Friday night around 45 parallel in western mountains of Maine looking due north, iPhone 14 camera on long shutter night mode way over exaggerated, first and last are more inline of what my eye actually saw.
I’d describe it as a strong dusk “glow” that hung around with some colors, I was take...
4 230ah cells arrived with BMS, impeccable packaging as previously reported. All cells perfectly flat and square

4 business days from ordered to delivery. Kinda wish I ordered another 4.
Solar makes sense (always will) when you self generate and self consume.
Now they are just making it financially sense to install that battery easier for your ?
I will say they need a special rate for “critical peak feed in” rate so your battery will pay for itself that much faster.
“Oh your...
What’s the clearance of those bus bars, 1/4”? That’s sketchy as shit right there.
Such an odd arrangement.
Also if the plate is bowing that means crazy about of pressure on the corners of the end cells, bad mojo can happen.
IMO Tools are never factored in DIY projects, only consumables going into the project.
Tools will be reused countless other times on future project and another excuse to go shopping that doesn’t involve me waiting for the wife to leave the dressing room.
Cable and crimping high current...
Even if the testing shows unacceptable loss of life over a years usage, what are you gonna do? Demand a buy back from the vendor? Throw it in the trash?
The more and more I’ve seen people run “tests” being concerned about every AH/Whr, the more and more I’m happy with my head in the sand...
With seasonal loads, it’s a crap shoot at what loads come and go. I really thinks you give the utilities and the kilowatt cops too much credit.
I’ve ranged from 400-800Kwhr over the course of a few months.
Moved the power wall to camp this weekend. Still haven’t connect PV but the seasonal move went well.
Also tested out the 24v diaphragm water pump, sang like a dream up to 50psi a 5amp draw, but does have a small weep on the output.
Current Connected order placed. 24v MPII 3k, Bluetooth dongle, and USB programming cord ordered.
With the price drop this year on the MP, the extra plugs in was free and I still saved a couple $ waiting.
Now Victron will prob oil a Tesla and drop prices again, lol
Now the waiting game.
MPII is out for delivery, I routed it to fedex store as I wasn’t going to be home day of delivery that required signature. So now I pick it up at my lunch break or in the afternoon.
Unprepared city folks won’t make it 5 miles from the city boarders before they die of exhaustion and lack of avocado toast.
Except for those peloton folk (assuming they have an actual bike) then they will give up after 100 miles or so.
I don’t know why people are so obsessed with harnessing each watt they can.
Size the system to handle 5 days without sun during the lowest solar production months and call it good, if not double it for 10 days storage ?
So it works at room temp but needs a diamond press at 39million pounds to create a pin head worth of the stuff. Without that pressure it’s junk.
I guess it’s one step forward with a marathon to go.
