I am starting a thread specific to he Heltec 200A Smart BMS with 2A Active Balance. 200A max charge. 350A max discharge I have 4 of them and I bought them from the Alibaba Heltec store here - https://www.alibaba.com/product-detail/14-24S-200A-Smart-BMS-with_62544207027.html edit: I forgot to...

My 66 Deligreen EVE cells arrived today in 17 boxes I am happy to say that the boxes are in pretty good shape. One box was opened by customs. I opened that one and another one so far. One thing I noticed is a "Made in China" sticker right on top of each cell. I am happy to report that they...

Sol-Ark 12K, 2.5 years no failures. Damn good thing because I don't know what I am doing and I don't have any help except Sol-Ark. I never call Sol-Ark. The Sol-Ark is easy to set up and it just works. I was getting some annoying fault codes when I first set it up but they went away. I never...

I made a little progress today and mounted the Solark, transfer switch and AC disconnect. Nothing is connected. Putting that 80 lb beast up myself was tricky. It doesn't look so huge in my picture though. I moved the smaller transfer switch out of the way and mounted the 10 circuit Reliance...

Make sure the busbars are flat with no burrs. They are stamped and some aren't flat. Clean everything with acetone. Put a thin layer of Ox-Gard or NoAlox on the terminals.

I passed! ? On to the interconnection agreement and bidirectional meter.

My bi directional meter was installed today. The electric company didn't do an inspection. The permit inspection was good enough for them. I am fairly sure I can turn on grid sell remotely but I want my wife to be home when I do it.

Finally got them all out of the boxes. The only thing I noticed wrong with these cell is the corner of the black cover got pealed back on one of the cells from the box customs opened. I'll stick it down with contact cement. I also got 2 odd cells that have a different format serial number. #57...

Happy New Year all. 5 1/2 hours til 2021 here in Florida. I must say I have enjoyed myself here on DIY Solar Forum despite the gloomy 2020 Wishing for a better 2021! ?

Here's some pictures of my latest setup. This is an evolving work in progress. I moved the BMS and shunt to the back so I could get all of the balance wires out of the way. The + distribution bar has a 100A MRBF fuse. I'm still deciding what to do about Class T fuses. I don't like the serrated...

I set up the HMS-2000-4T-NA with 8 320W panels and no gateway. I AC coupled it to my Solark 12K. The install went smooth and it works great.

Will, your inspiration is making he world a better place. I saw your Maine Coons Will. My wife and I have two. This is Nora

I finally got two batteries up and running parallel. They are connected to a MRBF fuses until I finish setting up 100A class T fuses for each pack. I moved one BMS to the front but got the balance leads out of the way pretty good. My solar panels and Solark are supposed to arrive today so I...

My batteries are only for when the grid goes down. So far after 2 years the grid went down for 2 hours. I have over $10,000 invested in batteries. That's $5000 per hour. It worked and is worth it.

This video talks about calibrating the YR1035+ It also goes through the menu settings. His menu is in Chinese though.

That group was created 2 years ago. I'm not so sure you can call that looking for new business. My guess is that Michael got himself into a situation that he never will be able to fix. He never set out to do anything dishonest

I finally started working on one of my boxes. Here's the wheels- And here's my grade A cells with no bulging-

I could cut my wrench in half and put a fuse in it.

I made up a bunch of cables so I don't have to tear down my serial pack when I want to charge parallel.

I finished my top balance and tore done the parallel setup. Now I will loctite my studs in before switching back to serial. I'm using red Loctite 263 which is for studs. The studs are supposed to break off unless I heat them before trying to remove them. I took all of the studs out and...

I am fairly sure the causes of fires has nothing to do with bar codes or slightly bloated cells. I am also fairly sure all of our cells are factory rejects. Otherwise we would have to pay 3 times what we pay. Some factories destroy the barcodes so they won't have to honor warranties. I have no...

don't feed the trolls

All of the major installers and manufacturers would benefit from this. And progress would slow because DIYers make stuff happen fast.

I see all of the debugging going on around here and I think the companies that make the parts would be smart to pay attention. You guys are working for free. I am far from an expert but from what I read Chargery is pretty good for the price. Especially for high amps. Some things aren't right...

I have the Solark and PV up and running.

It is amusing that DIY batteries are being discouraged now. I think the danger makes it less worthwhile to DIY now that the price is coming down for prebuilt safe batteries. But I feel like I have a secret skill that I will continue to play with. I try real hard not to make mistakes because...

I bought 66 280Ah EVEs with no problems. It was a little scary but I wouldn't hesitate to do it again.

I finally got around to turning on grid sell. The display showed over 5000W going out to the grid. It will be interesting to find out if all of our loads will be covered. I think I should be pretty close. Extra would be better since we plan to add an electric car or 2.

I often post what I think is correct hoping someone will correct me if I am wrong. And I assume a lot of others do that too. Another issue I see here is the Watch button. People including myself often toss in a few words because it is just as easy as hitting the Watch button. Those two things...
