That's not possible.....unless your inverter is connected to your chassis battery(s).
RV inverters take 12VDC and make 120VAC... (an "inverter" that is not connected to a 12VDC power source can/will do nothing).

I even turned off my chassis batteries. The only way I got it to stop was take lead off inverter

When I turn house batteries off and chassis batteries off there is still a light on inverter

Travelwrench - on my 05 Excursion overhead panel, in addition to turning off the house and chassis batteries, I have a switch to turn the inverter off. Is there a switch on your overhead to do this?

Just on the panel soft button I can turn off but in a little while it turns back on. Does this have any to do with the power management system. Cause when I hook up to 30 amp shore it shows gen. I talk to those guys and had me reset but didn't matter. He said could be bad board

So does the intellitec sms have anything to do with the xantrex inverter

Your inverter/charger is probably direct-wired to the batteries so it can charge them whether the disconnect is on or off. That is fairly typical of Fleetwood coaches with standard inverter/chargers. The inverter itself, or its remote, should have an on/off setting for at least the inverter function. My Xantrex RV2500 is always active for charging and the "Off" position only stops the inverter function from operating. It will still show charging statu, etc., when shore or genset power is on. Yours (a Magnum inverter, I think?) may be different.

The EMS (power management) doesn't affect the inverter operation. If you see Gen on the Intellitec display when connected to shore power, it means the EMS is getting a +12v signal from the genset start switch circuit. That's how it recognizes the genset is running. You may also have lights on the genset remote start switch if this happens. It means something is miswired or shorted. It's not serious, but the EMS turns itself off (no load management) when the Gen light is on.

As I stated earlier there is a button to turn invert on and off but it's just a soft switch. I am working in my coach now with no shore and house batteries off. All of a sudden the inverter light comes on and is sending power out. I can then turn off but it will come on again in awhile. The only way I can stop it is take the lead off inverter so when I store it
