Does slowing down gently with regen produce same power regen as break late and hard (polestar 2 here)

I got a UT181A (which also has data logging) because I was too cheap to pay for the Fluke 289. I'm happy with it. The main downside is the rechargeable lithium battery. I prefer being able to just swap batteries instead of minding some battery that's hard to get a replacement for and will eventually kick the bucket anyway. The color display might be more power intensive(I don't actually know) but it shuts off when logging anyway after a period of no user interaction, while the meter stays on. It will time out the sceen like this even when not logging but stay on.

Nice to see it living long enough to be upgraded rather than replaced due to malfunction. Especially as I myself have two SMA 3000TL inverters at home, manufactured around one year later than yours.

The only mistake that you had made was using Shimano Road Bike, Cables and Housings when that's a Hybrid Combo Mountain Road Bike with Mountain Bike Components not Road Bike Components. You need to replace with Shimano MTB Cables and Housings. The only thing connected to the Road Bike aspect are the 700c Wheels and Tires to witch there are now multiple Treaded 700c Tires available out on the market through several Bicycle Tire Manufacturer's, to be able to take you from the flat roads and out to the off roads and trails.

If you let it sit for a couple of minutes it will automatically walk down to zero

Buy WHY does a small shade kill so much of the output?

Totally cute!

What’s the PV in a circle sticker mean?

teardown but then reassemble and sell it! It would be a waste

RSVP Sunny Boy. A tear-down is less of a Viking funeral, more of a post-mortem. But I don't think it has to be, it could showcase the technology and innovation that went into its design, and how that made it such a reliable workhorse. A Sunny Boy Horse, if you will.

People wonder why PV isn’t very common in Vancouver, BC Canada - our electricity is just so damn cheap that the economics don’t make much sense. At $0.10/kWh, this whole system would have only generated $3800 in return. Makes so, so much sense anywhere which uses coal/oil and pays a lot more for electricity, though!

You mean to tell me you turned it on BEFORE you took it apart!!!! I think at least a non destructive teardown would be fun. I remember watching the video when you put your system up back when i was in grad school!

Maybe even a destructive testing? See how skookum it is built?

I have had a 1700W SMA Sunny Boy on my system since 2008 (16 years ago) and it has run without a fault since then. it has been on the west wall and display is now very hard to read but it has generated 26 megawatt-hours. it cost $10k back then but has saved me $17k so well worth it.

Does it have a chassis full of vacuum tubes strapped to the hood now?

Damn I remember the installation!

Teardown, of course. :D

Do we get a teardown?😊

2x Fronius IGs running for 15years here...

In South Africa we install solar out of necessity - personally generated about 5MWh in 10 months, starting with 4kWp of panels in June last year, up to 13kWp now, on my way to 18kWp. The panels pay for themselves, the inverters, and the giant batteries we're forced to install.

You're probably going to miss the quality / reliability of an SMA. One of the few manufacturers where you can disable all cloud rubbish, and keep your data local 👍

tear down + reverse engineering + explanation PLS

Almost 12 years from mfg date instead of tear down.. I'd rather see overload type testing.. 750v holy buckets how!? also if you have a IR camera.. that'd be cool to see it in operation. (but don't die) I think you've convinced me.. buying old equipment sounds like a worthwhile gamble.

It was good enough for Australia!

3:20 I guess plugging microinterverters into the generator input will not work. Usually microinterverters will NOT RUN if they do not see the grid voltage. And as a generator input is an input and not an output, there is no grid voltage for the microinterverters to sync on.

Stop using nvenc 265... Why are there so many of you who are either willfully ignorant or blatantly lying about this crap?

Wow already 10 years? It feels like you just set this up not that long ago. Time goes by fast these days.

Yes, teardown please. Thanks

I vote for a tear down that you still can sell.

Wow, so if that cost a grand, it cost 3 cents per kwh produced.

A detailed teardown would be very nice. Other than the efficiency due to better control and components, I guess that not much has changed over the years regarding inverter technology, so it would be very educational a teardown and explaination of how the various parts work.

Take it apart I say! I have the same inverter, the knock-on display is an odd but quite clever idea. Mine is missing the part on the bottom left with the one green and two red dots that sticks out (near where the DC cables enter). I have only been in the house for 6 months, it must have broken off at some point in the past. Not sure what that part is for?

Put the spare panels on your driveway...

I've got a 4kW version at my place of work. It's been giving perfectly reliable service since 2009, and is still going strong. Being in the UK, it's only produced 37,000 kWhr from the 3.8 kWP panels in that time.

I remember when you put it up all these years ago! Wow so much has changed in the last ten years. I'd love to see a teardown!

Teardown would be good. I’ve a 5kw of similar vintage. It’s been a champ.

tear it down please

Regulations prevent redeployment of 2nd hand solar gear for grid tie operation which is stopped cause there's a lot of good systems being replaced that could go to low income families but aren't allowed to

single phase people scare me. using all that copper and amps when you could use 3phase like normal people. but i guess some countries are special.

teardown please

o7. Good Job, Little Box!

Tear down tear down tear down! Why do you even ask :D.

cable guys old cable is unknown quality to them.i say its just any excuse to lie and mlik some additional money out from job. i would personally not hire such idiots

why not keep it as spare,why u brother removing it?keep it as back up
