But did you have a Merlin modem?LOL... lucky you... I had to use a soldering iron to build my first computer. Not just for connecting bits together, but soldering all the components to the PCB... Yes, I am that old

I trust that is a sarcastic "thank-you"... 1.5 years with no power ! OMGFirst, for 1.5 years I couldn't get the micro inverters to turn on and produce power at all. Then Enphase released an update to the firmware that fixed this issue. Thank you Enphase.
Just to clarify, this has to do ONLY with their off grid operation. When these inverters were grid tied they produced power as they should. They operated with basically perfect reliability. It was only when "cutting my cord" to the grid that I had problems.I trust that is a sarcastic "thank-you"... 1.5 years with no power ! OMG
Possibly you’ve over complicated it? Can be as simple as lining the cells up, crimping rings on the balance leads, placing the busbars and screwing them all down.This is an anti-DIY message specific to DIY batteries, so I apologize, but my message for the masses is, unless you know what you're getting into, consider buying a pre-assembled battery.
Deciding to DIY my solar battery was one of my worst mistakes ever.
I'm still not done yet, and so far the project has wasted about 12 million hours of my time.
Originally I was going to buy fully wired batteries in a box from Amy, but was told the boxes were too big and couldn't be shipped to my country. So stupidly, I figured I could do all the boxes and wiring myself.
Even for pro-level handymen, to do this right, with all the research required, the fixtures and compression and flexible busbars and sizing and building the box and top balancing and the BMS and the fuses and wiring... etc. etc. this is a really big project. For the record, I happen to be a pretty crappy handyman. So maybe for some of you this is a walk-in-the-park.
But my message for the masses is, unless you really really know what you're getting into, buy a pre-assembled battery. For the vast majority of people who are working for a decent wage, when you figure in the cost of your time, a DIY battery doesn't save you anything. I guess if building one of these is your idea of a good time, then go for it. But in my case, I'd rather spend the time doing other things.

No I get that, building a computer is easy, I didn't mean to compare the complexities, but the broad strokes of it all. But with the amount of time you've spent, I bet you've learned some stuff along the way, so maybe not a complete waste of time
i have mine compressed to raise cycle count, to keep the pack neat, and to bring my aluminum plates in firm contact to transfer heat in the winter from the heating pads. I used spring loaded rods to put a variable load that starts out at 10PSI at 30% charge and climbs up to 16 at full charge.There's nothing wrong with that. The only reason why I have mine somewhat compressed is because it takes up less space.
Hmmm... thinking back on some of my worse mistakes ever. Nope can't do it. Too gruesome.
Are those the 180Ah from batteryhookup?I recently completed my first battery build using nylon case CALB cells. I used a MRBF terminal fuse and corrugated plastic separators.
Do I qualify for "CHAD" status? Please note it is only a 12 volt system.
Windows 3.11 for workgroups... that would have been around 1993 or so...Anybody build a pc when windows Me was the operating system of choice?
Remember building pc's when windows 95 was first out?
Or BEFORE 95? Vista anyone?
Yeah... i love solar!
My wife's first husband, big into computer overclocking. Ended up drilling into freezer section of their fridge to eek out more performance.....so compared to that my solar shenanigans are of very low concern to her lol.that would have been my first marriage!

Yes so consider me out of the running for any experiments like, "can a Victron SCC that's placed in a freezer outperform one at ambient 75F thats approaching the temp of the sun due to less derating?"the lives we live huh?
Dunno, might be worth the doghouse for a night or two to figure that one out.Yes so consider me out of the running for any experiments like, "can a Victron SCC that's placed in a freezer outperform one at ambient 75F thats approaching the temp of the sun due to less derating?"
I do have a chest freezer I can empty, what happens in the power shed stays in the power shed ...Dunno, might be worth the doghouse for a night or two to figure that one out.
Why not wire oversized in that case so that if a battery or two gets pulled, you aren’t self limiting your powerConsidering that buying prebuilt batteries would have cost me about $9k more, a couple of hundred Dollars of waste is not so bad, I think.
Also by using the savings on extra battery you can reduce the size of wire in most cases.
Example I have 4x 280ah batteries with 12kw inverter. The most one battery will ever see is around 60a. Wire size for that is reasonable
You could do that.Why not wire oversized in that case so that if a battery or two gets pulled, you aren’t self limiting your power

Or both. lolYou could do that.
Or buy more battery
Yeah, I upgraded TONS of systems to WFW, huge speed improvement over 3.1 disk cashing for the win!Windows 3.11 for workgroups... that would have been around 1993 or so...
