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 Invert 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 0.5 V below
the set upper threshold of Batt Over Volt.
(b) AC input is available and PRO-Verter is operating in Charge mode:
•
There will be no AC output or charging.
•
The fault will be cleared automatically when the battery voltage drops to 0.5 V below
the set upper threshold of Batt Over Volt. The PRO-Verter will restart in Invert 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 Charge
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 1 A 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 and charging
will be stopped. The blue Status LED will be switched off and the red Fault LED will be
steady on. The alarm in PRO-Verter will beep steady.
•
The 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 Status LED will be switched off and the red Fault LED will be steady on. The alarm
will beep steady.
•
The PRO-Verter will be off and will require manual reset by powering off, waiting for 1
minute, and then powering on again.
•
Ensure 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.
