The house system is charged by several sources. The alternator charges the system
through the isolator when the engine is running. As mentioned above, the isolator keeps
the house system separate from the chassis system, preventing the chassis battery from
being drained by the house appliances. The Freedom 10 inverter/converter provides power
from a 120 VAC source, either the generator or shore line. It operates automatically
according to the presence of 120 VAC power.
The 20 watt solar panel located on the roof of the coach assists in charging the house
batteries during the day, when direct sunlight is present, via a solar isolator.
The house battery system provides power directly to the inverter. It serves the circuits
that connect to the interior and lighting. These include the ceiling fans, furnace, water
heater, water pump, cargo lights, and refrigerator. They are connected directly to the
house batteries through a 105 amp breaker located under the entry step on the frame
rail. A fuse panel is located next to the 120 VAC breaker located either under the bathroom
sink or in the lower galley bar cabinet. The house battery system is also connected to the
chassis system through the boost switch.
The fuse panel is separated from the batteries by a breaker and a relay. The switch to control
the relay is mounted on the firewall near the coach entry. The breaker is located under the
entry step on the frame rail.
The strength of the batteries can be checked using the Coach Monitor Panel. The monitor
can only give a general indication of the charge level of the battery, but is an important
tool for your power management.
You have plenty of options to assist your power management. There are three ways to
recharge your batteries:
1. Engine Alternator (while engine is running)
2. Freedom 10 Inverter/Converter (shore line or generator)
3. 20 watt Solar Panel (trickle only)
NOTE: One factor to remember is that recharging time is greatly affected by the
load. The less drain from lighting and accessories, the faster the batteries
will recover.
