appears on the LCD and the FAULT
(red) LED is on. The PWR (green), CHG (green), and
INV (green) LEDs are off.
• High Volts AC (High VAC)
– This fault causes the AC input to be disabled due to a very high
AC voltage (>145 VAC; or >290 volts for export inverters) has been detected on the AC input.
Remedy:
Remove all AC power from the inverter’s AC input for 15 minutes to reset this
fault. Ensure only 120VAC power is connected to each of the inverter’s AC inputs.
Low Battery
appears on the LCD and the FAULT
(red) LED is on. The PWR (green), CHG (green) and
INV (green) LEDs are off.
• Low Battery (Low Batt)
– This fault displays when the battery voltage drops below the
SETUP menu’s
02B LBCO Volts
setting for more than one minute, and only occurs if the inverter
was “Inverting” or “Searching”.
Remedy:
This fault automatically restarts and resumes operation when the battery
voltage rises to
≥
12.5 VDC (12V models),
≥
25 VDC (24V models), or
≥
50.0 VDC (48V
models); or, if AC power—such as utility power or a generator—is connected to the
inverter/charger’s input and battery charging begins.

appears on the LCD and the

• No Inverter Found! (Empty)
– This fault indicates communication data from the inverter’s
Remote (blue) or Network (green) connection to the router’s remote port (P1-P6) is missing.
Remedy:
Check for the following conditions that can cause a “No Inverter Found!” fault.
a) The router’s remote port (P1-P6) that is connected to the inverter may be bad, try a
different remote port on the router to see if communication is restored.
b) The remote cable from the inverter to the router’s remote port is either the incorrect
cable, connected incorrectly, or has gone bad. See Section 2.4 for cable information.
c) If a Tfmr Overtemp fault occurs for more than 10 seconds, the inverter automatically
resets. After the inverter resets, the display changes from “
Tfmr Overtemp
” to “
No
Inverter Found!
”. View the
TECH: 05 Fault History
menu to determine if a Tfmr Overtemp
fault occurred; if this is the case, the inverter requires service/repair.
d) The communications IC in the router may be bad, try another router display.
e) Reconnect the router from the inverter’s Remote (blue) port to the Network (green)
port. If this does not
fi
x it, then the inverter may need servicing.
