  • Post in thread: US Customary Electrical Units

    Well, it seems to me slightly out-of-place that in the US they would use something as simple and straightforward as international electrical measurement units. As there seems to be no place for anything sensible like the metric system in the ex-colonies, I hereby propose the immediate adoption...

  • Post in thread: Victron Shunt Art ;)

    Considering the amount of absurdities I keep seeing in galleries being passed off as "art", I thought I'd do my own. Kidding aside, the "trends" section of the SmartShunt allows for some rather good looking and interesting graphs. Please post your own if you have nice ones. A cloudy day...
  • Post in thread: Best way to run AC power 500 ft from array to cabin

    OK, you can tell me to go take a hike, but I honestly think that the strategy that needs revising is the energy usage. What you're planning seems - to me - utterly ludicrous. I have a 70 sqm. house. Middle of nowhere. I have a fridge, a washing machine, computers... everything. I have 5kW of...
  • Post in thread: Best Invention in the last 100 years that you use a lot

    The Leatherman wave ;·) Well, I use it a lot anyway :·) -
  • Post in thread: Flow of electric

    Heat by friction is also interesting. Maybe move to Humor section? ;·) -
  • Post in thread: Global warming is real, why only in USA is there denial ?

    We're smack in the middle of the last ice age, actually. We might be towards the end of an interglacial period, though.
  • Post in thread: measurement unit consensus.

    Well, I guess Liberia and Burma don't :·)
  • Post in thread: Dunning Kruger effect

    What is worse is the outlook. Nowadays, smart people tend to not have children :·/

    Make it easy for cats to get to the top. -
  • Post in thread: Are we all getting GRADE B cells??

    The Standard Amy Wan (Shenzhen Luyuan) Spiel on cell grades goes like: About the 280AH, we have two grades to choose from (both are the new version LF280K, brand new): Grade A: fully matched, with the test data from the original factory. Its price has risen a lot, the newest price is $190/pcs...
  • Post in thread: What are our reasons for going over to solar power?

    I wrote a cilly piece on that some ten years ago, actually ;·) It already is in most of Europe, and people still use their cars quite voluntarily :·) Actually, the reason I use solar power for my electricity is, I have no alternative. No grid here. Up to about a year ago, I had grid, and I...
  • Post in thread: Auto Start unreliable

    OK, I understand I don't understand ;·) you situation - I live in a much milder climate and an ocean away - but (just an idea) wouldn't it be a lot simpler to drain the pipes and let the house get cold than having to deal with an unattended generator? -

    Chat on Alibaba is probably the best option. Try https://szluyuan.en.alibaba.com and use Chat Now. -
  • Post in thread: For the best connection I solder, do you? Why not?

    I guess in the end the idea is, whether you solder or you crimp, don't do it badly :)
  • Post in thread: Battery noise question - where to place battery

    I keep my (Pylontech) batteries inside. They make no noise. I keep my inverter in a "cupboard" outside, because of the noise. I can barely hear it. LFP batteries, you can discharge them below freezing, but you really should not charge them at those temperatures. -
  • Post in thread: I'm worried now

    Well, we don't really know, do we? And obviously, it depends on how you use them. If you're like me, draw very little, charge conservatively, use less than 40% of capacity at worst... etc... my Victron shunt reports 12 total charge cycles in 9 months. But even if it is 10 years. Your cells are...

  • Post in thread: Cheapest solar setup to heat desperate pensioners for 6 hours a day at 37w?

    This would have to be researched and tested, but maybe... They sell 12V electric blankets. They also seem to use ~40W - but not all the time, they have a thermostat. So maybe 25Wh? Which would be 2Ah at 12V? When I say it has to be tested... :·) If you go to a wrecker's yard, and explain the...

  • Post in thread: Fake News?

    I'm afraid I might have some bad news for extra-terrestrial companion-seekers. Are you familiar with the galactic "you are here" maps for hitchiking our Spiral? Well, they look something like... So, even in the unlikely event that faster-than-light travel was feasible... no respectable alien...
  • Post in thread: EG4 life power 48v voltage at 100%

    According to this chart, 54V is ~99%. Not too bad. Actually, according to some theories (which I instinctively tend to believe), best for longevity. -
  • Post in thread: Cheapest solar setup to heat desperate pensioners for 6 hours a day at 37w?

    ... and not getting any decent heat from them :·/ To heat any living space you need a lot more heat than that, come on. Even if you have it under your chair, it's placebo at best. -
  • Post in thread: OP flag plugin

    A suggestion more than a complaint... even though I do find it slightly annoying having to scroll up and down to check who the OP actually was - I don't have much of a photographic memory, and not many people bother with avatars anyway ;·) There is a Xenforo plugin that will highlight the OP in...
  • Post in thread: Please Needing Help Quick

    That sounds like what my AIO used to do when I tried to charge with a non-inverter generator. It would sync the phase, charge for a second or two, then the phase would go out of sync, it would click, stop charging, re-sync, and so on (and on). With the inverter generator it doesn't do that, the...
  • Post in thread: 8 EVE cells from Luyuan

    I just got my 8 280Ah cells from Shenzhen Luyuan (Amy Wan). Grade A-. They took 83 days from order to door. And the parcel people made a mess so I had to go and pick them up (60 km. from here) twice. But, apart from that, I'm really quite happy... so far. The packing was really good. Made to...

    Well, if you like steampunk, you could get "creative" :)
  • Post in thread: Did I blow it?

    You plugged your what into what? What part (cable) of the inverter did you plug into what sort of outlet? -
  • Post in thread: Best way to run AC power 500 ft from array to cabin

    I guess the main reason why people are suggesting to transfer high-voltage DC is, it's a lot easier. By stringing enough panels in series you can make pretty much any voltage - without the need for transformers. And if you use one or more SCCs that can handle that voltage... [EDIT] Say you...
