5.0 Operation
FAULT !
High VAC
• High Volts AC Fault – Charger is disabled due to a very high AC voltage
(>150 VAC, >260 VAC – export models) detected on the AC input.
Remedy: Remove all AC power from the inverter's AC input for at
least 15 minutes to automatically restart this fault. Ensure only 120
VAC power is connected to each of the inverter's AC inputs. Check
and correct the high voltage problem from the source.
FAULT !
Low Batt
• Low Battery Fault – The inverter turns off to prevent the batteries from
being over-discharged. The FAULT LED illuminates when the battery voltage
drops below the LBCO setting for >1 minute. The inverter automatically
restarts and resumes operation when the battery voltage rises to ≥12.5 VDC
(12v models), ≥25.0 VDC (24v models), or ≥50.0 VDC (48v models).
Remedy: This fault will also automatically restart if AC power (such
as utility/shorepower or a generator) is connected to the inverter/
charger's input and battery charging begins.
FAULT !
No Comm
• No Comm – Remote is not receiving any information from the inverter.
Remedy: Reset the remote by disconnecting the remote commu-
nications cable from the inverter for 5 seconds, and then reconnect
it (see Figure 2-3). If the fault continues, fi rst check/replace the
remote cable. This cable is 4-wire telephone cable.
