Just to clear things up:
The transfer switch has two inputs (gen/shore) and one output.
The output of the transfer switch goes to the inverter. That way the batteries charge from either gen or shore.
There is a leg from the gen that powers a couple of outlets that does not go through the inverter.
The inverter is a Xantrex SW 2000. It has 1 input and 1 output. There are 4 lines connected to that inverter output. The microwave is on one, the lights are on another, I presume the 2 A/Cs have their own lines as well.
The inverter powers the whole coach well. But the A/C and fan don't come on at all from inverter power. The A/C only works from gen or shore. It's possible that the A/C is running on a leg that does not go thrpugh the inverter.
Either way, when the lights flicker the A/C also thumps.
i think you are over loading one side of your 220ac then
if what you are saying is right you are pulling 2 AC units on one leg of the 220 ac and then giving what mood the inverter is in pulls a high load to no load
OR if a ac unit is ran in to the inverter the inverter is set to a max load and if it see this make load takes the load .. you may have lost battery power one day and every thing defaulted back in the inverter setting
all so having the inverter down line is that the inverter has no neutral to ground but the gen is if this is the case that needs to be looked at
you are all most like me but my setup is more HD my inverter runs all of the RV ac units and all
i was thinking your system would be setup like what i have .. when you said you like to dry camp
the other day i got a really upsetting email about michelle and all day you could tell in my posts i was upset and i am sorry for that .. i did not take as much time as i should to give the info i was trying to give
with your system it is harder to setup as you are trying to run a 220 gen and a 110 inverter .. when the inverter is in pass thogh mood every thing is cool but as soon as the inverter takes the load then the gen has only one side of the 220 working if the neutral is cut off when this happens power is lost on the gen side and this is where i think you would need a 3 input unit
if you look at the pic i made and what i said here you would under stand
look at the Y when it comes off the inverter
a open land ... power comes in for shore power......... power comess in
b closed gen .. no power
a closed land .. no power
b open gen ...............................................pow er comes in gen
a closed power from one side of inverter in .....power comes in inverter
b closed power from one side of inverter in .....power comes in inverter
this way your inverter gets power at all times but is not passing any in tell power is lost on the gen this well let you wire your loads right on each side of the 220
its sure nice to sure get every one saying your wrong but well not take the time like i did to show why and how it should be
alot of the RVs i worked on where higher end units with a RV fleet wood tech .. most of the RVs had 2 to 4 inverters installed like the outback units so they would have full 220AC even my inverter is setup to do this if i want
again to any one that would like to know just over a transfer switch shows two inputs (gen/shore) and one output. dos not mane it is not a 3 input unit .. look to see if it can see 3 inputs . look at the install files PDFs paper back . any info that comes with it
DOT standers for RVs says the inverter must be installed with a neutral to ground auto switch and in doing so well be installed on the 3input of a transfer switch or have its own transfer switch
