Energy Management System

The energy management system (EMS) (Figure 7-16) 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:

Electrical Generator

The electrical generator (Figure 7-17) is located in a compartment in front of the motor home between the
chassis rails on pull-out slides. The generator is mounted on slides for easy access; however, the slides must be
