Hi. I'm thinking aluminum for my bus bars too. can you give any info regarding how you decided size? I've heard 4x20mm, and and also 10x30mm. Thanks -- Steve

Thanks.?

I believe this because crimping presses the conducting metals together with great force, while soldering may "bridge the gap" between the conductors if not crimped, and the solder itself can end up as the conductor, and is a relatively poor conductor.

I have wondered if crimp-then-solder could be problematic. Since the wire and connector must be somewhat dissimilar metals, couldn't heating up the both of them to add solder decrease the contact area (from the crimp), and increase resistance? I don't really know of course and admit I am an...

Hi. Not to be rude or nosy... may I ask if there is any word on your "state of reflection" WRT the BMS you have been discussing? :)

Thanks for the reply. I appreciate it. I'm trying to put together my own 16 X EVE 280Ah, 48V system with only a digital design and software engineering background. This BMS design from @BiduleOhm is definitely looking interesting, based on the problems I've seen with some of the less expensive...

Do you have something between the batteries in your box? I've heard that if the batteries rub together long enough, that blue outer cover breaks down and the metal case is exposed and can short to its neighbor. I'm a newbie, so I'll defer to others, but this was told to me by a guy who runs a...

I wish it was for 200 or 300 amps. my EVE 280ah X 16 setup needs a bigger bms (I think! ;-). Thanks for this thread. -- Steve

Heh. I like this even if it's pointed at me. Buyer Beware.. Ended up with all my batteries after ~ 2 mo.

Thanks a lot for the response. Pretty sure I understand everything you said up to maybe the last sentence. WRT that, I think I understand you to mean that you don't want to check SOC using current if there is already current moving into or out of the battery (ie, current with current...

Just read this whole thread. As a newbie I have to admit it is mostly confusing. Seems like, in this case, we've defeated the purpose of using a forum to gather accurate and meaningful data. I wish there was a way to separate the wheat from the chaff as you say. Guess I'll have to just keep...

Thanks for the thoughtful response. I too am re-evaluating how batteries can help me out besides making very sure certain fridge items are always available. That was the first thing. Then other important things when power is turned off because providers can't yet deal with fire near their...

Hmm. Good idea. I knew I wanted the batteries to eventually use for some kind of backup but I also mistook them as a requirement to run my AC. Thanks. -- Steve

Lots of good information here for me to digest. Thanks a lot. -- Steve

Thanks for your help. Of course my comment was a joke up top. I'm used to being the only one who thinks I'm funny. I will look over your and other's comments and figure out what I need to do. This forum continues to be invaluable. Thanks again everyone. Couple points just FYI: I live in San...

So I think I'm probably confused again. Your fault ;-) I went out and bought about 15 kwh of batteries (cheap!). Now, I was thinking I would not use micro inverters because of the seeming extra step: from the source/panels it'd be DC-AC (micro inverter), then into the batteries its AC-DC...

Thanks again. The chargery definitely looks interesting, if a bit complex. That should be okay for me I hope. I need to get the BMS and I need to figure out a way to top these new batteries off. Looks like I may need a charger that delivers a good amount of amps at their low-voltage. Bought a...

Well I've got my 16 new 280 Ah lfp batteries. I guess I need to top them off but then I need to figure out what to do with an inverter and buy panels. Really feel like now, after waiting an extra month to get the batteries I need to get some panels and an inverter so I can make some electricity.?

I have now we received all of my batteries. Next step I guess is the top them off?

Finally received the last four batteries today. Box was in pretty poor shape including the tape having been ripped or worn off the bottom, and so the box was sitting on my driveway upside down. Opened it up and took the batteries out. They all look square and ostensibly like new. Sigh. Just...

I never said they had made good. See my comments elsewhere. Still waiting for this to resolve.

Thanks!

What a long strange trip it's been. Irritating as well. Only 12 of the 16 arrived. Then I told him I would help pay for air shipment for the last four. He said okay and then later told me that - oops - they too were shipped by sea same as the others. He said sorry again and told me he would go...

Thanks. From where?

See my post from a few minutes ago. I don't think I would trust this company.

See my response a couple minutes ago. My dispute is that I was misled.

I guess I disagree with that. When someone says here is a picture of your 16 batteries you just paid for and then you only get 12, and see that the picture wasn't even of the received items, and it turns out you have a 60-day wait for your items rather than a 30-day wait, that is not good. As...

Yes.

Thanks. Looking into that, but at this point not sure what is the fastest way to get my four units.

Thanks. Sure don't want to have to do that. Especially since the plan was always to increase storage and maybe help friends/neighbors build their own systems.

Well today is August 13th 2020. Surprisingly I received batteries today. More surprisingly I only received 12 of the 16 I ordered. The batteries looked new, and 4 I stuck the meter on were between 3.324 and 3.332. Now, upon completing my order, I was soon sent a picture of 16 batteries in four...

Hi everyone. Anybody know about or have experience/opinion regarding these panels? They are government surplus, used panels. I have to pick them up, which is fortunately pretty easy for me. 260 Watts. Looks like they're about 6 years old. Not sure how much risk there is or how easy it is to...

Well today is August 7th 2020. What would you (all) say is it good price per hundred Watts right now? I'm gonna also post a question about some used REC panels I found..

Sorry just saw this. I'm still waiting for a tracking number. I don't think that this wait is unusual though.

Still waiting on tracking number..
