Will the "Beginner Friendly All-in-One Solar Power System" trickle charge a Tesla? Help!

I purchased an Iron Forge Cable 3 Foot Lighted Outdoor Extension Cord - 10/3 SJTW and hooked it to the AC output on my Growatt 3000 24v inverter.

The colors to set up the Ground | L | N for the Iron Forge extension cord isn't clear to me.
Based on the photos, do I have this set-up correctly?

Unless they look different not on a phone the conductors appear correct

But there’s too much bare wire exposed from the terminals for my liking.

GREEN is GROUND

Fixed!

I've purchased two more 12v 100ah AGM batteries.
Are the diagrams below correct to set up four in 2S2P for my 24v inverter?

Thanks! And now the newbie question: I have three black & red 2 AWG wires.
I can see the red cable from my inverter would go to the bottom left 12v battery and the black cable would go to the bottom right battery. What about the other ones? Do I use red or black, and if so which one?

Sorry if I'm not clear, but I was wondering (question) whether it matters which red or black wire I use in the diagram above.

The schematic you posted is fine. The color of the cables does not matter, the most important thing is to choose the right section (awg). You can wire all black and put a red wire between the + battery and the + AIO inverter.

My current set-up has my inverter (Growatt 3000 24v) connected to my two 12v 100ah AGM batteries.
My issue with the Growatt is that it drains my batteries overnight, even in "power save" mode.
So, I think it may be best to have a battery disconnect switch between the inverter and the batteries. Also, it would be helpful in case I need to work on the inverter without power coming in from the batteries.

Any suggestions on what I should use? Hopefully, I am explaining it correctly.

I don't advise you to use a switch to disconnect your batteries every night. A 3000W inverter should be pre-charged before connecting the battery, see Will's video below. On the other hand you can use the off button of your inverter, this does not disconnect the battery and should consume nothing.

Edit: oh yes you have AGM batteries so it's less important. With Lifepo4 batteries, without pre-charge it is possible to damage the BMS of the battery which can see the current draw as a short circuit and destroy its MOSFETs in the worst case. You can also damage the terminals of your batteries during the connection.

"

Sorry for the newb question, but do you mean simply a red wire should run from the inverter into one of the batteries (as shown in the photo)? The same would be said for the black from the inverter to the battery bank.

I would use a red where red, black where highlighter black, and use tape on the ends of the series cables red and black accordingly. If it were me

My red circles: is that one red or black wire?

 

[Sleeper85]

As already said the color of the cables that you have circled in red do not matter. If you take a red, put black tape (or thermo sheath) on the - side. If you take a black put red tape (or thermo sheath) on the + side.

Look on the photo below, the + cable is black with red tips.

One cable regardless of color. Marking the ends with colored heat-shrink if you make the cables or using quality electrical tape is perfectly acceptable. If you have a bunch of black cable as others stated: marking the terminal ends is fine.

I would be ok with all black cables but I’d never use red for a neg(-) connection, and probably 100% would make up your circled series cables from black.

Electrically it doesn’t matter but for safety and ease of service purposes that’s what I’d do.

Thanks! I'm just concerned about fucking it all up that I was overthinking it. I appreciate your kind response.
