Xantrex RV Series Inverter/Charger Owner’s Manual
24
Lobat/Start Chrg:
The batteries have reached their minimum allowable charge and the charger
will now take over and begin recharging them if AC power is present to the inverter. If no AC
power is present then the automatic Low Battery Cut-Off (auto LBCO) will take over to protect the
batteries from over discharge and to protect the AC loads from unregulated power (brown-out
conditions).
Otemp/Less Load:
The inverter’s internal temperatures are too high and the loads need to be
reduced. The inverter will automatically reset after the internal temperature has dropped to a safe
level. If the loads are still too great the inverter may heat up and fault again. This will go on
indefinitely until the problem is remedied. This may be caused by installation in a poorly ventilated
area, but usually it is the result of trying to power too many loads at one time.
Oload/Less Load:
The loads that are being driven by the inverter are more than it can handle.
The loads must be reduced and then the inverter will automatically attempt a reset.
Bat State of Chg:
This menu shows the state of charge of the storage batteries as either a
percentage of full or in an “E------F” gas gauge format.
Time Left To Run:
Displays the calculated approximate time in hours and tenths of hours that are
left in the storage batteries. This time is based on the usage of the system during the past “
X
”
minutes, and is updated constantly.
Time Left To Charge:
Displays the calculated approximate time in hours and tenths of hours that
are remaining in the charging process.
Meters Menu
Six meters are available on the RC7. These meters may be accessed from any point in the
display by pressing and holding the right
Menu Item
button for five seconds. The
Menu Item
buttons are then used to scroll through the different meters.

Setup Menu
The Setup menu allows the different settings in the inverter to be altered. The RC7 is the only way
that the inverter’s set points may be changed. The Setup menu is accessed by pressing and
holding both
Menu Item
buttons for five seconds. Once in the Setup menu use the
Menu Item
buttons to move about vertically and use the
Settings
button to move left in the menu tree. The
Setup menu has the following categories:
Search Sense:
The search sense is the sensitivity or the minimum load needed to “wake up” the
inverter. See “Search Sense Mode Using Optional RC7 Remote” on page 5. This setting is given
in increments starting at
Defeat
up to the
>40 W
setting. Defeat will disable the search sense
mode and the inverter will always sit at full voltage ready to power a load.
Auto LBCO:
Or automatic low battery cut-off mode. This mode is set either on or off. In the
on
position the inverter will automatically disconnect from the battery if battery voltage drops below a
set point of 10.5 volts. The inverter status LED and
user menu
display will show the error
condition. This protects the batteries from over-discharge and the AC loads from unregulated
power (brown out). In order to restart the system the batteries will need recharging from an
outside source. The Auto LBCO defeat (off position) is meant only as a means of emergency
