I am considering getting this inverter, what is the max amp output listed on your solar panels? The panels Im looking at are about 13.5 amps each and I would like to parallel them but since the max draw is 22 amps I would lose a fair bit in ideal conditions. I also wonder if over paneling it would reduce the lifespan, my idea was 6840 watts per mppt input. You mentioned adding more inverters, Im curious how you do this without paralleling them? I dont really undertand how I could expand on this system other than running seperate electrical panels for each AIO. Makes me wonder if I should get a couple 6000xp instead for ease of expansion but the cost would be practically double.

I can’t speak to his full array but at least a portion is the NE 370s which are ISC 11.33 IMP 10.74
I don’t want to speak on @42OhmsPA behalf. But we have also chatted about this in DM as to if some of the output caps he’s seen are in regards to his parallel strings being slightly above the MPPT limit. If I’m not mistaken he was running 7s2p and I was hoping to run 8s2p on mine which is what prompted said discussion.
One note on the 6000xp is you won’t benefit at all from parallel strings as the input amps are much lower

ya i realise I wouldnt be able to parralel with a 6000xp for sure so double the wire. But I could add more panels without being clipped.

I would wait until SRNE releases the 10Kw version that can be put in parallel. It should be released soon. If you plan on expansion or need the inverter capacity, that may require parallel units.
SRNE informed me it is coming soon.
This will also increase the number of MPPT's so no need to parallel strings.

You can use the SRNE 5kw versions, those can be in parallel.

This was initially my plan but when I emailed SRNE asking about a larger capacity parallel inverter they didnt respond. I will need to be setting up my system this summer so I need something by then. The HYP versions people mention on here that are stackable I cant seem to find at a canadian supplier. I dont really want to deal with ali express since if I have problems with the product I'm probably on my own.

Right now you won't get too many answers from SRNE due to the Chinese holiday.
I would buy on Alibaba from the SRNE store but not Ali Express.

No, my point was that the 6000xp allows even less solar input both in watts as well as amps. I believe each input on those is rated for something like 17a. The voltage limit is close enough or possibly the same that while you may potentially gain one panel in series, you’d lose an entire parallel string per input

No because I am comparing buying two 6000xp to one ASF 10k. The max watts for pv input for the SRNE is 11000 and the max watts for two 6000xp is 16000. The amp limitation means paralleling panels is not logical but the amount of panels i can connect or at least the watts I can get out of them is higher with the 6000xp. Voltage limitations are identical and idle consumption is the same. My reason for wanting the SRNE though is the cost of one 6000xp is pretty much the same as the SRNE, plus if i parallel panels I save on wire.

I have them wired 7s2p on MPPT1
Yes you would.
If they are angled appropriately you will lose out on a fair amount in ideal conditions
That's exactly what I would do if I go with another ASF.
Personally I wouldn't based on my SRNE experience. Iirc the 6000xp has a lower current rating per mppt than the SRNE.
You could aim your arrays different directions and parallel them, that's how I have MPPT2 set up. 9s2p 315W Q Cells aimed S and W.

I got you now. That makes more sense with 2.

You mentioned having significant gains in winter simply by adding a very small amount of panels and a victron. What is it about the victron that is giving such a benefit that the SRNE isnt providing?
42OhmsPA

I may have worded that poorly.
The Victron starts producing power sooner and stops later than the SRNE but the power isn't really useable.
The significant gains came from aiming the small victron array SW at a steep angle, much better than my shallow angled W facing roof array.
In the winter every little bit helps.

If I do go with this inverter and do something like 6s2p or 5s2p if the panels have a voc of 50 volts and an isc of 13 amps what happens in the summer? My understanding is that in the summer the heat causes voltage drop of 0.4% per degree but your watts dont usually drop because the amp increases pretty much proportionally. If I have reduced the amps to 22 by paralleling and my voltage drops due to heat will I see significant drop in summer watts? Since summer production is great anyeay should I even care? Would running at max amp draw for the mppt be potentionally risky for the equipement?

Mines clipped at 22A for kWhs and kWhs of production since installing the panels on the ground mount late last year.
