New Inverter and Wiring Question - Pluto - 03-28-2025

Good morning all

Our original Amana refrigerator has completely died on us.  After installing new evaporator and condenser fans it worked well for a month or so but has stopped all together now.

We have found a new refrigerator that will work for us and we are going to pick it up this weekend. 

On the thread for our refrigerator, there was mention that the original Heart Freedom 25 could have contributed to the death of our refrigerator, being that it's not a pure sine wave inverter.

My concern with a newer and probably much more sensitive electrical system on the new refrigerator is that the old inverter could possibly damage the new unit. 

Our plan is to replace the old inverter with a new pure sine wave inverter/charger from Victron (probably) ASAP to prevent any electrical damage on the new appliances.

My big question is in regards to wiring the new inverter/charger. 

The original inverter powers 3 twenty amp breakers in a small breaker box right next to it.  The box is fed by a roughly 2' section 10/3 cable from the inverter to a 30A receptacle that then feeds the breaker box, which seems simple enough.  I'm guessing that this is 240v feed, but I have not checked yet.

The thing that is confusing me is that there is an external Corcom EMI Filter that comes out of the inverter and feeds off to somewhere.   I'm not sure what the purpose of this EMI Filter is or where it feeds to.

Unfortunately I have not found any paperwork for the original inverter in the coach and we do not have any coach wiring diagrams like we had with our Foretravel. 

I'm sure a lot of people have replaced the old inverter and I'd be grateful for any advice.

I have posted pictures of the inverter layout and the EMI Filter that I'm talking about.

Thank you
Tyler Phillips

Yep!

Ditch it, I think it was Newell’s attempt to take some of the buzz out of the PSW inverters.

Thanks, Richard I was hoping that it could be removed. I'm going to NAZsolar in Flagstaff Monday to pick up the new Victron system.

Morning Tyler,
In the mean time, since you guys are on the pedestal, you could move the 30 amp panel plug from the inverter source over to the AC power receptacle.  That would allow you time to get the new inverter installed while using the new fridge, along with the other circuits, on shore power.

NAZsolar was recommended to me from a coworker, they had everything we needed in stock for cheaper than I found online. We went with a Victron Multiplus II 12/3000, Cerbo GX MK2 and GX touch screen.

Thanks, Steve I didn't know that! Hopefully I'll have it installed on Monday
