched OFF and the Red LED marked "Fault" will be
steady ON. The buzzer in EVO™ Inverter/Charger will beep steady
•
EVO™ Inverter/Charger will be latched in OFF condition and will require manual reset
by powering OFF, waiting for 1 minute and then powering ON again
Check the connection. If there is 10V over at the output terminal, remove the connection.
