I'm upgrading my entire system. I've got 48 new cells coming, batrium BMS and going to probably replace my makeskyblue controllers. They're treating me well but I figure get some victron that can talk with the batrium.
I have 10kw in panels (probably add another 10kw)
1200ah @48v of lifepo4
Anyways. Debating upgrading my SCCs and going higher voltage.
I'm thinking either color or venus which basically just control the SCCs right? Batrium talks to it.
Then the part I'm confused on. The 250/100 controller. So its up to 250v or 100 amps going in to it whichever is more.
So if my panels are 250w 30voc I could throw 8 in series and be at 240v and if that's 2kw I'd only be looking at 8.3a
Now I've got 40 panels so could I do 5 sets of 8 in parallel?
Here's the part I'm lost on. That's 10kw (less in reality) but it's going to step down to 48v so that SCC would be pushing 208a out to the batteries. Is that the bottleneck?
Should I be running two controllers and 8s2p on each and I guess a 3rd that's 8s?
Maybe I'm thinking about something wrong here or should look at a different solution for the SCC. Maybe get bigger than 250/100. Or more smaller. I've got a decent run so rather not run a ton of wires but could.
Thanks!
