What he is describing is a power share that is available with Xantrex/Heart Interface that can be set to limit the amount of amps that the Xantrex will use when charging the batteries. Default on ours is 30 amps. When on 50 amps for an extended period of time, I do set it to 50 amps because we have more than enough power. During the summer when we are traveling, I usually set it for 20 amps if we are on 30 amps, or 30 amps if on 50 and then not worry about it. When plugged into a 20 amp circuit (driveway parking at a relative's place or parking at a repair shop), I set it to 5 amps to just keep the batteries going so don't trip a breaker.

This is not an EMS - it only affects the inverter/converter; doesn't shed power to any other appliance, etc. in the rig.

And to answer the original question, no it doesn't affect how many KWH are used, just the length of time it takes to get it batteries charged up - - which is not long if you are plugged in and staying for a long time and they are at float level.

I'm not real sure what type of equipement the op has or is asking about.... his description seemed too cover both?

Many of the responders. Seem to be losting about their particular rigs as gospel...

Mine (a 2008 monaco) has:

An energy management system, with butttons for 50, 30, 20, and 15 amps. It automatically sets 50 or 30, and I can manually set 20 or 15. This device controls load shedding, how much the rv will take from shore power.

I also have a panel for the magnum inverter/charger. This thing has. A 100 amp charger, and can use a significant amount of the available shore power. In it's ,menu swettings, I can tell it "what shore power" I have, and that will change it's max charge current, which will affect what the ems system will let me run.

On a 20 amp shore power hookup, I cannot run an a/c unless I also select a lower settiing on the magnum's panel.

And yes, when I do that, the charger uses less electricity.

The bottom line is this: IF it is infact an inverter/converter, and the batteries are full, or nearly so, which they should be after 2-3 hours in the park.. NO DIFFERENCE.
Home is where I park it!

We have a Xantrix inverter with an RC7GS control panel. I can set the charging circuit to 30, 20, 15 or 5 amps depending on how much I want the charging circuit to pull. It has no effect on the amount of shore power available for the rest of the RV other than leaving more for normal use.
When I store the rig at home I set it for 5 amps and leave it connected all the time.
