Battery over voltage!
EVOTM Inverter/Charger is in FAULT MODE because the battery voltage has risen to the set
upper threshold of “BATT OVER VOLTAGE”
(a) AC input is not available and EVOTM Inverter/Charger is operating 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 EVOTM Inverter/Charger will beep steady
• The fault will be cleared automatically when the battery voltage drops to 0.5V below
the set upper threshold of “BATT OVER VOLT”
(b) AC input is available and EVOTM Inverter/Charger is operating in Charging Mode:
• There will be no AC output or charging because the Transfer Relay will be de-energized
and PWM drive to the Inverter Section will be switched OFF.
• The fault will be cleared automatically when the battery voltage drops to 0.5V below to the
set upper threshold of “BATT OVER VOLT”. The EVOTM Inverter/Charger will restart in Inverting
Mode, synchronize with the AC input and then, the Transfer Relay will be energized to transfer
to AC input at zero crossing. The unit will, thus, resume operation in “Charging Mode”
Input over current!
EVO
TM
Inverter/Charger is in FAULT MODE because the input current being drawn from the
AC input source (Input current = Charging Current + Pass Through Current to the load) is 1A
more than the set threshold of “ GRID MAX CURRENT” / "GEN MAX CURRENT"
for 5 seconds (current is sampled every 33.3 µs).
• There will be no AC output because the Transfer Relay will be de-energized, charging will
be stopped and PWM drive to 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 EVOTM Inverter/Charger will beep steady
• EVOTM 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
• The set threshold of “ GRID MAX CURRENT” / "GEN MAX CURRENT" (Section 4.5.2.2)
should match the breaker capacity of the AC input source / AC input Branch Circuit. If
AC input current capacity cannot be increased, reduce the AC load / “BULK CURRENT”
(Section 4.4.2.1) accordingly.
Output over current!
EVO
TM
Inverter/Charger is in FAULT MODE because the instantaneous output current
being drawn by the AC load in Inverting Mode is 330% of the rated value of the EVO
TM
Inverter/Charger for 2 samples (current is sampled every 33.3 µs).
• 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
TM
Inverter/Charger will beep steady
• EVO
TM
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 the maximum instantaneous surge current of the load is not more than
300% of the rated current of the EVO
TM
Inverter/Charger for 1 millisecond
EVO
TM
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 EVOTM Inverter/Charger will beep steady
• EVOTM 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 specied limit

• 140% for 30 sec for EVO-2212 / 3012 / 2224 / 4024
Output over load 4!
Output power is over the Power Boost Rating:
• 150% for 30 sec for EVO-1212F / 1212F / 1224F / 1224F-HW
• 150% for 5 sec for EVO-2212 / 3012 / 2224 / 4024
