Sorry this so long but I am trying to give you all the detail at one time.
I read the manuals /did a search and none seemed to address this problem exactly, I still need some help. I have a 2004 Bounder 38N with a 50 amp Smart Energy Management system Model 900 also a Xantrex Freedom 459 Series Inverter/Charger- 4 Trojan 105 always keep full of water and charged. Here is problem; this past weekend while dry camping (no hookups) inverter working just fine- running the generator in the morning and at night to charge the batteries. Using the inverter to watch TV/DVD player/microwave when needed. On the 4th night I turn the generator off after 2 or 3 hours and the inverter did not come on. I pushed the on button on the remote panel and all I got was the on button on the DVD player and the coffee maker on button BLINKING on and off and no power. Cranked the generator up and everything came back on- turned the generator off and back to blinking. I went outside and looked at the front panel of the inverter and went through the troubleshooting led status in the manual and this says it is operating normal. I went to the distribution panel(breaker box) and all the breakers are set. NOW at home- I hooked up to my 50 Amp box and everything is working great. Battery’s are still fully charged –over 13.50. So the charger part is working. Unplugged the shore power and reset the inverter and still only BLINKING again. The led status lights on the inverter show it working fine, still now power out of inverter.
Is it broken or is there something I am missing?

Thanks for your help.

It sounds as though your auto transfer switch is bad. When the generator or shore power is supplied to the coach the switch automatically changes to the supplied power so only one power supply is feeding the coach. In that everything works except the inverter it sounds as though fthe switch is not kicking back to inverter after your generator/shore power is off. There are also solenoids that may be involved; but my guess would be the transfer switch.

My first thought also, the manual for the 50 Amp transfer relay does not say anything about the inverter. Just about switching between the shore power and the Gen. I think it is the inverter gone bad. I emailed Xantrex support and I will post the info. I also email Wolf10 so will will see what he thinks.

We have the same 900 EMS and 458 inverter system in our 2002 Discovery.
First off, if you don't have a set of the wiring diagrams for your Bounder, call Fleetwood Customer Relations with your coaches serial number and they will send you a set.
Now, I cannot say your Bounder is wired the same as our Discovery, however, in our Discovery, the output of the inverter is through the two circuit breakers on the front of the Xantrex 458. These circuit breakers control everything that the inverter is suppose to power. If either of these circuit breakers are tripped, then you would not have power to any device they control.
Please check these breakers before doing anything else.
Think of these two breakers as being an extension of your main breaker panel.
On our Discovery, the Commercial Power, or Generator Power goes through a dedicated 30 amp breaker in the main breaker panel, and then to the isolation relays inside the 458. This isolation section of the 458 either passes the voltage from the 30 amp breaker to the two (15A and 20A) breakers on the front of the 458. If you are not using Generator or Commercial power, then the isolation section allows the inverter to power the two (15A and 20A) breakers on the front of the 458.
While in some units the inverter is wired into the auto transfer relays that select either the generator or commercial power, in our Fleetwood Discovery, this is not the case. The 458 has its own set of relays internal to the device.
The above explanation might be a bit rambling, however I don't know of any other way to explain it.
Think of your system being a 'either-or' device.
With commercial power: the voltage comes in the cable to the transfer relay, then to the main breaker panel, and to a dedicated 30 amp circuit which goes to the input of the 458 isolation relays. From there to the two breakers on the front panel of the 458, and then to their respective devices.
With Generator power: the voltage comes from the generator to the transfer relay, and then as above.
With inverter power: the inverter isolation relays disconnect the 30 Amp input from the main breaker panel and connects its own inverted 120 Volts to the 15 and 20 amp circuit breakers on the front of the 458.
At least this is the way the system is wired in our unit.

I hope my ramblings are of some assistance.

Bill, we did check the 2 breakers on the 458 and they are in the ON position. The main breaker box does have a 30 amp breaker labled INVERTER and it is in the ON position. Unless there is an "inline fuse" somewhere, the unit may be bad. Xantrex support said to plug a light or something in the "buit-in AC plug on the unit"; unless it is on the back of the unit, it does not have one and they don't know which Freedom 458 I have.
Thanks again,

Standard Inverter install has the shore power coming in to the ATS, Generator also comes into the ATS, to the primary distribution to the inverter which has it's own ATS built in to the sub panel to the loads.

You have verified the primary ATS and everything related to and hooked to it is working so forget that as a possiblity

The posibilities are inverter ATS or Inverter itself. My guess (Since you had enough power to blink lights) is the inverter itself.

Call Xantrex


Home is where I park it.

Thanks again,


The 458 does not, to my knowledge, have a "built-in AC plug".
With the age of your RV, I would guess that you probably have the 458-20, and it has a 15A and a 20A circuit breaker on the front panel.
You can download, if you don't have it, a manual on the Xantrex 458 Series Inverter/Charger from
Xantrex 458.
Since you said you checked the lever circuit breakers, did you by chance also push in on the DC circuit breaker, as it can trip, and show no indication that it has?

While I personally have not disassembled my unit, I have been told by others who have had some problems, that there is a fuse on the circuit board inside the unit that might be the guilty device.

Sorry I couldn't be of more help.

Thanks to all, I have made an appointment with Demontron RV here in Houston to take it in for a repair. I have an extenden service agreement good for 4 more months or 1,500 Miles, so I will get in and see. I will let you know the outcome. Thanks to everyone.

Only one month to figure out the inverter/charger was bad and needed replacing. Part of the problem, they said, was the 4 - T 105 were bad because the charger had over charged and thus over heated the batteries. This caused the batteries to "swell up"? Any way we now have 4 new batteries and a heat sensor(which was not hooked up). The extended warranty paid for the Xantrex Freedom 459 Series Inverter/Charger, but would not pay for the damage to the batteries nor the tech's time to figurer out what was going on. Thanks to all who helped.
