Very new to solar but started purchasing items, not sure of the final specs of the whole system.
- Thread starter kromc5
- Start date
There were a few figures; everything was turned on after 10 am.
Victron 5s3p did 47.51kwh
Two 18KPV's with: 1 6s2p, 4 - 6s did 67.4kwh
Total Usage was 73.5kwh.
Since it's the first day of sun, I wonder how well this is after moving so much off the growatts?
It will be fascinating to see what is produced when I get everything moved over.
Batteries almost made it to 100 percent as well.

I assume your 450/200 fans turned on at some point, on my 450/100 it seems to turn on one fan at around 1000W, 2nd fan around 1500-2000W. Not objectionable at all.
They ran most of the day; it stayed between 5400 and the highest, 6051w. I could not hear it all over the growatts running.
I spent most of the day on wiring outside and then after dark removed the last of the growatts and mounted the second victron.
The cerbo immediately detected it, and the firmware updates quickly and easily. I like that it can scan all the devices
and update from one interface.

Tie bars of different voltage close together, and flat conductor could bridge.
Have any particular protection? Probably a plastic lid?
How about a rectangular plastic strip down the middle, standing taller than the busbars?

I discussed wrapping those in a previous post since the two-hole adapters put them closer together than the older style. Here's the delta between the old and new, showing their differences. I will work on addressing that today.
I also wanted to add the busbars are the same length between the two pictures.

I spent the day working on changing arrays and cleaning up lots of wire that was no longer needed. I removed midnite combiner boxes that were not required since I needed 4- 6s. I spent the evening working on the two victrons and mounting the 3rd. I finished the harness and got the second BMS online, and the battery is almost complete.

Three your final count for the 450/200s?
I'm unsure; I wanted 30 panels on each one. The math is 48.7 * 10.14 * 15 = 7407.27, which I would divide between two inputs.
That would be 30.51 amps, with the two inputs having 36 amps on the victron.
I got the 3rd victron online and converted the last two arrays into 6s2p. Using one of those on the Victron to charge the new
banks. Next, I need to convert two arrays to 5s3p and build two more 5s3p or 6s3p / 6s2p. I need to measure again but I might be able to fit panels vertically in rows of six.

Up to twelve 100W panels on the second string now, very impressed with the 450/100s performance. Seems to produce a little more than my 150/35s (within their limits).

Ok so you are under panelling a fair bit then.
