Isn't this the same one that has already been discussed on the forum and reviewed?

Yes but that one is a 60+ page rambling around. I can see the value of this dedicated thread now it's been officially released.

Good point, having something dedicated is good, thanks @InTheHills. For a second I thought there was an updated MidNite model out already.
 
@InTheHills Thanks for the new thread - it's definitely become impossible to read through the original one.

Questions:
1 - The brochure states "Up to 200% oversizing allowed with 3MPPTs" but also says "15,000W Max PV input".
So, can it be oversized to 22,800W?
If it accepts 15,000W and has 11400W continuous power with PV, what happens to the rest of the 3600W?
Can that be exported to the grid or charge batteries?

2 - Max input current per MPPT states "30A/22A/22A", but does any one MPPT have a Max?
If the 1st MPPT had 10000W in and the 2nd 5000W and the 3rd unused would that theoretically work?

3 - 200 amp vs. 100 amp Inverter pass through. I've read through the article by Robin and appreciate the explanation, but in a Parallel system it states 2 inverters Grid “Pass Through” 200A but the wiring diagram for 2 inverters on page 52 doesn't show how they suggest loads be connected.
How would one configure 2 inverters to Pass through 200A.

4 - There's been a lot said about the various loads, smart loads and added breakers but I wish there were a few examples of how these could be used (potentially some example wiring diagrams)

The inverter will self-limit what can come in. It would be unwise to do this in the sense that it would be a waste of half your solar array, however, the inverter can handle it. If you have 22.8kW of solar, a second inverter would be a wise investment.

Battery charging. If batteries are full, generation will be tapered back to 11.4kW.

Yes, however, if the 30A rating is exceeded power would be clipped, so the operating voltage must be high enough on that MPPT to reach the power level without exceeding the current rating.

In parallel - grid terminals would get joined, load terminals joined. You could use either two breakers, one for each inverter, using the electrical panel's bus bars to make the parallel connections, or you could use Polaris splices or other means to join the cables together. Smart load ports can operate independently on each inverter, no need to parallel those.

The ports can be used for generator, AC coupled solar, and/or (meaning the generator and AC coupled ports can be used for other things if you desire) loads that you want to turn on/off at certain charge levels. The wiring is quite simple, run wires from the breakers in the inverter straight to the load you are trying to power. The diagram would literally show two wires going straight from the breaker to the load...

Thank you - that's a great reply.
Definitely interested a Parallel set of 2 and that helps in clarifying.
 
So I was discussing MidNite ONE on someone's build planning thread. And I found some unique capability that hasn't been discussed yet.

The MidNite One only has 100A bypass, but it has something approaching 200A of load/backfeed breakers on its internal bus.

I can sort of imagine that you can actually serve 150A worth of loads from it! Imagine using the 60A Gen breaker to feed a 60A subpanel, and the 100A output breaker to feed a 100A subpanel.

Contrast this with 18kpv and SolArk 15K which do not have multiple output breakers. So if those breakers are hanging off a >200A internal busbar, it might be possible to go >100A. In fact there are something like 200A worth of output breakers on this inverter! Between the non-relay controlled load breakers, 3x smart breakers, and the AC output breaker.

I think it is quite conceivable that you can do the 100A + ~10kW-AC of the inverter! It most likely will be admitted by the OCPD without tripping. Whether this is allowed in the sense of being safe for the busbar, I don't know.

@HighTechLab Since you have the inverter in-hand, do you know if this is a legit way of thinking about the inverter's capability? It would somewhat help to narrow the gap with the 15K in total amount of supported loads when on-grid.

looks like a perfect one for me
trust their quality 100% ( 150 classic running full load for 5 year now )
but @ 5k plus, very tough
around 4k is nice
 
This was answered in the other thread (now gone) so figured I'd ask it again -

What battery protocols does the MNAIO support?

This is the old EG4 no suffix. Not the EG4 LL or LL-S. AFAIK you can't change their protocol.

Yeah the originals you couldn’t change anything. I believe that’s why the developed the Communication Hub though. You would want to double check to see what all protocols it supports.
