Bit of an update...
Any of you guys have an old man that is difficult to deal with?
So I did the math on the amperage that will be coming from the panels and it should never exceed 18.6 amps. I asked the old timer if he was sure that 14/2 couldn't handle that amperage. He went on about how code has changed and he thinks that it should work, especially because it's buried underground. I say great, then we can move everything up top and use the old Kubota 7.5kw genset that is already up there and also has a 2 wire remote start already hooked up to it. He says "I like that idea, lets use what we have" I then get a text half way through the week that says "I think we need to bite the bullet and bury a new cable cause 14/2 won't cut it" I say no, we'll just use the new generator that I bought and stick with the original plan. He became insistent that we do it this way because if we don't that old generator will just be sitting there doing nothing and he wants to save some money. This is my money that he's talking about, btw and I couldn't give a shit about a 1200 dollar generator. I bought a 4500 dollar dock last week. But, you are always going to be your fathers child and he still thinks I'm 18 and hurting for cash, I'm 45 BTW. So it goes without saying that I had to bury a new 10/2 all the way from the old generator shack, down to the bunkie, digging most by hand and only using a trencher through the driveway because I ran out of steam. Then, he goes on a 2 week long golf holiday and I'm stuck doing this by myself. The real kicker is that the lv6548 might not even like the power coming from this old bastard and I may have to install the new one in there anyway, which would put me right back to where I was before I ran this new cable.

In between the 2 boat houses.

Other side of the second boat house. Had to go under the mother of all roots here.

Up to the front corner of the cabin. I had originally planned on running it up the cabin and along the side of it, but then I got bury cable and not tech, so in the ground it went.

Up the hill to the driveway.

Across the driveway, used a trencher here.

Up to the water tower, more roots to go under.

Into the generator shack where the batteries and brain are installed now.

Grossly overestimated how much cable I would need...
I've installed a splitter on the generator stand and all that it left is hook ups. All the had work is done. My one question is whether or not it is okay to use a standard cat6 patch cable for BMS communication with the batteries and the lv6548, or is there some special wizardry going on with those cables? I have cables and ends and the tool to make my own if there is some kind of specific way that it needs to be pinned and someone has a diagram kicking around...
I've also removed the ground neutral bond in the inverter itself and will be doing that in both my panels which are both main panels as they are separately run from the splitter and not off each other.
Thanks for following along this journey with me and I'm almost done I hope.
