I think we are at the point now! Its not an ,,accident,, I'm asking this. I built everything very carefully. I have multiple layers of fuses, bigger diameter cables, 3x checking every voltage, polarity, and so on.... I don't want to try anything that can leading to demage. The thing I'm. really...

Oh! Hope not. I have no problem with joking, but now here for real experience. I don't want to try any setup that have any chance to demage my equipment.

Yea that's clear. But when will the SCC reach this status? When will it short circuits the PV input? Isn't it only about the reverse polarity protection?

Thanks but something isn't clear. That number is an example. The essential: What if I have a huuuge solar array what never exceeds 80V (not Vmp, not Voc), not ever reach the 100V limit. But the array is capeable of pushing 100A current. So if I'm righ te SCC only DRAW as much power as it need...

First, thank you for all replies! Sorry guys but I still see some contradiction. I'm not a professor so please forgive me if I miss something, but... 1. I = U / R. So if the huge 15kW array is fix 80V the current will change by the resistance. In simple: like the grid 230V AC output in your...

Why so?

Sounds pretty nice. And your paralell string capeable of 85Amp max? Wow. Your SCC never had any problem with that huge overshooting on max Isc? Does your growatt ever pull the max power it is capeable of? Did you ecperienc any warnings, errors because of the higher PV array Isc?

Thanks Tim! Can You please write a short info about your setup? Panels configuration, SCC, battery bank...

Hello guys! Please help me clear this! (if it's already discussed, SORRY for repeat) Some intro: I have a PowMr 5.5kW off grid SCC+inverter (yea know it's not the top quality stuff on the market). I have 9x385W (3465W) mono panels connected to it. I have a 100Ah 51,2V LifePo4 battery. I'm...
