Growatt spf 3000tl lvm-24p

[Chefjjdecker]

Wiring this baby up...please, I need your help. I've read through the manual and watched videos over and over.
It can handle 2,000 watts PV at max 145 voc with an 80a mppt.

Okay so I also have the overkill solar (8awg wires)100a/8s BMS wired 2p8s from 16/190ah cells. So another question. The BMS can handle 2400 watts but the inverter is 3000? What would be a safe constant load?

I need better instruction regarding the fuses and disconnects. Can the 8awg bms negative connect directly to the DC input? It's 2 feet long. And add another from battery positive to Growatt?

Instructions for battery connections say to use (1*2awg). Same box underneath says (2*6awg). Confused.

PV connection says 80amp 6awg. I'll be using 6 of the bouge rv mono 180 panels in a single series. Each is 22.5 voc and 8.91 amps so that would be 135v at 8.91 amps.

Hopefully, I'm on the right track.

So was going to use 8/2 electrical wire into the main breaker (40amp fuse). Does that mean I use 8awg into a sub panel also?

Guide me a bit. I have 150amp fuse, 2 100amp buss bars and the panels on the way.

What am I missing at this point? What would you do differently? This is my first build. Thanks. chefjjdecker@gmail.com

Hi. Just wondering how your build is progressing. I'm thinking about going with the Growatt for a similar build and I'm trying to sort out the BMS side of things. Thanks

I'm returning my $1/watt Bouge RV Panels (180w)
I purchased santan solar 250w snail trail panels for CHEAP. I got 10 panels for 600 delivered to NC from AZ
I got it on a dolly in my RV. I also bought 2 of the 120amp 4s bms from overkill solar for my other batteries I have coming.
The first came with a coozie and nuts and the most recent order came with 2 coozies. Was a nice gesture from overkill.
