    Splendid, welcome to the club. Best angle for the panels is about 25 degrees facing as south as possible. That Vstart is a real teaser if you are unaware of it. Assume you downloaded the manual and I hear you bought a copy of my book, thanks for the link, cheers

      It was just good luck that you mentioned the Vstart in another video that I happened upon last night! Otherwise I might have spent the morning scratching my head! The manual says to leave Vstart as it is, surely it is better to have the relays working with the lowest V, as that would give a low W/A as well? Or maybe I should put my neck back in. I can get most of the panels 10 or 12 in a string to face due south at 25 deg, but they will be obscured by my house until noonish. Once I had let go of the concept of a return on investment anything was possible, if it is an experiment then it can't fail. I have the constraints that I have in terms of siting, and I have the skills that I have, so I'll do what I can. Thanks!

      Hi Andy
      I am thinking about getting these panels up, I think 25 degrees is the same angle as my garage roof, so it would match well if the panels were adjacent.
      But it got me thinking, are all the roof mounted ones a bit of a compromise? In as far as they are at whatever alignment and angle that the roof has?

      @@bootsowen Owen, yes it's all a bit hit and miss. The shallow angle might not be correct for winter sun but it fine for what I call ambient light, meaning light reflected through light cloud. Just do you best for the position and don't get hung up on rabbit hole details, cheers

    Hi is the system still going strong and have you had any problems with it ? And could you do a video of the ac side of the system and how it’s connected to the main distribution board ?

    • @bootsowen
      @bootsowen  2 роки тому

      The system works without issues in full sun or even on pretty shady days. On the ac side you wire an isolation switch then directly into a circuit in accordance with the regulations in your region. I have no idea where you are so I can’t help more.

    I'm going down the same rabbit hole,, But if you read the manual first, you would know you have to feed it DC to come on and program anything.

      Hi, at this point I didn't know anything about these things, but have a look at my future videos on my solar playlist. I have 4 inverters working now. This one and 3 bought as scrap that needed various repairs. Thanks

    Can you draw a basic bigclive drawing of what's going on in that complete system please Mr.B. ?

    • @bootsowen
      @bootsowen  3 роки тому +2

      You won't need it! the solar panels are connected to the inverter, the inverter turns DC into AC electricity to exactly match the mains and pipes what the panels generate to the grid through a plug. It shouldn't be a plug, but I was just testing it!. Andy is better placed to describe what is going on inside the inverter. But my understanding is that it just chops up the DC into up and down pulses of AC. How it does it gets technical quite quickly and is beyond me, but there is 2 computers in that inverter box. Let me know if that is not enough for you, I can make a video, but I have a feeling that Andy has already made it! I will post a video when I get the panels mounted and it is a sunny day!

    È possibile alimentare questo inverter con batterie invece dei pannelli solari?

    • @bootsowen
      @bootsowen  7 місяців тому

      Yes, if you can get the dc voltage over Vstart of 120vdc. but it will try to feed the grid with the maximum that the battery can give. so I'm not sure why?

  • @t4yjt

    I have the same inverter , or you have to link the v1 and v2 , as I have 40v on v2 with none plugged in, assuming the amps to high on the v1

    • @t4yjt
      @t4yjt 2 роки тому

      Sorry yes the reason you have volts on the other string is , when you only use 2 of the 4 DC inputs you have to link them out so the inverter Equals out the amps coming in

      The aurora in the video is a grid tied inverter, it will only work when the grid is present. If there is surplus electricity it will go into the grid. your meter may or may not notice this. I have made other videos about this.

    The AC is an output - it should draw no power from the AC mains as it is designed to take a DC input and output AC

    • @bootsowen
      @bootsowen  2 роки тому

      The ac side is interesting. The inverter has to detect the dc first before it fires up. Then it looks for ac and checks voltage and frequency. So initially the is an input but only for detection. I imagine that various inverters have different startup regimes.

    Bargain. I only use our solar array for low voltage (12V) battery charging and powering our greenhouse/ polytunnel's grow LEDS. Obviously an inverter is at hand if mains are required.

    • @bootsowen

      I am thinking about batteries too, but this is a good start, with a reasonable investment. Batteries would make it independent if the grid goes, but candles and firewood have worked for me so far, with the car battery to charge phones. The only thing that would be useful if the grid goes is to keep the fridge going. But in 10 years in this house the 5 or so outages weren't long enough to let the freezer thaw.

      @@bootsowen Ah we are in the middle of nowhere in Scotland. Same on the fridge front . We have a log burner with plenty fire wood and a 1200 litre kero tank for the CH which needs powered. A wee petrol genie which could run all the essentials and a 5kW red diesel shop genie (1200 litre tank again) for the tools which would happily run the washy machine if required.
      As obvious though the solar is the best redundant system. You could start picking up car batteries, even old and recondition them. 18 in series ideally 600 amp gives you in excess of 130Kw at full charge.
