Unable to decide MP-II 15kva vs. Quattro 15kva

Good morning everyone, I am doubting between the MP2 15kva and the Quatro or MP 15kva. The house is offgrid with 3*250/100 mppt and 1 fronius 8.2kw on the AC coupled side. 60kw lifepo4 battery. Also a generator.

I don't think I will ever need to parallel and the MP-2 would not be possible (but the normal MP would). Also on this forum I saw that in the future the MP2 larger units (8-10-15kva) will be able to

Internally, which of the two seems more robust? Will be charging an EV and supporting heating to the house (aerotermia) and a water pump (these are the big loads).

thanks

MP2 and MPII are the same thing? Or maybe you know something I don't know?

My mistake, I was referring to MP the older unit vs MP-2 (the "new ones")

Sorry I read 2 and II and got wires crossed.

FYI you can edit your post...fairly certain it was there in the OG post.

In any case irrelevant MP older unit does not have a 15kVa to my knowledge.

Thank you very much, I saw online that to parallel units, the units must be from the same badge (or year). If I order one unit and years later decided to take another, could be an issue?

In the other hand, also have a bit of preoccupation about availability of the older units if something happen.

Yes it can be an issue.

Even if you bought two at the same time and only added one years later as a parrallel unit. Electronic aging also becomes a factor on top of hardware revisions.

The older units still have plenty of application. Victron will make them as long as there is demand.

You can always split the DB anyway and have a separate system for those circuits.
