We want to exchange out existing modified inverter/charger to a pure sine wave so we can run a residential refrigerator. We have solar panels. What is everyone going to?

I installed a Samsung RF18 which works with a MSW so I did not exchange my inverter.

There are a number of newer refrigerators. The ones that have an Inverter motor on it they will usually work with MSW inverter.

You might opt to install a smaller dedicated PSW just for the refrigerator. I actually installed a second PSW inverter to have as a backup. Since I had two circuits going to behind the refrigerator I took the one that was not on an inverter and rewired to be able to use it on inverter if I want.

Agree with above. Can't see coach what you have in phone app. But if I was to spend $1000-1200 on. PSW I would spend extra to get a3000watt Victron Multiplus 2 for the 50 amp passthrough. But I boondock and use inverter genny a lot. It can hybrid boost what ever power you set it at off batts.

When I installed a residential fridge in my old Beaver, I installed a dedicated 1000 watt pure sine wave inverter and transfer switch just for the fridge. It was much cheaper than upgrading the original inverter. The system has worked flawlessly for the last 6 years.

To respond to your original question, my first diesel pusher had a Heart inverter. When it died I replaced it with a Xantrex since Heart had been bought up by Xantrex. I was not happy with the quality of the Xantrex. My current motorhome has a Magnum. It has functioned flawlessly for the 6 years I have owned it. It has the Magnum automatic generator start and battery monitor system (optional features). All seem to be quality products. I have heard many good things about Victron products, but I have had no personal experience with them.

FYI Amazon has the Renogy 1000 watt pure sine wave inverter for $168 and the Xantrex automatic 15 amp transfer switch for $68. If I were doing it today, that is probably the way I would go. OR, if you have not purchased the fridge yet, look at the 12 volt DC powered fridges and avoid the double loss of converting from DC to AC and back to DC. Much more efficient.

Before you spend any $, really take a look at the Victron MultiPlus 2. (50 amp coaches or MultiPlus 1 for 30 amp coaches) Compared to the original equipment I had in this coach, it's really impressive. besides being a hybrid inverter/charger, It can work with solar, and all types of batteries. It has more abilities that I could mention here.

I see 153stars touched on it above.

I ended up with an AIMS 3000 pure sine due to supply chain issues - and I've been pleased but kinda wish I waited for the Victron or Magnum. The remote is hardwired on the AIMS (seems like they should all have a wireless option) and I still have yet to snake that Ethernet cable up into the coach. The pass through feature alone on the Victron make it attractive. Also, I will never, ever own another Xantrex device. Every one I have ever owned or inherited has failed. Also #2 I am unclear on the residential fridge thing. I have a 2004 Norcold that runs 3 ways and have yet to burst into flames. As a boondocker I appreciate the flexibility.

On my 2000 Dynasty. I installed the Multiplus 3000 (this is before the Multiplus II came out) - I love it!

That’s about the only thing I would change is getting the II (and getting the Cerbo - instead of the CCGX - also not out when I installed it).

If getting a residential fridge , you will probably want to add some solar. I originally added 800w (four 200w panels) and a Victron mppt 100/50 with a new wire run. Later when I added the residential fridge (Fisher and Paykel), I replaced the 80w original solar panel with two 210w panels and replaced the original solar charge controller with a Victron 100/30 - used the original wires.
