Figure 5-17, Dead Battery Charge Fault

• 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 9
volts (12-volt models), 18 volts (for 24-volt models) or 36 volts (for 48-volt
models) on the battery bank. This fault will continue until current is able to
flow into the battery from the battery charger. Once this happens, the fault
will automatically restart.
Remedy: Check the DC voltage on the inverter's DC terminals and
ensure it is the same as the battery bank, these two voltages should
be very close (<0.5 VDC difference). If not, check to ensure all con-
nections are tight and the fuse/circuit breaker between the inverter
and battery bank is good.
This fault clears when the AC input is removed or when greater than
9 volts (12-volt models), 18 volts (for 24-volt models) or 36 volts
(for 48-volt models) is detected by the inverter when charging.

Figure 5-18, Overcurrent Fault

• Overcurrent - This fault causes the inverter to shutdown 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
these recommendation, perform a inverter reset (see section 6.2).
