All Electric (Opt. Only); Overview - Holiday Navigator 2003 Owner's Manual

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 systems 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 condition 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 so it 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
properly 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.
The motorhome is equipped with two inverters. The two inverters and the
house battery bank supply an ample amount of power if the system is used
wisely. When dry camping, turn the inverters on only if needed. The inverters
use battery power to supply 120 Volt AC power to operate most of the
appliances, outlets and the entertainment system.
