P.S. whoever that guy is he is all right * He saw a risk * He called it out That's the most you could ever want from a mentor. -methods

Heard! I will test this immediately. Earth ground is extremely important, and my high voltage has no business being on it. I will measure the following * 420VDC+ to frame * 420VDC- to frame * Frame to frame on every single panel, for continuous earth ground on all framing material! * Rod deep...

Here is a teardown of some Amazon DC Battery Breakers. I already reviewed the higher voltage units on my 600A discharge table. These are for a different application. NOT A PROFESSIONAL TEARDOWN (obviously) Part 1 Part 2 Those are being evaluated in this rig, tying 42pcs of 2KWH 16S LiFe...

I am going to paint this camo. Then the government will not be able to find me, and I can wire my 42 individually BMS protected batteries in parallel without worry. I dont know what this thread is, but I am going to scroll back to the top. All I heard was Camo Solar Panels (LOL) -methods

P.S. I do not know what "EG" is but I presume you mean some sort of thermal self discharge? Like they are dumping into themselves? AFAICT the low output is directly related to the damaged glass. Explain what you want measured and I will use a Scientific Method (as best I can) to reproduce...

I make no claims other than that I ran a Scientific Experiment. Coming in I had 0% Experience. . . and I learned everything I ever wanted to know about shipping, measuring, mounting, monitoring, etc. It was a very cost-effective way to learn my way. I am VERY GLAD that I did not start out...

I don't post much but here are my results after surviving 1 season with the cracked 465W panels FACTS There is a flexible protective layer under the shattered glass and I got no "water rot" (ingress) at all in any way. This is thru dozens of heavy rains, freezes, getting hosed down at peak...

disclaimer IF You wire 120AC to the intput THEN The output of your Auto Transformer will be 60V, so not something you can use. The only time you would wire the input to 120VAC is if you want to use the unit ON THE BENCH as a current limited battery charger. (Since we are talking about...

Good Answer, I will validate it here when I have time. It had not occurred to me that Pass-Thru would run coincident with battery charging! QUOTE: https://diysolarforum.com/threads/spf-5000-es-wire-size.33245/post-408367 GOOD CATCH I did very little validation on Pass-Thru and it never...

PCB Way clarification The quality isn't so low that you can't use the parts. It's totally fine for prototyping. I've made many boards there.... And it's so cheap as to almost be free. All I'm saying is that... If you're used to high quality, you can see the difference in the pcbWay process...

Increased output from 1,650W to 1800W with a dry cleaning. Got that up to 1900W going wet Switched from 1 hinge for two panels to a fixed 2x4 and two hinges a panel So sketch bombing up the hill 1 panel at a time in the AmpTime 100Ah cart Bottom is a $2 clamp Top swivels the 900W...

Yep * Two layer * Top only * No smaller than 0805 * No smaller thant TSSOP * No BGA * Always buy a stencil * I solder paste everything* And yep - the houses will steal your IP, and other companies have access to the houses. When I care I obfuscate * Build landing board at one spot * Build...

Pushing hard on the IoT excuse - I need something REAL to monitor, otherwise I can't get excited about it (done it before). Although I had a lot of help getting up to this point (cheated) I did this entire phase of the job as "One Man, Locally Sourced, No Heavy Equipment" * Carried the solar...

No signs of ingress damage thus far. Survived several (many) freezes Coatings are 20% delaminated, I would NOT spray paint my cracked panels... Not without perfect surface prep and really good materials! ... I have 18 more to go up as soon as I can finish wiring and mounting. The full...

52.5% of nameplate 75% of derated expectations Real numbers * 1 panel destroyed by wind * 1 panel punctured by power drill * 3 panels binned our for very low output Fact * Visual appearance NOT good indicator of performance! I have 2 panels in my back yard. One hit hard with a hammer and the...

On my way to collecting data, progress report * Pulled 250' of conduit for the 18 panel array * Doubled out-shack battery from 4kwh to 8kwh * Binned out-shack (pulled three panels to side) * Sank 2 of 9 poles that will hold 2 panels each Numbers 460W SMASHED Jinko give up about half of...

