Inverter-on or off?

With my generator running and powering the A/Cs I noticed that the outlets hooked to the inverter, TVs and microwave, was not working. When I push the power button on the control panel for the inverter the outlets are powered. All other outlets are operating normally.

Shouldn't all outlets operate on AC power when connected or on generator. Do I need the inverter on or am I missing something here?

Thanks, Mark

You shouldn't need the inverter when on shore power or geny. Have you checked your breakers? Inverter has it's own main (sorta)..

So please help me think this through. The breaker on the inverter is not tripped. It appears that the circuits connected to the inverter are connected only to the inverter and not the generator or shore power.

The transfer switch appears to be working when I switch from generator to shore power or vis a versa. So what you are telling me is that the inverter control on the main panel should have no effect when on AC power? And for the time being, is there a downside to leaving the inverter on while on power?

Thanks

There should be a breaker in your regular panel that is for the inverter. Only downside is converter may not keep up with the inverter load and you will kill your house batteries.

My 2014 Seneca has a separate small breaker panel for the inverter-supplied outlets. My Xantrex inverter has its own small transfer switch that decides whether to send inverter power or shoreline/generator power to those dedicated outlets. If shoreline/generator power IS available, that inverter transfer switch defaults to shoreline/generator power even if the inverter switch is turned on. My inverter display will only show minimal power consumption, probably just what it takes to make 110-volts AC internally even though it is not being utilized by the system.

In my main "power distribution" box (110-volt breakers, 12-volt fuses, and converter) I have a 15-amp breaker that supplies shoreline/generator power to the inverter transfer switch. If I turn that "off" with the inverter turned on, the connected devices (microwave, front, and bedroom TVs) will work, supplied at that point by inverter power. The inverter display changes and immediately starts showing battery amps being drawn. So like Grumpy said, if that main panel breaker is off or bad, you will not get shoreline/generator power to the inverter transfer switch for it to "see" so it could default to that source. Also, it is possible the inverter transfer switch itself may be bad or miswired, causing it to not default to shoreline/generator power even though it might be present. I also agree with Grumpy in that those circuits running strictly on the inverter (especially using the convection microwave), you may overtax the batteries and converter trying to keep the batteries up.

If my inverter breaker was off or bad, or the transfer switch was not switching, I suspect I would have symptoms like you. But I preface all this on my 2014's wiring. They may have somehow changed the layout and components on your new unit. But I think Grumpy's and my theories are correct, just need some troubleshooting to determine the cause. I wish I could have 15 minutes with your unit!

That's how my 08 was too only the inverter breakers were on a separate buss inside the the regular breaker panel.

I checked all breakers and none were tripped. It seems like my inverter transfer switch is not recognizing when it is receiving ac power.

Is the transfer switch something I can access and check?

I wish I could grant that wish Rob. There are so many cool mods you have done and would love to have you mentor me on RV 101 and 102. I may need to coax you to come to Florida when you are buried in snow this winter.


We leave are leaving for three months a week from Thursday and I am scrambling to get every conceivable thing done. Adding to this is the brutally ridiculous heat down here. I am dripping before I make it to the RV.

On a positive note, the RV house is almost done and will be inhabitable on our return. That will make it much more pleasant to work on in the shade.

I am going to tell you that my head is spinning from reading all the manuals. According to the manual, the inverter operates in "pass through" mode when connected to shore power or the gen. This is working well for me since I exclusively dry camp. There are however multiple settings that can be adjusted, which I did not look at any further. I am thinking you need to leave inverter on, and perhaps one of those settings has been changed and needs changed back.

Nice Seneca house!!
