EVO™ Inverter/Charger is in
FAULT MODE
because the battery voltage has risen to the set upper
threshold of “BATT OVER VOLTAGE”
(Section 4.4.2.6)
(a) AC input is not available and EVO™ Inverter/Charger is operating in Inverting Mode:
•
There will be no AC output because the Inverter Section will be switched OFF. The Green 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
•
The fault will be cleared automatically when the battery voltage drops to 0.5V below the set
upper threshold of “BATT OVER VOLT”
(Section 4.4.2.6)
(b) AC input is available and EVO™ 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”
(Section 4.4.2.6)
. The EVO™ 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”

INFO
This FAULT MODE will be activated only when parameter "INPUT OC PROTECT" has been set
to option "1=shutdown"
(See Section 4.5.2.10 for additional details)
.
EVO™ Inverter/Charger is in
FAULT MODE
because the input current being drawn from the AC input
source (Input current = Charging C Pass Through Current to the load) is 1A more than the
set threshold of “ GRID MAX CURRENT”
(Section 4.5.2.2)
/ "GEN MAX CURRENT"
(Section 4.5.2.3)
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 Green 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
•
The set threshold of “ GRID MAX CURRENT”
(Section 4.5.2.2)
/ "GEN MAX CURRENT"
(Section
4.5.2.3)
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.

o v e r c u r r e n t
!
EVO™ 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™ 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 Green 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 the maximum instantaneous surge current of the load is not more than 300% of the
rated current of the EVO™ Inverter/Charger for 1 millisecond
