Fault Message
Symptoms and Troubleshooting
Battery over voltage!
The PRO-Verter is in FAULT MODE because the battery voltage has risen to the
programmed upper threshold of “BATT OVER VOLTAGE”.
(a) AC input is not available and PRO-Verter is operating in Inverting Mode:
• There will be no AC output because the Inverter will be switched OFF. The Blue “Status”
LED will be switched OFF and the Red “Fault LED” will be steady ON. The alarm 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 PRO-Verter is operating in Charging Mode:
• There will be no AC output or charging.
• 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 PRO-Verter 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 PRO-Verter will, thus, resume operation in
“Charging Mode”,
Input over current!
The PRO-Verter 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” / “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 alarm in PRO-Verter will beep steady.
• PRO-Verter will be turned off and will require manual reset by turning OFF the main
breaker, waiting for 1 minute and then turning ON the main breaker.
• The set threshold of “ GRID MAX CURRENT” / “GEN MAX CURRENT” 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”
accordingly.
Output over current!
The PRO-Verter is in FAULT MODE because the instantaneous output current being drawn
from the PRO-Verter inverter by the AC load is 330% of the rated value of the PRO-Verter
for 2 samples (current is sampled every 33.3 μs).
• There will be no AC output because the PRO-Verter inverter will be switched OFF. The
Blue LED marked “Status” will be switched OFF and the Red LED marked “Fault” will
be steady ON. The alarm will beep steady.
• PRO-Verter will be OFF 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% (30 A) of the rated current (10 A) of the inverter for more than 1 millisecond.
