My husband wants to run 6 and 6 into our combiner box. Will this be okay? He had it started it out at 4 sets of 3, but that didn't seem to do much ? ??
He has 6, and 3 & 3 now.

Hi Will. My goal is just to off grid a couple of circuits.
I found a local source for used 335W 40x80 panels at a what may be a good deal. I'm not affiliated with the supplier and I just found them on CL. Please let me know what you think and it might be good to share with others as they have over 5000 in stock.

Issues with Growatt and Battle Born.
(2) Growatt 48V SPF 3000TL LVM
New 05 US2 battery setting locks User Defined Bulk and Float to same value.
But major issue is that Growatt inverters will NOT allow charge voltage over 53.8v !
Cannot use full (8) Battle Born battery potential.

Growatt response see attached
I hope Will can address this in the near future.

I have a Bluetti AC 200p in my house connected to 790 watts of panels. Is it safe keeping the panels connected all the time or should i disconnect them when not in use or not home.

Hello Will, just in case you might need a change of pace, I have been watching eBay for machine tools. When I saw a few machines in Nevada, I got to thinking that you live near that neck of the woods. See item 402911062233 , which should be a used Tormach cnc mill, https://www.ebay.com/itm/402911062233

Hi Will, We have been watching you for quite a while now and we are very impressed. We have a RENOGY DC DC 60 Amp charger we installed in January of this year. The DC DC does not appear to be working. We have a battery bank of 6 x 120ah LifePo4 batteries. The manual is confusing as far as settings go for lithium batteries. S5 is definitely off, what about the rest?
Regards Sybil and John

I am planning on building a 24 volt system to back up home and run small portable ac unit. I have 6 100w 12v panels( plan to buy more as needed). I will take the 2 BB batteries out of my RV for storage.
Plan on expanding system as money allows. Should I purchase all in one or separate components? 8000 BTU ac unit.
Thanks for any comments.
Built my 12 RV system using Will’s book.

Easy newbie question, I hope. Can a split phase inverter, like the 48V, 5kw split phase Growatt supply both 240 VAC and 120VAC simultaneously? The wiring diagram seem to indicate that it can. Is this true? Thanks.

Will, when cutting open these premade battery cases a plexi cutter might work better.

your video:

tool for ref: https://www.amazon.com/OLFA-1090486-Plastic-Laminate-Scorer/dp/B003UHUZ5U
I can send you one to try out. on flat straight lines it will cut through 1/4" plastic (any type) after two or three strokes. PM me

Can you please do a Growatt auto transfer video? I'd love to see your growatt set up in the trailer automatically switch the output from battery to grid when the battery/PV gets to a low threshold. I "think" that's a feature of the Growatt. This would go for David Poz with his 240 parallel Growatt setup. I don't think he's on this forum though.

Huge fan of you both.

Thanks,
-Scoleri

Off-Grid air conditioner/de-humidifier

I just received my fan motor. All it says on the housing is 12V.
I want to test it with a car battery. After I see that everything works as hoped
I plan to use 64 - 18650 Li Ion.
For the test do I need to install a resistor, potentiometer, rheostat... or?
Can I just run the leads to the battery?
I'll try to include a photo of the fan.
Any ideas?

Has anyone tried or tested the Expion Batteries yet? They have a 13 year warranty. Just curious.

I watch all your videos (over and over) on the treadmill. I may be mistaken but I've never seen you talk about compression. I see people on here talking about compressing their batteries all the time - do I need to? For example the DIY milk crate battery.

Thanks very much for all you do - all the great information you share, the excellent videos, all the help you provide others. Much appreciated.
I'm considering buying stock in a plastic milk crate company. Especially if you go into Production!
