“W” models
Range: 00 to 510 VAC
Reads the RMS value of the AC voltage at the inverter’s AC HOT 1 input and NEUTRAL IN 1 terminals.
This is usually the connection for the utility grid. Value will drift around before inverter has synchronized.

Reads the RMS value of the AC voltage at the inverter’s AC HOT 2 input and NEUTRAL IN 2 terminals.
This is usually the connection for a back-up, fuel-powered generator. Value will drift around before inverter
has synchronized.

60 Hz models
Range: 53 to 67 Hz
50 Hz models
Range: 44 to 56 Hz
Reads the frequency of the AC source that the inverter is synchronized to. This value may drift around
until the inverter has synchronized to the source. Once synchronized, the inverter follows the frequency of
the AC source it is connected to.
INFORMATION DISPLAY
The following information is displayed as additional Menu Items.
AC1 & AC2 volts valid only when inverter synced to that input.
Batt volt actual is used for LBCO, HBCO, LBX, LBCI, sell volts and gen starting.
Batt volt temp comp is used for float, bulk, eq & aux relays
ERROR CAUSES (5) MENU HEADING
When an error has occurred, the red ERROR LED on the control panel will be illuminated. If a generator
error has occurred, the ERROR LED will blink slowly. This menu is provided to assist with the investigation
into the error cause. If an error condition has occurred, the word NO will be changed to YES. To reset the
error, turn the inverter OFF and then ON.
Over Current
NO
Too large of a load was connected or the AC output wiring was short-circuited. This can occur in inverter
or charger mode. To clear this fault, disconnect the loads and restart the inverter. To restart, push the red
ON/OFF MENU button on the control panel and then select OFF and then ON or SRCH. Reconnect the
loads one at a time to find the load or combination of loads that cause the problem. If the inverter will not
restart with all loads and inputs disconnected remove all AC wiring from the terminal block and try to
restart again. If it restarts, the problem is with the wiring. If it does not restart, refer to the
TROUBLESHOOTING GUIDE on page 112.
Transformer
overtemp
NO
Heatsink
overtemp
NO
The transformer or power transistors have exceeded their safe operating temperature and the inverter has
turned off. When operating as a battery charger, the inverter will reduce its charging rate to prevent
overheating. As an inverter, overheating can be caused by attempting to operate too large of a load for too
long, a failure of the inverter cooling fans, or that the air flow into or out of the inverter is being blocked.
The inverter will automatically reset once it has cooled. While the inverter has shut down, AC power from
any AC source will not pass through the inverter to power AC loads. Any power management provided by
the inverter will not be able to occur while the inverter is off.
