converter putting out 14.2 volts

We just returned to Arizona from our summer home in Alaska. While in Alaska I rewired my TV electrical system to provide enough power to the trailer to run a 12 volt portable freezer as well as the refrigerator.
When we stopped at night the battery voltage indicator on the solar controller always indicated fully charged batteries.
I had an occasion at a full hookup site to turn on the inverter to confirm it was operational. When I came back in the trailer a bit later the indicator on the controller was flashing a "check" warning message. The indicated voltage on the controller with the inverter on was 14.2 volts. Inverter off voltage reading was normal. I checked the battery electrolite and had slight bubbling so I assumed I was in an over charge condition and discontinued using the inverter for the remainder of the trip.
Does anybody have information or experience with this situation? Is there an adjustment on the inverter that can be dialed in? The inverter appears easy enough to replace but just thought I would put the issue and question out here for any input prior to buying a new unit.
Thanks for any responses.

An inverter takes in approximately 12 volt DC power from the battery, and provides 120 volt AC power.
A converter takes in 120 volt AC power ("shore" power from the campsite outlet) and produces approximately 12 volt DC power to run stuff in the trailer and charge the battery.

It sounds like you mean that the converter produced 14.2 volts, not the inverter. Right? Once that is clear, we can make sense of the rest of the situation (which is probably perfectly normal).

Yes,My mistake. I am indeed referring to the converter that is part of the distribution panel which is stock in the 09 17' trailer.

I see no adjustments on the WFCO converter if that's what you have. Here's the page from the manual that shows how to properly check it's output. I'm suspect as to whether it's really bad due to the electrical work you've done. This will prove whether the converter is bad or it's something else.

Thanks,
Yes I have checked the voltage at the terminals indicated as well as at various 12 volt outlet points in the trailer. All read 14.2 vdc with converter on and 12.75 vdc with converter off. RD

If you disconnected the wires as mentioned then it does look like the converter is messed up. I bought one in the past from BestConverter, they also carry another brand that is a direct replacement for the board which is worth considering as WFCO's are not top notch units. Randy is the owner and can help point you in the right directions if you are doing this yourself.

Thanks,
From what you wrote I am assuming there is a board that can be replaced? That would be excellent as opposed to replacing the entire converter.

Randy would know for sure, I had swapped an Elixer board with a WFCO in my 06 Starcraft. Should be something like this PD4655MBA WildKat 55 Amp Main Board Assembly for WFCO 8955 or Parallax 7155 (Includes 4600 Remote) depending on what you have in your trailer. See if you can find a model number on it. I'm sure there are many places to get such, BestConverter happens to be the one I know of.

Thank You,
I will pursue this. This looks like a doable solution. RD

Bob's right Robin. Randy sells upgrades/retrofits for the WFCO. It changes out the mainboard and charger. Several have done it, with either the "Boondocker" board or the Progressive Dynamics. Last time I spoke to Randy he liked the PD better, but give him a call.
