Trying to complete an upgrade for my parents setup. I put most of it in about 10 years ago, and recently I about quadrupled the PV for them but now need to upgrade the solar charge controller from Midnite Classic 250 to a charge controller(s) at higher voltages.
My constraint, other than money of course, is the physical space is very limited, and so while looking at adding 2-3 new SCC I started thinking about perhaps it would be better to switch the inverter to an All-In-One so I could take advantage of the space savings.
The current inverter is a Magnum Energy MS4448PAE which has worked flawlessly for years. The mark of something great is when we've never even thought about it, so I'm a bit hesitant that the EG4 12000XP might bring unforeseen problems.

The other issue, is the confined space. Both sides have windows, so there is OK air flow, but it's much tighter than the recommended gaps on the right.
So the cons:
1. If it's not broke, don't fix it for the MS4448PAE
2. Overly tight space on the right of the future EG4 12000XP. That side has the fans, left side has the filters (which I think is the intake?).
Pros:
1. Bigger inverter for more power. I'd love for them to have at least a bit of AC for hot days which seem more numerous lately.
2. 12000XP has two MPPT with high amps ~44a input for each so no need for external solar charge controller.
The mess of wires on the top is the AC -> 12V DC for pump/lights etc.
What are your thoughts? Anything I'm missing?
