TIFFIN MOTORHOMES –PHAETON® Chapter 7 ELECTRICAL FEATURES
When the inverter is turned ON, it operates either by “Searching” or “Inverting,” depending on the connected
AC loads.
SEARCHING : When the inverter is first turned ON, the automatic Search feature is enabled. This feature is provided
to conserve battery power when AC power is not required. In this mode, the inverter pulses the AC output looking for
an AC load (i.e., electrical appliance). Whenever an AC load (greater than 5 watts) is turned on, the inverter recognizes
the need for power and automatically starts inverting. When there is no load (or less than 5 watts) detected, the
inverter automatically goes back into search mode to minimize energy consumption from the battery bank. When the
inverter is “Searching,” the inverter’s green LED flashes fast.
INVERTING : When a load great than 5 watts is connected to the inverter output it “inverts” the DC power from the
battery and supplies 120 VAC power to your sub-panel. The inverter’s green LED flashes once every 2 seconds
(medium flash) to indicate it is inverting. The amount of time the inverter can be inverting and provide power is
directly related to the amount of AC loads that are connected and the capacity of the battery bank.
For further reading and additional information on the above, please reference your inverter/charger manual
that will be found in your Owner’s Information Package.
Energy Management System
The energy management system (EMS) (Figure 7-11) distributes all the
120VAC power throughout the motor home, whether it comes from shore
power, generator, or the inverter. The EMS monitors the incoming power,
and manages the power to reduce circuit breaker tripping. It does this by
momentarily shedding power to the loads under its control when the user
turns on other more critical appliances in the motor home. EMS restores
power when the appliance is turned off. The EMS panel displays the status
of incoming power and the controlled loads.
When coupled with an inverter, EMS reduces battery charge rate
prior to
shedding any loads. Working together, an inverter assist feature is
available. Normally the inverter is at rest when shore power is
available. EMS utilizes the inverter and the coach battery bank to
smooth out peak load demands. In one sense, the inverter will
temporarily provide power to some of the appliances, prior to
shedding any loads.
The following lists the load shedding chart:
