Use for solar setup

I have 18 x 12s modules and 4 x 6s modules.

That would be 22 total, correct?
Then yes, 3 more.

Yes that’s correct. Thanks.

I have the 19 done. Parts will be here today.
Should I send the 19 first?

If you can so i can get started. Thanks

I have the other 3 done if you want them. Can’t go out until Monday.

I put the double 6s in boxes.
After connecting two 6s in series, one will be low and one hi.

MVC-005F

19 are paid correct?

Thank you. Yes. The 19 are paid. Paying for the 3 now.

Tnx,
Will go out tomorrow.

Hello Dave,

I’ve received the parts. It looks amazing. I know i cant solder like that. I see that you have those male connectors on the board. What are they called? I would like to get some of those.

I’ll get you a link.

Thank very much. I will probably do this

Wires are not that hard to solder. Just stick through the hole and solder. Trim any extra.

Do I solder the B+ B- and T also?

T is not used. It’s the sensor lead.
I do B+ and B- even though the power cables make the same connection.

Hello Dave. Just wanted to give you an update. Here’s my soldering job. Not the best but works I hope. So about about to solder the 6s pack boards. When plug in the wiring. Where do I plug in the “6” cable since they are connected from board to board. I’ve posted the pic.

The two boards for the 6s are marked high and low.
Low outputs 1-6 and high 7-12.
After plugging them into the 6s modules, test voltages as you parallel the 6s to the 12s.
I have them marked, but that depends on them being connected to the correct module. High or low.
