Electric only working on Side 2 of inverter. FIXED!!!!

[rocmoc]

Same problem after installing a new inverter. Both sides of electrical works on pass-thu mode when hooked up to shore power. Switch over to invert and only side 2 works. This was the problem before installing a new inverter. Thought the old inverter was the problem as there was corrosion all thu the old inverter's boards & the electrical connections. The old inverter was tested at a local RV repair location and was told it was shot. I purchased a new (updated model) inverter (not from the repair location) and still have the same problem. HELP! Any ideas. Everything is great when hooked up to shore power but only side 2, Micro-wave & bathroom, works when not on shore power. Every outlet use to work!

Thanks,

BTW One of my Magnum outputs powers the MW. The second a GFI with an incredible 18 plugs (not a typo) plugs on that circuit. While it works on low usage plugs it is to me a questionable design. While I like my Monaco HR there are several areas that need improvement. Oops forgot they went bankrupt.

rocmon,

Since you have a HR I'll guess that you have a Magnum inverter/charger. If not how about more information?

The typical HR Magnum has a 30A AC input and 2 20A outputs - I know you said one was 15A??? Since you have AC input and AC output on one circuit that leaves:
1. A tripped CB on the failing output.
2. A miswired wire on the failing output.
3. The failing output is shorted and you can't reset it's CB.
4. The failing output is good and the problem is downstream as in loose wire or tripped/bad GFI.
5. Bad inverter/charger.

To me the testing procedure could be obvious but would like to know what equipment you have.

Took awhile using clever deduction.

How does this sound?

The INverter is wired so that it can feed only so much coach. Plug it in to shore power and you can have Yankee Stadium grade power. Disconnect and let the INverter do the power and they the manufacturer DO NOT WANT TO TRY AND POWER THE ENTIRE COACH.

Removed the GFI and by-passed. Problem remains. Getting to late to reroute output 2 supply to leg 1 to check the breaker on the inverter. Tomorrow! Sure wish they supplied the 120v wiring diagram for the coaches.

I suspect If he is feeding the 50A plug with a 30A source he has to use the standard adapter that has the 50A side LEG1 strapped to LEG2 like this DMBRUSS drawing. Without the strap he is only feeding one side of the 50A system




who knows how he is setup - need more info

NO! When plugged into shore power NO PROBLEM!!!!!!! (as I stated earlier) The problem is when using the inverter/converter to supply 120 to the coach from the 12V supply.

Aha!

It's a CON-verter

Not an IN-verter

How to ask this so that 200 words are not needed in the question?

[rocmoc]

Could a GFI outlet work in pass-thu mode and shut the leg down in inverter mode if the GFI outlet is failing? Could the sine wave inverter be that sensitive?

I'm a little behind on my 50a knowledge, but I do know it's two legs. So.. is that inverter designed for 2-120vac outputs? I've never seen a "50a" inverter.

I realize that it's probably not worth speculating, but my MH had its inverter wired through a subpanel with two breakers. One of the breakers handled the microwave and an outlet or two and the other had everything else. If that second breaker tripped the effect would have been as the OP described it, but it wouldn't explain why everything works in pass-through mode.

I'm as puzzled as everyone else; maybe the OP can provide more info.

Yup have a second breaker panel but everything is working. Will check a third time just in case.

Just checked, everything is good. Breaker panel is setup with a 50amp breaker that is marked Main (shuts everything down) and a 30amp breaker feeding the inverter. Everything else is fed thu the inverter except the frig, AC & washer/Dyer which are fed from the breaker panel.

There are two output sides, side 1 which is 20amp and side 2 that is 15amp. One in and Two out. Standard Holiday Rambler factory installation. I will check the output with a voltmeter tomorrow if I can find someone that has one. OR I will just switch the wiring between side 1 & 2. See what happens.

[time2roll]

What are you using for a transfer switch? Is the inverter connected to both sides? Have you checked voltage going to both sides?

Side 1? Side 2?

Does this mean INCOMING 120vac shore power...

And Side 2...

Outgoing shore power OR inverter power?


Honorable Chinee ahead getting themself. Putting horse behind cart. Build device, Sell device. Then find out instructions are Number 10

Take some images and post or find a link to the manufacturer that has the photo interpretation of "Side 1 / Side 2"
