Our 07 Discovery has a Xantrex Freedom 458 that currently has a control board issue. The remote panel is good (tested with like inverter) but not communicating with my Xantrex. I can't control the inverter via the remote panel or the buttons on the inverter. When connected to shore power the converter will charge the house batteries and when disconnected will invert. I'm going to purchase a new control board in the near future.

The problem I'm having is that the converter will NOT fully charge my 4 Interstate house batteries (4 6volt wet cells). I verified this using a proper glass temperature compensated battery hydrometer.
When I was in Quartzsite my Classic charge controller would fully charge them after I programmed the proper charge parameters. The absorb voltage programmed in the Xantrex is not high enough to fully charge the Interstate batteries.
I'm currently under trees so I disabled the charge controller.
What I'm looking for is a programmable charge controller that I can also use to de-sulfate.
Any suggestions?
Thanks

Robert,

What is charge voltage when first plugged in-- i.e. bulk charge voltage?

What is voltage after 10 or more hours-- i.e. float voltage?

“I'm currently under trees so I disabled the charge controller.”

Disabled the solar system? Why would you ever disable a solar system? Some solar charging even on overcast days, shade etc.

Classic? as in Midnight Classic brand solar charge controller? This one should easily charge, equalize and desulfate.

Otherwise I recommend Morningstar controllers.

1. Have you tried disconnecting 120 and 12 volt power to the 458 for 10 minutes and reconnecting? THAT reboots communication errors on a Freedom.
2. You do NOT have a Converter. The Xantrex is a multi function Battery Charger.
3. If you determine the Xantrex does need a board, on a 13 year old Inverter, I would instead opt for a NEW Xantrex, which will also require a NEW remote panel as your panel probably will not function with the current Freedom's.
4. Is it Possible that your Battery Temp sensor system on the Xantrex is malfunctioning causing your full charge error? Doug

Thanks for the reply's

When I stated converter I was referring to the Charging side of the Xantrex. Sorry for the miscommunication

Brett
If the xantrex is shut down & then restarted the voltage goes up to 14.1 and eventually floats to around 13.3

As stated above I'm under trees so the solar is not doing much of anything thus the reason I have it disabled

Doug
Been thru the powerdown of the Xantrex to try and get the communications back to the remote panel. As stated above I should have said Xantrex charger rather than Converter. Very aware of the age of the Xantrex. IF I HAD the money I would indeed purchase a NEW inverter. I am looking to replace the battery temp sensor.

Looking for a charger. Any suggestions?

Thanks

This converter will get your GC2 battery full:

Which remote controller do you have? Basic controller setup you can set amp hours of your battery bank, power share and equalize.
I have a Link 1000 controller which can do much more than this but it is out of production, same thing for the Link 2000.

May just need a new basic controller, around $150

The control board in the inverter has an issue, not the remote panel.Thanks for the reply.

I had the same problem where my batteries would charge but the inverter would not work and I couldn't get the inside panel to do anything.
I tried turning on the inverter on the unit itself and nothing happened. I was about to take it out and replace when I started messing around with it a little more. I found out that you have to hold the power button down on the inverter for 5-10 seconds before it would turn on, not just press and release. Mime fortunately did turn on then.
I decided it was probably just a bad remote controller inside the coach. I removed it and ran a short cord (just an old phone line cord) from the unit inside the bay to the control panel and it worked! So in my case it is a bad cord and I just need to run a new one.
Hopefully yours is this simple or this information helps someone else in the future
