Aux port does not work in parallel and should be left unconnected.

If the inverter reaches the shutdown %, it should shut down the output and stop inverting. Once it reaches the restart %, it should start inverting again. Somehow it's not exactly working like that according to one of the previous posts?

Those aren't 3 pole, they are just the higher voltage version. The voltage should match what your inverter can handle. If the arrestor voltage is higher than your inverter, it will only start working after it's too late...

Option A, otherwise you require double the number of balancers.

Exactly like a grid-tie, yes.

This is from the UP2500 manual.

From the spec sheet - 17A

I'm not sure I fully understand your question? I agree with what he said, he pretty much just discusses the voltage limits. The Isc max was only recently added to the spec sheet. I can only speculate that SS maybe thought their safety margin was big enough (17A/13A) or software is sufficiently fast to catch overcurrent events and later learned that it is not necessarily true in all cases. And that is the reason he does not mention it there? (At the time of the video it was not part of the spec.)

The most amazing thing about them is the price!

Because you have an inductor and you work with current slopes. The software works in intervals - because that is the easy way to do it. So if you are too slow, and the slope too fast, you go over the limit of the active device before you know it. There is absolutely no way to get the voltage ratio here with a buck, without using exotic components and a way too big inductor. And then you still need a second stage. Most inverters do. It seems SS has finally updated their specs to include it.

No, there should be a max Isc rating, which you should not exceed, for the 5kW SunSynk, it is 17A.

It makes sense when you take into account that the first stage is not a buck converter, most likely a multi-phase boost, or more complicated converter like zeta, possibly even phase shift. (So you have active devices on the input side, that have a max current rating). The second think to consider is that it's probably completely under software control, which means current control is imperfect.

Actually it does not. It could estimate it, but then it would be making assumptions that don't hold in the real world - like when you introduce shadows and panels with cracked modules etc.

Perhaps an active balancer for the first week or two is warranted, after that if a small passive balancer cannot keep them in check, something else is wrong.

The Victron uses a Carlo Gavazzi ET112 instead of the CT (which takes more space than a CT)...

Well, you are in luck, because that is how fuses work.

From the hubble brochure: But at the price of the Hubble, there are better options that are LiFePo4, especially if you don't need a 1C battery.

The BMS alarm is actually configured for 155A continuous, and the trips set at 170A@1000ms and 180A@100ms.

It depends on the exact fuse, but if you want a 160A to reliably blow within 10ms, you need about 3kA... in 100ms that comes down to about 1.2kA.

You are thinking of Sahara, but Esquire is the place to go if you like having no aftersales support.

Then don't touch it! 🤪 230V±10% is the spec, so as long as it's not over 253V, it's still within spec.

Max is 800V on this inverter.

It looks like the string is split in 2 and connected in parallel to one MPPT. That would explain the flatline - the current is clipping.

Yes. IIRC, CAT 7 is always STP (and the whole cable also has a shield), so if you struggle to find STP CAT6, try CAT7.

Strictly speaking, at some point the capacitance of the twisted pair will become too much, so using 2 pairs will probably decrease the length by which you can extend. (and potentially confuse people into incorrectly using one pair per pole)
