Yeah that sounds about right. China: "Yes, you need to 3d print that part to assemble the 3d printer." Customer: "But I don't have a 3d printer, that's why I bought this one from you" <muffled laughter>

Right I think I'd be the same way but I still am not 100% sure my inverter is going to charge/discharge my battery according to my settings because my system has only been running for a couple days, so I'm paranoid and checking the voltage every 4-5 hours. I already came close to overdischarging...

Generally I don't mind certain DIY projects. I've been trying to analyze what it is that I hate about these particular projects, and I think it's just that I hate sloppiness and kludging, and it's so difficult to take sloppy things and make them clean and elegant like this LCD wiring. Does that...

If there is one thing I've learned in my life, it's don't buy a "kit" from China. It will never come with any documentation, and the things they will expect you to do to assemble their "kit" will just boggle your mind. We once made the mistake of buying a 3d printer kit from China. LOL. Needless...

I finally got the LCD battery monitor running. What a piece of junk. Cost me $40 + 3 hours of my time.. The wiring comes as a complete sloppy mess, different wires hanging loosely all over the place. Trying to wire in a power button, find a suitable DC adapter and connect it, and then secure...

I like this idea. Makes sense that it would work better. I'm going to try it when I connect to grid using the "clamp type" on my inverter.

Wow. @Zwy Could what @D71 said be related to your problem? I was originally planning to do 100 yard runs to my panels and was told I would need 8AWG to keep voltage loss to within acceptable levels at that distance, and I'm running lower voltage than you are. Long strings of 8AWG was too...

Ok that makes it super clear. Thanks much @AntronX

Oh OK I got it now. Thanks for teaching me that!

I recognize this is "clamp style" https://cdn-reichelt.de/bilder/web/xxl_ws/C160/WAGO_2604-1105.png I recognize this as screw type: https://www.camdenboss.com/products/img/CTBP9208_5FL.jpg Is that correct?

You didn't answer my question, and 3-6 months is much more no matter how you slice it. Why do you want to minimize it or call it easy when it's not easy for the vast majority of the population? But anyway, the OP can do whatever he wants, I've made my point. Good luck OP!

The numbers on PVWatts are labled in kWh, please see for yourself in screenprints above. Let's put it another way: Your electric bill says something like: "This month's bill is 2136 Kwh." Doesn't it seem unlikely you would be generating 80,000 Kwh in a month, which would be 40X your monthly...

I said it took me 3 months. @hwy17 just said it took him 6: When you say "easy" some people think of easy as like ordering a burger at McDonalds. If something takes some folks 3-6 months, would you consider it easy? "I just spent 6 months on an easy project" - Makes no sense, does it?

I think I'm going to try a hot plug. I like living dangerously. Let's see if I can Die Another Day. I mean anyway I have No Time to Die. Live and Let Die, is what I say. 😉

I checked Google image search for that keyword and I cannot distinguish "clamp style" from "screw type" They both have screws?

Easy for who?

I should add, I don't need to, or at least wasn't planning on physically disconnecting the BMS after powering it off. Just insert some plugs into it.

I have a 200A DC breaker between my batteries and the inverter (separate from T-class fuses), if amperage is 1A or less, can I just throw that breaker instead of powering off the inverter? Reason being, there's a green button on the Deye which appears to be power but it doesn't actually seem to...

I need to power off my BMS to install a LCD screen. I'd like to avoid having to precharge my inverter again. What's the best series of steps to power off the BMS? I'm thinking: 1. Remove load from inverter 2. Do this at night, when PV input is virtually zero Next steps I'm not sure. 3. Turn...

I'm confused. It looks like all the connections in this video are screw down terminals, so didn't he do the right thing by using ferrules? If you use a screwdriver to set the wire, that's a screw down terminal, isn't it?

@AntronX @rhino @timselectric @Skypower So anytime you have a set screw type of terminal, you should always use a ferrule? This is completely new information for me and means I need to redo some things in my system. Which brand or type of ferrules do you recommend? Can you also please address...

I didn't even know batteries communicated to inverters until after I had bought the wrong BMS's twice. Sure, if your time has a value of 0, or if this is a fun hobby to you, that changes things drastically. Either that or you'll never use them again. Like I bought a pretty expensive (used)...

Yeah exactly. Well, 3 months, if you don't count the 2 years my batteries spent sitting in their boxes unopened because I didn't have the time to do the project or I was waiting for one part or another.

Seems like I'm the only one on this forum with this opinion, so feel free to ignore me, but don't DIY your battery, period. Unless you want to spend 3 months researching, buying parts, and tinkering. It's way more work than it looks, and way more work than most here are willing to admit. When...

Does Seplos do a better job figuring out SoC than JK-BMS?

@sunshine_eggo What would be your recommended Pylontech CAN compatible BMS?

Looking for the best BMS that supports the pylontech CAN protocol, I have a Deye inverter. I do not want something recently released. For example, the newer JK-BMS that supports Pylontech CAN is too recent. I'd like something more stable. I also don't want to have to build custom wires for the...

If your array is 33.5kw, according to PVwatts you'll be generating 3,151 kwh for December. Which is still a massive number.

Checking again PVwatts. Assuming Castle Rock, Co It would take an array that is 850kw (850,000 watts) to generate 80,000kwh in December. Your largest panels are 550W. You would need 1546 panels of that size to generate 80,000kwh in December. No? I dunno, maybe I'm confused. lol. I've been wrong...

I guess I'm misunderstanding. How many kw is your solar array in total? 33.5kw?

Sure, whatever works for you is fine. I'm just offering a different perspective. Please keep doing what works for you. Your system cost $55k? Seems reasonable for what you ended up with.

Good one. Even the JK-BMS itself didn't come with a manual. Actually there is a manual, this is it:

With solar DIY anything, there's no way you only cry once. Once a day until the project is finished, maybe. 😉

Bought this display for the JK-BMS. https://www.aliexpress.com/item/1005004027834830.html It's got 2 loose wires (no button) for the on/off switch and needs a 12V power supply. Oh joy! Ok so questions: 1. When an on/off switch is 2 loose wires, you touch the wires together to turn the thing...

Great title for this post: This, or that, or wait, maybe that? Dre, creep to the mic like a phantom
