My understanding is (I could be wrong and I will find it out on Friday) there should be already a 50amp wire from the transfer switch to the Magnum inverter, and from the inverter, there should be a 50amp wire goes to the main power panel, otherwise I wouldn't have to power with the current inverter but I do right now.

Jim Stringer Posted June 19 Share Posted June 19 Rick, There is only one 50amp wire that feeds the RV so theoretically he needs one from the transfer switch to the inverter and then from the inverter to the main breaker box. Link to comment Share on other sites More sharing options...

Look at the prints. IF I AM CORRECT....You have the DUAL IN and DUAL OUT Magnum system. There are TWO 30 Amp breakers (Download your manual from MonacoCoach....its all in there)... They FEED the SINGLE Magnum unit. The DUAL out then goes to the Sub Panel. That Subpanel is basically a 220 VAC panel...but you only use Line 1 and Line 2. Again the manual has the breakers. I KNOW for a fact that is how it works... IF you start to swap out inverters and such...then you will need to figure out HOW to use the existing wiring from the SINGLE inverter and get it back to the Subpanel. BTW, that is only #10 wire...not any #8. SO, there ain't NO 50 Amp lines there... LOOK BELOW...

That is A LOT of work, I hope I don't have to do this. If you do as proposed above, you will be bypassing the inverter completely (and if the inputs/output to the inverter are not removed, likely destroying the inverter). Or, are those Red boxes indicating the Victron Inverters. If so, you likely don't have sufficient wire capacity (50 Amp for each leg) going into the inverter. Secondly, if you simply wire the output the way you show, only the outlets that were on inverter power before will be on the new inverters. This will not power the whole Main Breaker Panel to allow for the A/C to operate, without additional wiring. -Rick N. 3 hours ago, JDCrow said: This is what I had to do.

It all depends how Monaco wired the inverter, they could wired the inverter as following 1) When connect to Shore power/generator running ==> Transfer Switch => 50AMPS =>Inverter => 50 AMPS to Main Breaker or 2) When not connected to Shore power/generator Not running==> Transfer Switch =0 AMPS> Inverter Generator Power from Battery=> Generator 30AMPS(or 20AMPS?) => 30 or 20 AMPS to Main Breaker In my opinion ,this is the most logic way to wire the inverter, If they wired this way as I am hoping I wouldn't need do much.

John - Please look at your wiring diagrams. The answer is there. Power goes from the transfer switch first to the main panel breaker box then via circuit breakers to the inverter input and then from the inverter output via back feed circuit breakers to the sub panel box.

OK, that will be much simpler for me, I can just hijack the two wire from transfer switch, wire those two hots to my two inverters, then combine the two inverter send the back to the main panel. then I just disconnect the Magnum inverter, of course wire the 12v connected to Magnum to the DC input of my 12V Victron Inverter, wire the 24v new wire to 24 Victron Inverter. I believe the transfer switch is in the same storage compartment as the inverter. Link to comment Share on other sites More sharing options...

Jim Stringer Posted June 19 Share Posted June 19 Thats exactly what I was trying to say....bypass the original inverter....I took my old one out and replaced it with an outlet. Or you could just put a junction box and tie the circuits together there. My new inverters supply both legs of the 50amp wire coming from the transfer switch to the main breaker in the rig.

This is a popular approach, and one I often recommend. But it does not put the entire coach electrical system on the inverter (i.e. A/Cs, electric water heater, etc, ) on the inverter. It only puts what was already on the inverter back on the inverter. I think the OP wants everything on the inverter. - Rick N Link to comment Share on other sites More sharing options...

Jim Stringer Posted June 20 Share Posted June 20 @waterskier_1no actually this puts the entire coach on both inverters. By removing the old inverter you are just completing the circuit to the few items that were originally set to run on inverter. The two inverters he plans to use will supply each leg going to the main breaker box just as if if was coming from shorepower or generator.

granvillebarker Posted June 20 Share Posted June 20 Jim, I don't think you understood what I was saying about your inverter battery wires. The existing ones run from the inverter to the rear run box, you can unhook them from the rrb and connect them to your 24v batteries and move the other end from the current inverter to your two new ones. No need to run new battery wires to the inverter. That cabinet you proposing to put your 24v batteries in is right above your muffler, I think. You may want to evaluate the heat in there before using it for batteries. -- Granville Barker Link to comment Share on other sites More sharing options...

Jim Stringer Posted June 20 Share Posted June 20 @John CI made brackets from aluminum angle and then used industrial double sided tape the front two panels are secured to the angle brackets which are taped down and also screwed to the roof....that the only point i used screws i then sealed with sealer and then i used flexseal tape along the front to help seal against air and water so its like a ramp for air....the rest of the panels are screwed to each other and i have brackets coming down to attach to the aluminum angle that is taped to roof....all the panels are pitched slightly for water run off....the panels are about 1.5" above my ac covers....I have put about 3000 miles with this setup so far it works....lol...probably not everyone elses ideal install but at the time I was on a budget....

waterskier_1 Posted June 20 Share Posted June 20 13 hours ago, Jim Stringer said: I hope this diagram explains everything better I have never seen a coach wired this way. No Monaco' came from the factory with the Inverter Output wired back to the Main Power Panel. The output was either wired to a microwave and a string of outlets (lower level coaches - Knight, Dip, etc.) or the output of the inverter fed an Inverter Sub-Panel (higher end coaches - Dynasty, Exec, Sig, etc.). Your drawing does not simply "bypass the inverter". It also requires new 50 Amp 6/3 with ground be wired from the transfer switch to the inverter(s) and then another run of 50 Amp 6/3 with ground be wired from the inverter output back to the Main Power Panel. I have designed coaches with a similar approach, but it does require rewiring the coach. Firstly, the wiring described above, and then wiring the old circuits that came off the now removed "bypassed" inverter back to a circuit breaker (the previous one was in the inverter) and picking up power from the Main Power Panel (the existing wiring from the Main Power Panel to the inverter can sometimes be reused to input a new mini-circuit breaker panel (box) that would then feed the microwave and outlets previously fed by the old inverter). -Rick N.

Jim Stringer Posted June 20 Share Posted June 20 @waterskier_1I am sure you seem to have alot of experience in this....but I know how my coach was wired and thats how I showed. If my inverter was not on my microwave and a couple other items would not power on regardless if the coach had power i.e. generator or shore power. attached is a picture of my main breaker box which has a circuit that was fed from the inverter.
