Okay. Thank you. I would rather not fill this thread with a conversation about this, because it would be nice if it was just filled with user system configurations and measurements, but I see what you are saying and agree. It's not a perfect world. That said, I do recommend you take a look at...

( I HAVE QUALIFYING DATA ) In reply to the last episode: Well thank you for the information, I still think that LFP Lead Acid Drop In Replacement batteries are safe to use with non-programmable PWM Charge Controllers, Simple wall chargers, and other 12v charging equipment, including "dumb"...

Hi, here is an example of a "LFP Lead Acid Drop In Replacement Battery" Fully Guaranteed by the Manufacturer for 5 years, and I quote: "You do not need a special lithium charger or lithium solar controller" Guaranteed for 5 years by manufacturer! I recommend you watch the whole video and...

Thank you for your cordial reply and perspective. I respect that. I too would love to have double protection, especially with a system that had data ports so I could get the absolute most energy into my system and still have the layers of safety you mentioned. I do have a message out to the...

Well, I will run the test tomorrow with the upgraded cable directly into the busbars/battery and we will see. I still don't see your specs like I have asked people to help with. Do you think a real world data set would confirm what people are saying, and if so, do you expect people to give their...

Where are you getting that from? Have you actually watched any of Wills videos? Have you watched any of Hobos Videos? Or Lithium Solar? I really want to know where you are getting that from. The Professionals, Including Will, Hobo, Lithium Solar, DPoz, all whom test and evaluate hardware for a...

I'm not in a Cult, I'm in a SUPERCULT of 1, And don't forget, tomorrow I will still run the test as i laid out above. We will see. There may still be some/a lot higher vdroop in the line than people expect. And I still want everyone else's real world measurements - it can't hurt to have real...

I understand and I got it. I do have to say, some of the comments were completely disrespectful, repetitive harassment, and personal attacks. I have a thick skin, but look closely and you will see a pattern of me repeating my statements and assertions, not because I was trying to prove, over and...

am just all around tired, angry and bitter, but that did make me laugh - they do look like shit! I built that cable a couple years ago when I first started, its so stupid you have to spend 30/50/100/200/300 dollars on tools you will only use once or twice a decade. I really really would love to...

No Sht! I just realized that the wire is copper coated crap! Look at the very end of the strands... Do you see the aluminum discoloration!

Edit: Okay, so there are a couple things that I noticed that VERY WELL COULD BE CAUSING Voltage Drop on the line from the Charge Controller to the Battery First Picture: Janky Wire Connectors, do not look to be copper, maybe aluminum - Also, a couple strands are not in the connector (Did a...

Whelp, Partials Concession Speech: I was partially wrong. I'm on it - I will update the post as soon as I have the pictures moved to the computer

Okay. How do you account for the Vdroop from 19v to 15v from my panels to the charge controller? Those wires are also in spec and industry standard. That is a massive vdroop, the wires are fine, and I am getting 95+% available amps into my battery and it is the hottest time of year. How do you...

Hey, if you can, if you have a qualifying system, can you give your readings. Ideally, make sure the readings are at peak sun, and your battery state of charge is low, below 70% - closer to 50 or even 40% SOC would be even better - thank you for your interest in this, thanks again...

I hate to tell you this, but you are incorrect. Laugh Out Loud, I'm just joking, I couldn't help myself, sorry & thank you Hey, if you have a qualifying system can you post your readings - thanks again...

Hi, thank you; I did google the Dunning Kruger effect. I will take that as a compliment, even though I realize it wasn't. But that is okay. There are a lot of contensious points that are being argued about, but at the end of the day, the only way to get real world data is if as many people as...

I do not have a fuse from the SCC to the Battery/Busbar. The SCC has fuse built in. This evening, very shortly, I will be swapping out the 8AGW for a 2'6AWG, and tomorrow I will take readings from morning to night. What is your system configuration, and what are the readings at the terminals...

Dear Sir, I beg to differ. The Battery State Of Charge IS very important, because the lower the State Of Charge, the more the battery will Absorb. Again, thank you for your readings. You, and maybe one other person, are the only people who have actually attempted to give readings, but I didn't...

Point of Fact: Maxwell's equations are relevant to both AC and DC Thank you for your interest in this. Do you have any data set that states the Charge Speed, vs. the Current Speed? Do you have any equations built into the Ohm's Law in regards to the the Quantum Mechanical Principles in the...