OSH Park is actually a US PCB company (they don't send out to China) and they are competitive with PCB way @ higher quality. If someone has information showing OSH Park is sending out overseas post it here please. Sunstone is if course US based but they are no longer competitive in their...

When you take the carburetor out, it is really easy. It literally takes like 1 minute. There are a lot of teeny tiny holes... You can clean all of them with carburetor spray. There is one port that you won't be able to clean! The only way to get to it is to remove the enrichment screw...

Now... I got way off Target here, deep down a rabbit hole. My goal (lol) Is the collect the field data in mongodb Atlas. I will of course make the data public, but first I have to prove that what I'm doing is honest work. I am not trying to sell anybody anything. * This is not newfangled...

I prototyped mounts out of shingle mount kit parts from signature solar. These obviously aren't what I'm going to use, but they allow me to grab the panels, rotate at the top, adjust mounting point... Remember that a prototype never looks like the finished goods. What you want is something...

Suppose stock is a nice thing to work with. Round* Aluminum is used for many reasons * Lightweight * Easy to cut and drill * Fast with a bracket type of system If you're on the ground and can tolerate weight, if you know how to drill Steel, if you have time... 2 inch steel angle iron in...

No time, from phone * The arbitrary setup is producing 65% work That is imperfect angle, at the worst month, at midday, with dirty damaged panels, reasonably well binned. * 460W nameplate * 380W work rated at my location * 65% of the latter number That's the reliable work that I can extract...

For future I agree with the contributor who suggested cutting the harness and lap soldering a pigtail in, to a standard you're tooled up for. I rarely hunt for highly specific connector mates. If you calculate your hours spent, now and in the future, it usually works out to be a better value...

Something like this appears to be value engineered to the max. We're going to go ahead and drop 10 poles in the ground... 2 3/8" standard fence pole. That means I have to mount my panel sideways - so something like the bracket shown above should suffice. I'm on the lookout for some cheap...

If you want to rework a version one for clean readings you need single pole, low pass filters on your ADC inputs. I don't know offhand if an ESP32 uses 10 bit ADCs, but ALL microcontroller raw ADC inputs will perform poorly without an LPF. As close to the ADC input as is practical, wire a cap...

If you get the pin to pin Pitch correct... You can often cut the plastic housings to match. With 2 rows of more than 10 pins... the friction alone will hold the connector together without locks. Often times a connector like that will only come with a practical mate that's PCB mount! There...

I already know that will fail immediately, so... I'll wait to do the destructive testing until I finish one more round of bracing and load spreading. Also Obviously the linear actuator on that setup is pretty useless. I just wanted to play with it. ... Tension wires, springs... Er I don't...

On the first go I lined up with the diode boxes on the back instead of the split in the cells on the front... So I'm off center significantly. Sweet! New holes won't be bothered by old holes ... The stiffening l bracket material I bought was woefully inadequate, to the degree that I did not...

Confirmed our Soil Samples When you are drilling in this direction it's absolutely required that you put a backer behind the drill. You don't want to find out. Look closely at the picture and you'll see that I'm holding a metal bracket behind the pair of brackets I'm drilling. I'm drilling...

Super easy dig, took no work. For perspective, 6'3" 185lbs That above is a LONG way down for this soil. We hit clay. Totally overfilled for the quantity of concrete we had on hand. I had to get real clever after that... So we'll just say it's not up to code (any code, anywhere...

For an honest 24" hole, A 50lb sack is not nearly enough. -methods

As always the Home Depot website had almost no correlation to the Home Depot shelf stock. We went way over budget for this prototype... But that's to be expected. 4X to 10X is what a prototype costs. Now to do it, pics later -methods

Time is 0900 I have been up working on this since 0300. Now that everyone else is just waking up, lets see if I can actually GET SOMETHING DONE... before everyone else takes their morning dump. -methods
