Xantrex inverter won’t turn on

Hi,
My Xantrex inverter will not turn on.

I have a Freedom XC series inverter charger on an Entergra Odyssey RV.

Product part numbers: 817-1050 817-2080

When I’m connected to shore power, both green indicator lights are on and the bottom light is red, but I’ve not seen an error code. All of my rig power works, and the batteries seem to be charging just fine.

When I’m disconnected from shore power, the inverter will not turn on.

Things I’ve tried to troubleshoot:
1. Tried the reset button, but nothing happened - it was the 20A supplementary protector with reset button - didn’t seem like that was connected to anything but I tried to hold for several seconds to see if it would reset.

2. Visual look to see if there was anything obvious out of place - nothing obvious.

3. There is an Inverter fuse, but not sure I know how to determine if it’s blown or not (photo attached). Not sure how to determine if there is flow across the fuse or not.

Any help or suggestions would be greatly appreciated

That fuse is on the DC side of your inverter. This part is where the charging current goes to the batteries.

Your control panel may have a on/off function for the inverter. That would be the first thing I would check.

I reset my inverter (which is older tech) by turning it off for 15 seconds at the main AC panel. Then turning it back on.

To check that fuse, put a meter on each side to ground, you should read battery voltage on both sides. When the shore power and generator are both off.

If the unit is charging the batteries, the fuse is good.
Inverter/chargers use the same cables for both funtions.

Yogi Berra once said that you can tell a lot just by looking. In the case of your inverter/charger, look at the control panel. There is an indicator light that shows if your inverter is receiving AC power (AC In), if your charger is on, if your inverter is on, and the levels of power in your system. The panel below represents what mine looks like when all is well. The manual for the Freedom Control Panel is listed below the photo and provides detailed explaniations about the setup and monitoring capabilities of the control panel.

The "trouble" I have had with my inverter has always been caused by battery condition. The inverter has a low voltage cutout that prevents the charger from operating if the house battery voltage is too low. This past summer, when I was arrived at a new campsite, I'd run my setup (jacks, slides)
before I got out of the coach. The process would suck enough juice out of my 7 years old batteries that the inverter would alarm and not charge after plugged into shore power. I could reset the inverter by using the inverter breaker in the main panel, and see current levels in the DC Amps column go over 100 amps (100 amps is the alarm level of my inverter/charger) as the charger tried to respond to the battery condition. The charger would shut off in a couple of minutes. I learned most of this the hard way. It took a couple of stops before I understood what was happening. Since all my DC power comes form the batteries, and the batteries where not charging, equipment would quit working. The first thing in my coach that would quit working when the battery levels got low was the steps. I circumvented this problem by using an auttomotive charger on the house batteries to get them back to normal levels. New batteries are in my future.

Status - not much info yet

I appreciate all of the input I've received. Some additional info:

1. The Inverter/Converter does not turn on when I'm not connected to shore power or have the generator on. So, the control panel is blank when I have no external power (shore or generator) connected.

2. I've ordered a volt meter so will confirm where I have readings and where I don't.

3. I looked at my breaker box and there is a GFCI breaker that is not responding when I push the test button on it. It's different than any GFCI breakers I've seen on houses. That may be the next area to investigate.

Thanks again - will post results once I have readings from the volt meter.

Metering is a good plan.

"3. I looked at my breaker box and there is a GFCI breaker that is not responding when I push the test button on it. It's different than any GFCI breakers I've seen on houses. That may be the next area to investigate."

GFI will not test or reset unless there is 120 volts to the input. So it is behaving normally.

Trouble changing fuse

OK - so I confirmed that it was the fuse that was blown by putting my meter on each side of the fuse.

I ran into trouble changing the fuse. I was concerned about the power from the batteries - so I disconnected the battery cable on the positive post - changed the fuse -- but ran into significant trouble trying to reconnect the battery cables.

When I tried to put the red cables back together (batteries running in series) there was a arc, tried it again and the saw a bit of a flare coming from the Inverter. ::I think I fried my inverter::

I had rig power system off, had breakers for Inverter and AC off, but hadn't disconnected any negative leads. I also didn't turn off any breakers at the breaker box, but I had turned off the rig power so not sure breaker box would come into play.

Any suggestions on the steps I should take putting this all back together without setting the rig on fire or being electrocuted?

I'll go try and get a photo... thanks in advance for the help

I might expect a small spark, especially if the caps in the inverter are discharged, the spark would just be them charging, but if you saw something inside the inverter flaring, that's not good. Sounds like a loose connection or a defective component, which could explain the blown fuse. Can you get a picture of the area inside the inverter that arced? I'd look very carefully inside the inverter, with the batteries disconnected, as you have them, for damage/loose stuff.

Thanks Harry, I’ll have to take the cover off of the inverter tomorrow. I think I’m close to calling in some professional help. I worked as an electrician’s apprentice on and off during lay-offs from Lockheed during my early youth so I’m comfortable with house wiring, even adding breakers, etc. However, I’m not at all familiar with how everything is connected between the solar, the inverter, the house batteries, the coach battery, the breaker boxes, the ATS, etc. etc etc.

If I were to connect everything back if I don’t see any damage in the inverter, would you recommend disconnecting the negative battery? Or should connecting the positive posts have worked the way I tried?

I agree, maybe this was the cause of the blown fuse…

Appreciate you taking the time to help.
