Xantrex RV Series Inverter/Charger Owner’s Manual

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. Solar Panel DC Amps, Battery Voltage DC, DC current, AC Input Volts AC and Volts Peak, AC Output, and Pass-thru Amps are all available to accurately monitor both AC and DC sides of the system.

To exit the Meters menu, press and hold the right Menu Item button for five seconds, and the RC7 will return to the User Menu.

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