Hey, thank you for that information. That is very clear. Can I ask you what was the batteries state of charge? I don't want to re-repeat my questions, or requests, but I did post this Thread, and if you could make sure the battery is sufficiently depleted & take the measurements around 12/1pm...

Hi, well yes, totally agree that there is resistance, and I am addressing that - thank you Please, please, please watch the video. At 17:24 they talk about the speed of "charge" vs the capacitance of the conductor. At this moment and several other times in the video, it is clearly highlighted...

cable was "added to cart" but I got distracted by everything else on Amazing and i forgot to pull the trigger! lol I have a #6 cable that is connecting my 2 old lead acid batteries in parallel, I will use that, but its been too hot and I am busy with a thousand things, and if i get to it, it...

Oh, Hi, I thought I made it clear to you and the others on this forum, many many many times that I am swapping out the wire with larger wire and double checking the connections - but just incase you missed it, I will state it again; I am upgrading the wire and triple checking the connections...

Thank you for your information, it has been well received. Can you please help us all by giving your readings as outlined in this post - thank you for all your assistance https://diysolarforum.com/threads/help-needed-if-you-have-a-1kw-or-less-solar-system-w-lithium-iron-phosphate-batteries.46036/

Hi, yea while I do have the allowable voltages cranked up to eliminate the charge controller from being a bottleneck in any way, as I said before, my batteries and never full when in use, and when I am not using the system, i charge up the battery and turn the system off. I appreciate your...

You seem to be the big brain on this forum, respect intended. Does "Charge" flow faster than "Current" If, "Chare" (for practical purposes) flows instantaneously, and "Current" flows A LOT SLOWER, would it be possible to explain the Vdroop on a line? I am not as technical or advanced as...

I will be the first to share my values Charge Controller: In App & at Terminals - 14.44v Img 1 & 2 Battery: In App 3.4v - At Busbars, closest to terminals I could get & before the BMS: 13.51v Img 3 & 4 1. Panel Size & Specs 6x100w Solar Panels Parallel 2. Charge Controller Specs 40Amp MPPT...

HEADER: FOR DATA GATHERING PURPOSES, PLEASE LIMIT THE COMMENTS IF YOU DO NOT HAVE THE REQUESTED INFORMATION – THIS WILL HELP THE PROCESS OF GATHERING REAL WORLD DATA – THANK YOU If you feel like commenting on this post, please at the top of your comment state: I Do Not Have Qualifying Data –...

yea, its late, I can't wind down, but I can't think anymore either. I hope to tear into it tomorrow - hope its not too hot. Thanks again for the great community and all the details, I really missed a lot of points and I think growing pains are good. It will mean I have a rock solid system - the...

Disclaimer: The next statement is a tongue and cheek joke/hypothetical analogy/conceptual conveyance of (its way to late tonight) far-out concept My Battery is a Black Hole and the Event Horizon is somewhere on the line from the Battery to the Charge Controller! lol

Hi, yes, others have pointed out that Browneyes statement didn't reflect the large 1 volt delta that is being seen from the controller terminal voltage to the battery terminal voltage. I have been working on thanking everyone for their help and learning as much as I can from this great...

Oh yea, man. I totally agree with you; that sweet spot of 3.45 for both charge and disconnect voltage would be great! But I recently have been running in parallel a second super cheap 200Ah Chinese Battery with no BMS App or settings, and so, I picked 3.55v - a balance between the batteries. I...

Yes, there is a "boost" voltage - see pic Hey, while I got you, what are your system specs? Can you yell me how you use your system &, if you can, under peak sun, tomorrow, please take a reading at the terminals of your Controller and Battery. I am trying to build a dataset for reference...

Hi, when you say "ground wire length" are you talking about the "Black Negative Wire" - if so, it is the same size as the Positive Negative Wire. As for a "Ground, Ground" - like in modern home AC systems. There is no ground from the panels to the controller, battery, or inverter. They are all...

Oh, hey man, Thanks. Yea I just want to say thank you to you all everyone who has been so helpful with my system. There are many issues to investigate and resolve. but as I said to several other people, I will be upgrading the wire to high quality 6AWG, and I will double check, triple check...
