"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...

That your pump will pump down to -30 and your guage reads properly. Now find your leak

I hate it when that happens! Me after the stroke of midnight at Y2K: "Anyone want to buy a generator?" 8*)

No good deed goes unpunished. Illegitimi non carborundum I used to have a T-shirt that read: does anal retentive have a hyphen?

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.

I can only imagine how my condo assn would respond. I’d probably have to use a stopwatch. 🤪

I dunno, you reported this Wednesday, they've had two days, in my labs it'd take about 2 hours to replicate the issue and start the ECO process (they've already patched the manual). Maybe they are still understanding the engineering issues involved and deciding on the best solution, but I'd...

If they are in parallel the voltages must be (are) the same. Where are you reading SOC when in open-loop?

Anyone else get Omega Man (the original) vibes from this? 😁

You’re not wrong. This conversation has wandered far afield into “how could this happen” and “how could this have missed testing and/or engineering review”, and “how come nobody else saw this” which doesn’t detract from “This should never happen”.

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!"

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...

Some Amazon AC meters, cheap and useless.

Don’t dig a foxhole just for your solar stuff, it’s probably less expensive to add a utility room. Put it in a leanto attached to the house. At least that won’t flood.

And if your batteries aren't full you need more panels.

So buy the panels now, and if you don’t move in three months, they will be more valuable and you can sell them for a profit.

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

There you go with that “should” thing again. 😁 I can’t buy V1 and I want Chargeverters, so I preordered a couple of V2. 🤷‍♂️ If EG4 fixes their firmware I’m happy, if they don’t I’ll live with it or figure out a workaround or something. Heck, if my system has enough margin I may not even need...

There's No Kill Like Overkill!

Hey, I just escaped from Taxachusetts, now I is Florida Man! 😁

That’s QA’s whole job. Test for everything you can think of and everything nonsensical and every weird corner case.

Either share the bills with them or let the power fail in the middle of the night. 🤑 #SkinInTheGame

At the end of the day, the only income stream the power company has is the rate payers, so one way or another the ratepayers are going to pay the cost of any grid upgrades.

You are overthinking it, doesn’t compare to most electrical heating appliances (240V water heaters, stoves, ovens, etc) Heck, if it plugs into the wall it’s gotta be under 15 amps, 1800W

Spending money on parts and then losing track of the project in the months that it takes for everything to arrive. “Hmm, wonder what project (in what country) that’s for, unless it’s for general stock (in which country?). I’ll just put it over here till I remember.” My wife swears she brought...

Look on Amazon for Cord Hider or Raceway, also available at most Big Box hardware stores.

The subject is LFP, the above appears to be ‘regular’ lithium

What could possibly go wrong? 🤪 I like the separate Romex idea better, then it’s trivial to switch to all 120Vac

With the right socket you could adjust the color temperature by hand! Now we need a new UI for the bulb, rotate for color temperature and lift up and down for brightness?
