That’s what I did, mentioned Steve S diy solar forum, looking for an 8s case with single M8 terminals, jk200a non inverter BMS with display and 8 280v3 cells with dual terminals.

You mean you’ll be ordering another 4 cases and 36 cells in the next 6 months when prices drop again.

They run a Kraft paper in between the rubber and conductor. Either way I have 4 awg and 2/0 from windy nation, I’ll continue using it. But everyone has their preferences and standards. I was expecting green death or something horrific.

https://diysolarforum.com/threads/alte-out-of-business.82455/ Sounds like a merger and acquisition with rebranding is in the works.

My 230ah cells were 120 a pop delivered from back in spring 2022, lol, so it’s almost like this case is free and I’m getting 280s! I will prob have another $250 in other odds and ends to make myself happy, might as a USB charger and a class T or MRBF internal fuse, but still it’ll be a much...

They were in business for decades and one thing or another they recently closed up shop, they catered to DIY market from the beginning (granted they never jumped on the EG4 bandwagon)

I fear DIY community isn’t that big enough to support nation wide build out. Alas just look what happened to Alt E Store.

If someone wants to cause harm they can cut locks on distribution switches and operate them to isolate entire streets/towns. Been there, disgruntled customers were arrested.

they are installing three 50mvar sync condensers in our area (old ABB facility, gotta be good, it’s from Sweden), and the amount of screw up’s is unbelievable. They didn’t specify storage and environment controls of the rotating machine while waiting for delivery, so the stator has surface...

Just one case (single stud) and 8 280kv3 cells, jk 200a non inverter BMS. $1130 delivered to my door (260$ for shipping). I don’t have a means to handle a pallet. This will bring me up to 11kwhr for storage (8s230ah and now this 8s280ah) at the camp where biggest load will be a hair drier and...

And order/payment completed, now the wait. Thinking should be here by the 7/4 or at least mid July.

You have/or are getting a pair of 150v60a MPPT, but are only planning on running 2s3p at 50v to it? Why not do a 3s2p? Get that voltage up higher, no need to duck around with 8awg if your running say 75v and ~10a to the MPPT. Heck you could prob do 4s2p without concern for the 159v high limit...

I’m more interested in how you’re using 2-3kwhr a day in a yurt? I thought the whole idea of one of those would be to spend more time away from electricity and it’s cruel comforts.

Started the conversation to order a single 8s case with single terminals, with 200a jk BMS (non inverter) and 8 280kv3 cells. I’m almost half ass curious if I ordered two cases if it’s be worth my time. This will pair with my custom built 8s 230ah case for a minimal off grid camp with a MPII...

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...

I thought it was shipping containers stopping by various pacific islands, resticker, then continue on their way.

It’s not that much of a challenge to drill them out out, maybe 10 min total.

*did have https://new.abb.com/news/detail/98507/abb-completes-sale-of-remaining-stake-in-hitachi-energy-to-hitachi#:~:text=ABB%20has%20completed%20the%20previously,a%20stake%20of%2080.1%20percent. From what ive experienced, they’ve taken a Boeing nose dive in the past 3 years.

Most power transformers are delta high side wye low side, this way high side is balanced, and low side provides ground source for fault current.

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.

Sounds like you want to build a solar roof over the entire balcony?

Wake me when people in DC region are able to see the Auroras.

How bad was the voltage adjustment off by? Also you measured and adjusted that calibration with no load right, not even the inverter idling current.

Let us know what the DMM reads of the battery when the BMS says full. If you pick up a victron smart shunt it’ll estimate the remaining time depending on the current load. It’ll also track 100%

Yeah the smart shunt (non BVM) has limited range. I’ll prob have an Amazon tablet set up with victron connect this summer as a permanent install on a wall and I should be good knowing I have enough info for my needs.

My little acu-rite is 8 years old, was a Xmas gift. It lasted 5 years on 4 energizer lithiums, then 2 years on regular cheaper alkalines, last fall just tossed another 4 lithiums into it and will forget about it for another 5 years. It does have a solar panel on it 2x2”?, and when the suns out...

So 8 feet at 5.77/ft so what $50? so you intend on using this for DC input to a victron inverter? No AC output has that capacity. The cable entrances for my MPII have a little bend in the cables in there to make my 2/0 lugs sit flat. The lugs on the PBC boards with insulation around it...

I mean yeah it can work, it’ll carry current. With a lot of effort and frustration I can also pound a round peg through a square hole.

Linking a smart MPPT to the smart shunt, and having the smart sense voltage sensing lead closest to the battery terminal will negate any voltage drop or rise from the Smart solar terminals. If you’re pushing 70a of charging current and trying to get each cell to 3.45v any voltage drop won’t help...

2p8s Simple easy done!

I mean the guy does have the time, effort and tools to post thermal images of the battery and BMS working, but a simple DMM to measure actual battery pack and cell voltages against the app. . . .

What inverter do you have feeding the AC loads? What does it have for idle consumption? Is that the 68w shown in one of your screen shots?

He states it’s an inverter based mini split so inrush should be minimal. With JK having a “voltage calibrate function”, the BMS could be displaying 27.6v for the battery bank in the app, but actual terminal voltages could be 26v. Trust me, I was playing around with that calibrate setting and...

How many feet did you buy? I’d say you got your self a nice souvenir, maybe make some art work/jewelry with it? I would not use THHN 2/0 for anything DC related, just not worth the headaches and so much can go wrong. Just cut your losses as part of the education al journey and move on.

What style of wire did you buy? There are many different types of conductor that meet 2/0 awg rating. 2/0 THHN is mighty different than ultra fine stranded welding cable. I assume you bought it online, not at a local store? Mind sharing the link to where you purchased it from.
