Inverter woes

[Bob Disney]

Xantrex 2000
The 50 amp service allows all of the coach to work
The batteries charge as needed
When I unplug the coach from 50 amp service

On my RV the inverter seems to be working when you look at the screen above the door.
The light showing the inverter lights up green
The AGS work fine
The 12 volt system works as expected
All the circuit breakers above the toilet are in the on position and not tripped 
Batteries are fully charged

The inverter does not give me the 110 power anywhere in the coach
On the dash screen the legs both show XXXXXXX

Any Ideas?

Heading for Quartzite (any recommended service techs/vendors as I would like to add another solar panel as well)

Bob, Best thing is to find the manual for your inverter and read. I just replaced my Xantrex 2512 modified sine wave inverter (original equipment) with a new Xantrex sw2012 pure sine wave inverter. You have to install a new remote panel, and the thing is pretty complicated, if you don't have your manual in one hand while you push buttons on the remote panel with the other. I do know the inverter has to be in 'enable' mode in order to power the 120v loads in the coach. Not intuitive, but the manual will help. They are available on the Xantrex web site, maybe here under Coach Assist too.

I have been through the manual and it doesn't give me the info I need
I should have said the I have enabled the inverter
I have tried light loads and heavier loads in case there was a minimum draw required, the screen does not allow me to set the low draw setting

Call Xantrex customer service, you will get an actual tech who knows his stuff, very helpful.

    Bob,
 Your Xantrex 2012 inverter/charger should have 1 or 2 push button reset circuit breakers on the side of the unit. Also check the 30 amp circuit breaker in the bathroom.
   I hope to see you in Quartzite. I am conducting the seminar on Friday and my main topic will be Inverter/converters and how to understand and manage them. Fred

[Bob Disney]

I reset the inverter a couple of times and checked the circuit breakers a few times as well
I may need to pull the covers off the breaker boxes and check the wiring from the 50 amp box to the 30 amp box
Could be as simple as a bad 30 amp breaker, it feels solid but who knows
I just don't want to break the inverter doing something I shouldn't

It sounds to me like the inverters internal transfer switch sometimes called a passthrough relay is not doing its job .
If the charger works you must have power from the panel 30 amp breaker .
As Fred explained the two outputs on the inverter have pop style breakers on the side of the inverter ( they should be pushed in)
Those two breakers work on both shore power ( pass through) and inverter power so if you have power on either source the breakers are ok.
If the passthrough relay is defective or stuck (contacts welded together) you will have only one mode of operation.
They usually stick in the shore power mode (pass through) as this is the mode they spend most of there life in.
Sometimes when there stuck you can free them with a good thumb with a rubber hammer ( not likely recommend in the manual)
Hope this helps

Bob,
If you haven't yet, try the inverter reset procedure shown in this thread.  http://beaveramb.org/forum/index.php/topic,8477.msg58912.html#msg58912

The inverter reset procedure is from my 2005 PT owners manual and is for the original equipment Xantrex RV2512 modified sine wave inverter. The reset procedure is not in the original Xantrex manual. Not sure if the procedure applies to any other inverter.

[Bill Lampkin]

Bob, My new inverter is a Xantrex Freedom SW 2012 pure sine wave inverter. I had to replaced the original GS series remote panel with the new SCP remote panel to work with the new inverter. I also installed a new AGS; The old RV2012 inverter had the AGS included in the inverter but with the new inverter you have to install a new AGS module. I have yet to hook up the AGS.
This is a long way around to answer your quesion, but if you have 120v when plugged in to shore power but no 120v when NOT plugged into shore power, I still think your issue is with the programming of the inverter  and or AGS. If your inverter uses the GS control panel or the SCP panel, I think its worth a call to Xantrex to help you figure it out. There are so many models of inverters, it gets difficult to figure out which is which.

[Bob Disney]

 I should have stated the Generator does power the coach when running
also the AGS does start as programed

[Bill Lampkin]

The inverter takes 120v ac from either shore power or generator and the inverter acts to 'pass thru' this 120v 30a power to the loads that are fed from the inverter supplied breaker panel. The transfer switch is what selects shore power or generator power; the inverter doesn't 'know' if it has power from shore power or from the generator. Since all works with the gen on, I still believe your inverter is not set up correctly. Do you have the original equipment modified sine wave inverter with the RV7 GS remote panel, or has it been replaced with the newer, pure sine wave inverter with the SCP remote panel?

[Bob Disney]

I believe it the original
How do you tell the difference?

[Bill Lampkin]

See if your remote panel is labeled RC GS7; if so, you have  an original modified sine wave inverter.

If I could post pictures, one would be worth a thousand......

You can look it up on the Xantrex website to see which inverter you have.

[Bill Lampkin]

If yours is the RC GS (forget the 7, my error) remote, the green light is solid when on shore power and starts blinking when shore power is disconnected and the inverter is drawing battery power to make 120v for the coach. May I ask as to how this trouble started? New (to you) coach? We all have a million questions when we first get a coach (I still have a thousand questions, easy!). Did some service to the inverter occur or other change to the electrical system? Has the inverter worked fine before? What changed?
