2. Auto LBCO
Automatic Low Battery Cut Out (Auto LBCO) prevents the inverter from
draining the batteries below 10.9 V dc (with no load on the output). When this
mode is enabled (ON), the inverter shuts OFF when the batteries reach
10.9 V dc. When it is disabled (OFF), the inverter remains ON until the batteries
reach a voltage of 8.5 V dc, at which point the inverter will shut off. When ac
input is available again, the inverter automatically resets and begins charging the
batteries. The default setting is OFF.
Press the RIGHT arrow (Settings) to select the desired function. After
selecting, press the DOWN arrow to scroll to the next menu or the UP arrow to
move to a previous menu.
3. Battery Capacity
Battery Capacity refers to the battery’s reser ve capacity in amp-hours. The
RC7 approximates the battery state-of-charge (SOC) and run-time then
estimates the battery capacity (Auto) over several charge/discharge cycles.
However, setting the capacity manually assures a more accurate initial SOC and
run-time calculations. The default setting is Auto.
The Battery Capacity setting also sets the absorption charge time where the
batteries are charged at the bulk voltage.
Auto ------------ 110 minutes (1.8 hours)
125 A hrs------ 60 minutes (1 hour)
250 A hrs------ 90 minutes (1.5 hours)
375 A hrs------ 120 minutes (2 hours)
500 A hrs------ 150 minutes (2.5 hours)

6. Set Shore Power
The inverter monitors the ac power being drawn by both the battery charger
and the ac loads connected to the inverter. If the current draw approaches the
shore power circuit breaker rating, the battery charger reduces the amount of
current supplied to the batteries to provide the maximum current to the ac loads.
Set Shore Power ensures the battery charger does not exceed the shore power
circuit breaker rating. This setting should match the shore power or generator’s
circuit breaker rating. The default setting is 30 amps.

RC7 and RC7GS System Status Displays
The RC7 and RC7GS remote controls display the operating mode and
system status by lighting one or more LEDs located on the front panel and/or by
displaying a message on the LCD display. The four LEDs reflect the same
information as the single tricolored LED on the inverter/charger.
There are four types of system messages:
• AC source messages
• Inverter messages
• Charger messages
• Error messages
AC Source Messages
AC source messages appear when alternating current (shore power) is
present. In addition, the RC7GS ac source messages describe the current
activity, if any, of the generator.
1. Waiting for AC
Anytime the inverter is OFF and ac is not present, the LCD screen displays
“Waiting for AC.”
Figure 33
Waiting for AC
2. Genset Status: Pending, Cranking and Genstart
When the RC7GS is setup to start the generator for a specified condition
(SOC or battery voltage) and that condition has been met, the LCD displays
“Pending Genstart.”
Genset Status:
Pending Genstart
Genset Status:
Cranking Genset
When the initiating condition (SOC or battery voltage) has occurred, the
Pending Genstart message is displayed for approximately two minutes awaiting
a change in the condition or a manual override. If neither condition occurs, the
RC7GS attempts to start the generator and displays “Cranking Genset.”

types could permanently damage them.
CAUTION: Do not attempt to remove vent caps on AGM batteries. Doing so may
void the warranty.
CAUTION: All dc loads should be disconnected dur ing the equalize charge
period due to the higher voltage applied to the batteries (15+ volts dc). Refer to
the inverter manual Equalize Charging section for details.
NOTE: The equalizing mode is defeated if GEL cell is selected as the battery

Storage Checklist
NOTE: This applies only to the RV Ser ies inverter/charger with RC7GS Remote.
Proper storage procedures extends the life of the batteries and ensures the
coach is ready for operation when needed. The following checklist is for battery
related storage activities.
Preparation for Storage
Interior Storage
• Check that all batteries are fully charged.
• Disable the Auto Gen. feature.
• Configure the RV to the correct shore service settings.
• Connect the shore power cord to a live outlet (confirm it is live).
• Switch the RV unit OFF using the remote’s On/Off push-button
(charger only mode).
• Switch OFF all unnecessary ac and dc loads.
WARNING: DO NOT STORE THE COACH INDOORS WITH THE AUTO GEN
START FEATURE ENABLED. THE GENERATOR PRODUCES DANGEROUS
FUMES WHEN IT IS RUNNING.
Exterior Storage
For exterior storage, follow the same steps as above. If shore power is not
available, enable the Auto-Gen Start feature and ensure that enough fuel is
available to run the generator for charging the batteries. The generator will
automatically start and stop, depending on the battery’s state-of-charge.
