5.0 Operation
Dead Battery charge
– This fault has detected a very discharged
battery bank or a battery bank that is disconnected from the inverter. The
unit is attempting to enter the charge mode, but has detected less than 7
volts (12-volt models), 14 volts (for 24-volt models) or 28 volts (for 48-volt
models) on the battery bank. This fault will continue until current is able to
fl
ow into the battery from the battery charger. Once this happens, the fault
will automatically reset.
Remedy:
Check the DC voltage on the inverter’s DC terminals and
compare it with the DC voltage on the battery bank, these two volt-
ages should be very close (<0.5 VDC difference). If not, check to
ensure all connections are tight and the fuse/circuit breaker between
the inverter and battery bank is good.
Overcurrent
- This fault causes the inverter to shut down to protect
internal power components and may be caused by an excessive AC load. If
the overload condition lasts for less than 10 seconds, the unit will automatically
restart and resume operation. However, if the overcurrent condition occurs, more
than 10 seconds, the unit will shut down and will require a manual restart.
Remedy:
This fault usually occurs because the connected AC loads
are larger than the inverter’s output capacity, there is a wiring short
on the AC output, or the wires are incorrectly wired. Once the AC
loads are reduced or the output wiring is corrected; manually restart
the inverter to resume operation. If this fault condition continues
after all of these recommendations, perform a inverter reset (see
section 6.2).
