House Batteries

While Traveling:
While traveling, the refrigerator may be operated keeping the refrigerator
contents cool. The electrical combination of the engine's alternator and the
inverters AC output supplies the power necessary to operate the refrigerator on
120 Volts AC. Disable this feature when the engine is off. House battery power
is quickly consumed when using the inverter to operate the refrigerator on AC
electric. Hook to shore power, start the generator or enable the Automatic
Generator Start feature. To conserve house battery power, turn the inverter off
when not in use.
NOTE: All Electric coaches will come standard with two solar panels
installed on the roof.
The battery bank consists of five Type 8-D 255 amp hour AGM (Absorb
Glass Mat) batteries. The batteries are hooked in parallel. Voltage readings are
the only way to accurately determine the state of charge of the AGM batteries
as they are a sealed battery. Voltage readings are most accurately measured
after three hours of battery inactivity. The length of time it takes to charge the
battery bank to a full state of charge will vary with the following conditions:
• How deep were the batteries discharged?
• What other DC loads are applied during the charge cycle?
• What is the actual physical condition of the batteries?
• Inverter remote programming.
It may take a number of hours or days, with the motorhome hooked to
shore power 24 hours a day, to charge the batteries to a full state of charge.
During the charge cycle, one inverter may be in Bulk charge while the other is
in Float. This is normal, as the two inverters though electrically linked through
a common shunt, do not have a common link between their internal chargers.
