Your batteries are not providing 12vdc to the house. THey are disconnected or a fuse or breaker is tripped or they are toast.
>I missed a wire on the battery connection, that fix the DC issue
SOME RV's have an Energery Management system (Common in high end 50 amp units) this is designed to shed selected loads ICLUDING the A/C and Microwave when running on 30 amps and drawing too much current. THIS should hot affect outlets however.
I'm thinking there are circuit breakers on the inverter as well and they power the outlets and microwave
>I am plugged in to 50 amps power source. The problem is I have reset all breakers many time, and does not know if there is a fuse causing all this

First question is do you have a salesman switch? Second question is do you know where it is? Usually it's near the front door, but it depends on the mfg. This switch is designed as a convenience switch to turn off A/C power quickly without having to turn off the disconnect switch in the basement. Check to see if yours in on. Recheck the breaker on your inverter. On mine it's a really small push button and easy to miss. Yours may be different. Recheck all your wiring. It's easy to overlook the simplest things especially wiring. Be sure to let us know if you are successful in tracking down the gremlin...Dennis

1. Salesmen switch would have NO affect on the roof AC operation. BUT, IF the salesman switch is OFF, THAT would affect the operation of the roof AC controls(tstat). But it would not affect 120 to the AC
>Salesmen switch is one , DC problem is caused by a missing wire!
2. So, from the description, his battery disconnect is OFF. Find the switch and turn it on
3. Inverter/Chargers are NOT wired thru the battery disconnect switch. They are connected directly to the coach battery bank.
4. Yes, you should always disconnect 120 power when changing batteries, but I doubt that is the cause of your problem.
5. What is strange is you state you have interior dc lights that work. They should NOT work if the battery disconnect is OFF.
6. Also, you may have a EMS(120 energy management system) system that controls your AC units and the microwave and THAT requires 12 volt and 120 power to be ON. Doug
>DC is good even not plugged in to the power source, but AC ,outlets problem still not fixed...
PS, I would be a rich man if I had $100 for every customer that stated with 100% certainty that he had ALL battery cables connected correctly and did not miss a wire or connect it wrong when changing his batteries. When then come in I point it out and they were positive they did it right. If it worked correctly before YOU messed with it, the odds are it is something you did wrong
