ALL ELECTRIC (Optional)
This material in this section covers items that are particular to the All Electric motorhome. This is
meant to augment the rest of the manual and therefore is not a substitute. The key for the All Electric
motorhome electrical system to function properly is understanding how the AC and DC electrical sys-
tems interface. Become familiar with the inverters and programming the remotes. The generator must
be operating properly for of the Automatic Generator Start feature to function. The charge condi-
tion of the house batteries is equally important. Keep the inverter owner’s manual in the motorhome to
be used as a reference.
The motorhome does not have propane and operates much differently than the standard propane
equipped motorhome. All appliances operate from AC, DC, diesel or a combination thereof. For the
electrical system to function, the 120 Volt AC and 12 Volt DC power supply sources must be operating
properly, especially the generator. When shore power is not available, appliance operation relies
exclusively on the generator, inverter or batteries for power. The inverter Automatic Generator Start
feature should be enabled when shore power is not available to help prevent dead house batteries.
Using the inverter as the 120 Volt power source can quickly consume battery power. Do not allow the
batteries to discharge lower than 50% SOC (State of Charge). The batteries ability to obtain a full state
of charge, and the number of discharge cycles, reduces each time a severe discharge occurs. Eventually
the batteries will no longer accept a charge, resulting in electrical system malfunction or total system
failure.
The SOC of the batteries determines the length of time the inverter can operate from the batteries.
Use arithmetic to calculate inverter run time or DC power loads. When dry camping closely monitor
interior light use. Some lights operate only from 120 Volt AC.
NOTE:
One inverter will need to remain on to operate the refrigerator when dry camping
CAUTION:
The shore power requirement of an All Electric motorhome, in most situations, will
exceed 20 Amp shore power service. It is strongly recommended to hook to 30 Amp
service or start the generator.
