Configurations
Switch Options
The inverter can be configured by the factory or through the NVM Setup Utility to have different local and remote
switch configurations. The local switch may be set to enabled or disabled. The remote switch may be set to snap or
momentary.
If the local switch is set to enabled, the remote switch must be set to momentary. There is one switch combination
that is not allowed. If the remote is set to snap, the inverter may not respond correctly to changes in the remote
switch’s state. Refer to Table 6. This is also true if the inverter remote switch is set to momentary, but a snap style
switch is used.

Low Battery Shutdown
Low Battery Shutdown is a protective measure to prevent deep discharge of the battery and/or to make sure that
the starting batteries have enough power to start the vehicle.
NOTE: If the inverter is shutdown in low battery conditions, the unit will go into a hard shutdown for under
voltage protection (UVP) if the battery is not charged up to the inverter’s auto recovery voltage of 13.5 V after
15 minutes. The inverter will be completely off and there will be zero current drawn in UVP. Cycling the “On/
Off ” switch (remote switch only for “R” suffix) will immediately restart the inverter if the voltage is above the low
battery threshold at the DC input terminals.
NOTE: The inverter may be de-rated when the input voltage approaches the low battery set-point. To conserve
battery voltage, the internal inverter fan may turn off. This will cause the inverter to go into high temp shutdown if
the load is large enough.
Sleep Mode (Load Sense)
The inverter has a sleep mode feature which if enabled can significantly reduce DC power drawn over long periods
of no-load operation to help preserve battery life. If sleep mode is enabled, the inverter output will automatically
turn off when AC loads greater than 20 W are not present for 60 seconds. The inverter will check for the presence
of a load once a second and will automatically restart once a load is detected.
NOTE: While in sleep mode, it may take up to one second for the load to receive power once it has been applied.
NOTE: The LED on the GFCI will blink when the inverter has gone to sleep.
