We have a 2006 Dolphin model 5320. We have read through the manual on the inverter and need some clarification. After turning on and setting the battery type the LED lights show as follows: solid for inverter fast blinking for charge. There is AC power connected to MH with just 120 volt power cord. The confusion comes when the book says this is normal but trouble shooting problems says if AC power available there is no charge. This came from the fact we have no power to TV's. We have checked all outlets their good, all breakers good. Hopefully someone can Help.

Does the transfer switch "click" (or thunk) when you plug in the shore power? No power to the regular AC outlets (when the inverter is OFF) would indicate that the transfer switch hasn't detected that there is AC. By the way you basement HVAC should be off because it would pop the circuit breaker on the 120V (probably 20A) circuit.

I have a trickle charge on the chassis battery because the Xantrex "is not supposed" to charge it.

you might want to check your GFI's to insure one isn't popped. Check for it in the bathroom if you don't know where it is. Often one GFI controls many outlets. Also as a means to check that you are getting shore power there is usually at least one outlet that is not on the GFI and doesn't go thru the inverter - mine is in the engine compartment.

As you dig deeper, You can also check the voltage at the input to the Xantrex. There is a small plate on the front you can remove with two screws and then with a volt meter check input and output voltage.

There is a xantrex troubleshooting guide online, if you can't find it shoot me a note and I have it somewhere. The folks at xantrex are pretty good at helping troubleshoot over the phone.

Do you know if the Xantrx is repairable?

you might try re-booting the inverter. Shut down AC to the coach, hit your disconnect 12volt switch then disconnected either the black or red terminal at the invereter, wait 10 minutes then re connect the lead turn on 12 volt then AC power.

If you have shore power you can turn the inverter off and should still have power to tv. Try a different plug in the cabinet. The tv plug has an interlock with the ignition that may go bad.

nanc1860clif,

There are places that repair them. If you are close to Atlanta, I had mine repaired and very reasonable, but shipping cost is so high it is prohibitive to ship for repair vs new cost of app. $900. I suggest downloading the xantrex troubleshooting guide and following it in detail to determine if it is your inverter or other issues.

There is a small fuse (F2) inside the inverter than can go bad.. I think it is a 3amp. you can test it externally, but have to remove the inverter and cover to replace it if needed.

I suggest pulling off the front plate and testing for voltage there when either the generator is running or plugged into shore power. .. and go from there. Also find use a light or somthing to test other 110v plugs to see if you have power.

The inverter also has an internal transfer switch which can prevent it allowing shore power from reaching inside the coach. At least the way mine is wired, it can. Took me 2 weeks to completely troubleshoot my inverter.

I agree with rjsupersonic. Worked for me once. I removed shore power and dis-connected batteries , including engine. I waited 5 minutes + then re-connected
batteries then shore power. Then it worked correctly in my case.

Thanks everyone. After trying all the suggestions we still were unable to fix. We did find a Xantrex dealer who is going to repair. He believes we fried a controll board.
