MidNite Solar MNROSIE7048M Mobile Inverter/Charger 7000W plus Victron MPPT

[Pr4mr22]

Doing some last minute research. I'm moments away from pulling the trigger on a Midnite Solar RV inverter for my 50A Class A RV build with a basement heat pump/AirCon, but I'm having trouble finding any reviews on the mobile version. For my purposes, I'd rather spend a little more and get the Rosie than have to wire up 2 Victron Inverters for simplicity and space saving. Anyone out there using the mobile version? Should I be concerned that I can't find reviews? Is there any real issues with communication/monitoring that I should be aware that can't be efficiently worked around? I am an Android user.

My intended base components for a 48v system -
MNRosie7048M
6 - 405W Sunpower Solar Panels (2s3p) (Approximately 91V at 33A) DATA PDF
Victron 150/45 MPPT
3 or 4 LifePo4 48v 100AH (Rack) Batteries
Thanks,
Pete

P.S. I may also reach out to MidNite Solar, but I'd like some feedback from real world users before contacting them.

I have the Rosie mobile version. Mostly because it was $2800 versus the RE model.

The difference is the M has an extra relay to handle the neutral ground bonding, if you were connecting to a campground or generator etc.

Mine doesn't have anything connected to the ac input, so the Rosie handles the bonding. The relay is unused.

But basically it's more capable than the RE unit, has ul 458 in addition to ul1741.

The other possible option is a little rosie, much lighter doesnt have the diecast aluminum chassis etc. Closer to 15 lbs versus 42. Basically half a rosie, 120V. Not quite as much extended surge as ut has way less heatsinking etc. What I haven't seen is how many can be stacked together, if you are calling maybe ask about that.

Either can work closed loop with the midnite 5 and 16kWh batteries.

And I have a variety of Victron sccs on the other side:

Thanks. This is the reason for sticking with the M. I will be occasionally hooking up to 50A/30A/15A, and I do have a generator in the RV for those times when I need a little extra juice because weather hasn't been cooperating. (Although less sun likely means less need for A/C, so hopefully that will even things out)

You can easily adjust the limit for ac input and it will assist with battery up to max power if desired.

I'll have to look more deeply into that thanks.

A couple of fairly recent videos from Ryan at MidNite Solar on Youtube about the Rosie that I found helpful although looking at the Rosie MNRosie7048RE for inside the home myself.

Probably a good idea to touch base with Ryan before purchase as will probably need some support after purchase.
Midnite Solar is known for good support, but documentation can be a little light sometimes as with most vendors.

Also Current Connected is a good vendor to purchase the Rosie and programing module MNGP2 that is required.
They are also known for good support.

Usually recommend to fuse between each row of panels when more than 2 parallel rows in array.

Midnite Solar also has a Forum

How will you mount the server rack batteries in the RV?

Keep in mind the vibration , moisture and crash containment that comes with mobile applications.

Might be worth looking at some of the new lithium golf cart batteries as they have provisions to be screwed down securely.

My 2 cents, the Midnite Rosie would be my top choice for a large RV.

Can you expand on this? I am familiar with the Victron PowerAssist feature. I want to install 2 Rosies in parallel in a 50 amp RV.

I would like to know what power I will be able to use from a 30 amp pedestal. Will it simply pass through or will it supplement with the inverters?

This is my only current concern about the Rosie. In all other aspects I prefer it to the Victron solution. At least so far!
