110 volt issues

Ok....when our 2000 Allegro Bus is hooked to shoreline ALL 110 outlets work....when we run the genny ALL the 110 outlets work...BUT when I run the inverter only we only have 2 110 volt outlets on the drivers side and 2 in the front that are "hot"....all the others are "dead".
I changed the ac breaker....no help. I checked the 12 volt fuses...no help. I am now looking toward the actual inverter...but all inverter lights are green.
I must be missing something obvious....another breaker/fuse?

You don't mention your coach and year, but I'm sure it's working as designed.

Half of the sockets are typically circuits that run thru the inverter. The other are not, and are only connected to the main circuit breaker panel which are hot only with the generator or shore power.

In my case, the PS sockets, Kitchen, Bath, and Entertainment are on the inverter and work all the time. My DS sockets (by the sofa, and bedroom) are only available via generator or shorepower.

Since you had your circuit breaker box open and replaced a breaker, if you look closely it is not a typical breaker box. It is split into two pieces, with the 2nd piece being a 'sub-panel'. The first half of the box has the circuits that are only powered from shore/genny, including the 120 power feed TO the inverter. The wire coming back FROM the inverter, plugs into subpanel section....and that is what powers the remaining breakers in the box. You should see that the circuit that is 'not' working in your scenario(while in inverter mode), is on the main half of the breaker box.

I strongly suspect what you are seeing is a bad case of "Working as designed"

Inverters normally only power selected outlets.. Those outlets are:
#1: Television and support electrioncs.. And in some cases if you have multiple TVs ONLY the main TV not the one in the bedroom.

2: Make the inverter a bit bigger and you add the GFCI outlets, these are usually the Bathroom, Kitchen and patio.(Outside) NOTE the outlets up front that work.. those are on the TV circuit.

3: Bigger still (Minimum 1500 watt 2000 better) Add the Microwave.

And on some rigs that are FACTORY wired with an inverter there are two outlets in the Refrigerator compartment, ONE is inverter powered and is for the ice maker, the other is for the Fridge on A/C.
Home is where I park it!

Our Beaver was originally wired with a 2kW inverter (we now have a 2.8kW one) and all but 2 outlets are powered by it. Even the microwave had been powered by the inverter but we "stole" that circuit and now power our residential fridge off of it.
