  • Post in thread: Does anyone know of a ChatGPT/LLM integration with forums?

    Kinda hope not, “AI” is known for hallucinations, correct answers that aren’t useful, and a lot of wasted time and effort. I have enough trouble sorting the wheat from the chaff without some automated process mixmastering all the text again.
  • Post in thread: Too many projects, now where did I put that...

    Never. No, wait, always. Wait till you get into the “Why did I walk into this room?” stage of your life. And don’t forget the “Took off my glasses so I can see better, but can’t see well enough to find where I put them down” paradigm.
  • Post in thread: Too many projects, now where did I put that...

    One of my favorites lately is opening a package and going “That’s neat, I wonder what it’s for?“
  • Post in thread: Has anyone had any experience of adding a Wind Turbine complete with inverter to a home that already has a Solar PV installation?

    My wind generator produced power at almost exactly $100/KWHR before I took it down so it wouldn’t fall on my solar array. 😁 Small scale wind is really hard to make work as well as you think. $2700 will buy you a lot of additional panels. 🤷‍♂️
  • Post in thread: Creating an off-grid GRID in Joshua Tree: 10 acres, 15 campsites each with independent solar. How do I connect them??

    Maybe run 240Vac around to make your own micro grid, and AC couple your panels to your batteries?
  • Post in thread: Timed pump shutoff to prevent continuous running of well pump?

    There are a bunch of different failure modes that the OP is trying to solve. The dropout-on-low-pressure switch will solve some egregious issues (broken pipe, loss of input water, etc) but may not cover others (faucet left on, slow leak, neighbors using too much water). I’ve got all kinds of...
  • Post in thread: Suggestions for whole house off-grid system?

    You may know this, but it’s not true. 😁 Higher voltages have lower currents and less loss, so high voltage DC string voltages are your best bet for the long runs. Plus you get to keep your ESS at the house. Just curious is roof mount is an option?
  • Post in thread: Too many projects, now where did I put that...

    And as always, having more than one residence means you’re positive you have A Thing but aren’t entirely sure it’s _here_.

    Rut Roh. I ordered a bunch of small panels to keep 12V batteries charged, is this the beginning of the end?
  • Post in thread: Confusion on meaning of Off Grid vs Grid-tie vs Zero Export

    My mistake: I misread the title of this thread, it appears to be: Please add to my confusion… 😁 Of course this entire thread is an example of why there is no such thing as an easy answer once you get past some of the basic inverter types. Not everyone wants to do simple grid-tie, or is even...
  • Post in thread: Circuit breaker fail.

    #FalseEconomy. So, tear it apart and tell us the results of your failure analysis!
  • Post in thread: Plugged hydro line?

    I like this test the best, you can drill and tap 1/8" or 1/4 NPT holes in the pipe and screw plugs into them to seal them off. Successive approximation (start at halfway point, see how far water shoots into the air, then do the half of the blocked side, rinse, lather, repeat) should find it for...
  • Post in thread: Small diesel generator...

    Just the uppers, or just the lowers, or both? And autostart requires a separate federal liscence? 😁🤪🤷‍♂️🙈 #IfYouSeeWhatIDidThere
  • Post in thread: Too many projects, now where did I put that...

    Absolutely! Then when you go to put the new one away in The Logical Place you’ll find the lost one. (And four others).
  • Post in thread: Philips may have created the best LED bulb yet

    I used to prefer the highest color temperatures until I had my cataracts removed (sepia filter removed from the camera) now my favorite is 4000. But yeah, can’t understand the preference for 2700, might as well light a candle. 🤓
  • Post in thread: Need a way to bottle or can excess solar production.

    If only there were some way we could use wires running everywhere to buy and sell power on an instantaneous timescale. ;)
  • Post in thread: ring terminals

    I usually fold the wire over if it’s too small
  • Post in thread: 35,000 SF Commercial Office Building

    Now you are on the wrong side of the meter, getting paid wholesale rates for all of the power you generate while simultaneously paying retail rates for your consumption.
  • Post in thread: Utility jerking me around.

    Sure, we all love "The Grid Is My Battery" aka Net Metering, but there's enough pushback from the power companies that it's feeling easier to just go completely off-grid, oversize everything (panels, inverters, batteries), and get a small backup generator for the really lean times. My favorite...
  • Post in thread: New Tariffs in the States

    You missed a step. When oil prices drop, it takes a lot longer for the 'expensive' oil to work its way through the refinery process and the other supply chains. Gas prices _always_ rise immediately on oil price hikes, but _never_ fall for weeks after price cuts.
  • Post in thread: 2MW agrivoltaic design - design constraints for inverter

    "Do you walk to school or bring your lunch?" These concepts are orthogonal to each other. You've got some of the concepts right, but there are a lot of missing pieces, though if your client is really going to build a student-designed grid-scale array, he deserves what he gets. Don't get me...
  • Post in thread: 4 X class solar flares to impact this weekend.

    I hate it when that happens! Me after the stroke of midnight at Y2K: "Anyone want to buy a generator?" 8*)
  • Post in thread: Live Ground Shocked 5 Year Old

    No good deed goes unpunished. Illegitimi non carborundum I used to have a T-shirt that read: does anal retentive have a hyphen?
  • Post in thread: One cell going over voltage

    They let you keep the old ones? In that case, float charging at an appropriate voltage that will cause them to balance for a few weeks (!) might be your first/easiest fix.
  • Post in thread: Too many projects, now where did I put that...

    Well, it's all in her name (Amazon Key can't deliver to more than one person at the same address, sigh), and she's the CFO, but "Oh, don't open that, it's a present for you!"
  • Post in thread: Semtive wind tubine

    My VAWT produced power at almost exactly $100/KWHR from the time I put it up to the time I took it down so it wouldn't fall on my solar array. Solar is a big win here. Well, to be fair, it has some residual value, I used one of the clamp fittings as a hammer to help open one of the boxes on my...
  • Post in thread: Need a way to bottle or can excess solar production.

    And if your batteries aren't full you need more panels.
  • Post in thread: Joe Biden Edition battery now available!

    The BMS in the Bigly Battery consistently over-reports capacity. 😁
