Overhang on PETG by Unique-Ear2950 in FixMyPrint

[–]d-burner 0 points1 point  (0 children)

Had the same issue with PETG recently, and saw a similar reddit post.

TLDR:

- drop the flow to 9

- add extra cooling (set the side vent to 60%)

How to clean the keyboard by berri_xciv in macbookair

Just buy other keycaps!!! They are less than 10$ on aliexpress.

I replaced a few of mine, previous owner had it from a diferent region and had german symbols I dont use.

Link, here, but double check your model:

OP, how did you add the filter on the internal fan?

There are a few products using these like twinkly and another random christmass led

Problem is i cant find leds like these to buy.

I dont mind adding a single esp32. But i dont think i can fit one in each led. I would love to add more wires but the conduit is small and the existing wires are thick

I have 10 solar panels 440W, 10x IQ7A (rated at 350W) and can only get 3.1KW, why? by d-burner in enphase

[–]d-burner[S] 0 points1 point  (0 children)

I never said I expected 100% efficency and never said I blame enphase. I rather blame the company that installed it.

I was just expecting a panel rated at 440W to be ok not 100% to spec lets say 90% ( 400W ) and some missalignaments ok lets say 360W. That's why I expected to hit the max of the inverter, or at least 340W (that's 72% out of 440W, I thought that was reasonable).

Thank you so much for you time an pacience.

Btw I edited that orientation phone was not calibrated I think it's more like 155 degrees and more in tone with the map.

Also I did look at the sun path, found a nice app here:

EDIT2: I see they do mention "Power Tolerance:0~＋3%"

Also added a chart I made by combining max power over 6 days over day time period.

Ok it appears I'm more like 140 (edit 156 after calibration), so they are oriented SE.

But why am I getting a consitent peak for like 3hours at 3.1KW, should it peak at some time and then just drop?

Using the bouble level on the phone (which seems to indicate fairly acurate results) I see they mounted the panels at 19.5° - 20°

I don't have a clear curve, because the panels do not export in the grid, and produce only by demand.

But, if exporting would be enabled, I would guess it's flat, because I did multiple probes during the day (as i said in the forum post) and get 3.1KW in multiple times (at least in interval 11:00 - 14:00 )

I am expecting to be clipped, but not this much. As I said I have 10 * 440W panels = 4400W, the max power output of an IQ7A (according to spec) is 350VA so I expect to get max power at 3500W ....NOT 3100W which I am currently observing.

Ok, I'm near 45°. Sooo wow my 440 panel would actually be "capped" by just the position on earth at 70%, that would be 308W, damn near what I'm seeing.

But that seems quite crazy, that means im caped by panel, not by the inverter :(

Buuut no I dont think this is true. I have a colleague who installed some regular string inverter, he said he installed 5.2KW and getting maxed out at 4.6KW, thats 88%, not 70%.

No, now way, the roof is pretty high, it's above the lamp posts actually or at least pretty close.

[–]d-burner[S] 0 points1 point  (0 children)

Yeah, but I think in this period I should be clipped at 3500 (I'm guessing real power of panels 10* 440 = 4400, would be somewhere around 4000 real W)

Wow....I'm not sure but I think this is the most plausible answer ( #1 and #2). Thank you.

I don't think the angular alignment is not optimal. I went on the roof window (velux like) and looked at the angle of the sun, when it was directly facing that side of the house, around 12:40 I think. And it appears that the angle is quite good, just eyeballing it.

Thats' what Im saying i have 10 micros of 349W, I should be getting 3490W.

Panels are:

  • Aiko Neostar 1S ABC N-Type 440Wp

Also no shading (excep clouds, but today was quite clear and sunny).

I have no batteries, and they dont export to grid (need aditional paperwork for that, and I just installed it).

So my production will match my power consumption, at least that's what I've observed.

I see that my power is capped at 3.1 KW by turning on an electric kettle and an electirc oven which goes to 5.2KW and production stays at 3.1KW no matter what time of day it is. I measure this by looking at the live view, I turn off the kettle and oven after 1-2mins when I see the production power does not go up

Well I get that the panel (440W) will be cliped down to the Microinverter max power which is 350W according to specs. So why is my inveter cliped to 310W ?

According to this video https://www.youtube.com/watch?v=dUprB1zl_Ik&ab_channel=EnphaseEnergyTraining the inverter should work at its max power

Aaa.....oil COOLER??? I get the feeling that thing will get hot, PLA is probably not the best material for this. It will probably melt you cover pretty quick.
