Switch Options

The inverter can be configured by the factory or through the CAN configuration
interface 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.
"Snap" and "momentary" describe the type of switch that is used.
There is one switch combination that isn't allowed. If the local switch is set to enabled,
the remote switch must be set to momentary. If the remote is set to snap, the inverter
may not respond correctly to changes in the remote switch's state. 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 13.5V 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 high enough.

Shutdown Timer

As an alternative to sleep mode, a factory configured shutdown timer is available to
disable the inverter after fixed periods (regardless of output load). Standard timer
settings are OFF, 30 minutes and 60 minutes. Following shutdown, the DC input
current will be less than 0.5mA. Cycling the ON/OFF control will restart the inverter.

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 20W are not present for 60 seconds. The inverter will check for the
presence of a load once a second and will automatically restart on when it reappears.
