Power switchover problem?

We have a monaco 40, with a magnum modified sine wave 2000 watt inverter,auto transfer switch,50 amp smart energy management system,with 500 watts solar 6 new house batteries.
The problem i am having is the other day i discounted shore power for about 6 Hr ran off house batteries ,no problem.Turned shore power on keep hearing clicking but no power.Turned switch at pestle back off tried again same thing waited for transfer switch to kick in.On the 3Rd try it kicked in and we had 50 amp power an panel .,but now the frig(we have a samsung residential) upper part will only get to 48 % we are at -4% in freezer?Tried setting but no luck.
With this type of setup do i need to do anything when hooking to shore ,turn on gen,or running on house batteries,does the system know what system is on or do i need to do something?
Thanks for any advise

Your system sounds like it is is fine. The inverter is supplying power in the absence of power from the pedistal or the generator. The transfer switch controls the flow of A/C power (either pedistal or generator) to the coach. You should turn off the generator before you connect to shore power and also disconnect from shore power before you turn on the generator. If you don't, you can easily damage the transfer swtich.

The problem you had was caused by your transfer switch not transferring power back to the coach electrical system. Lots of potential reasons for this but if you want to try a few things yourself you can check the wiring inside the transfer switch for loose wires (do disconnect all sources of power before you try this). Many times there are loose power leads inside the transfer switch that just need to be tightened down. Loose connections mean heat and intermittent connections - just like the problem you were seeing. Also, if it happens again, give thhe transfer switch a good thump with your hand. That can free a stuck relay and get it working.

I don't know about your frig, however. Since the freezer is at -4, it is obviously cooling. The refrigerator section being at 48 doesn't sound right. I'd give Samsung a call and ask them what is wrong.

As far as needing anything, I suggest you have a Progressive Industries HW50C EMS system installed before the transfer switch. This will protect the coach from miswired pedistals, too low or too high voltage, open grounds, etc. Think of it as good protection for all of your electrical goodies.

Power switchover problem?

Could have had a voltage spike and damaged the electonics in your fridge. It sounds like it is working. Maybe unplug it (the fridge) for a few minutes and then plug it back in so it's processor can reboot. We had our house fridge get zapped when the power grid came back on after an outage. It was a blown fuse on the circuit board. I try to unplug shore power before starting generator. And, turn off the generator before plugging in the shore power.
