  1. Much depends upon the maximum input voltage of your inverter. If it allows you to have all the panels in parallel then shading of one set or the other won't matter (but you will need to have individual fuses for each panel with 5 in parallel). If you are going to have series strings then a separate inverter for each string would be wise. Also note that you are limited to about 3.5kW (16A) with a Thai outlet so separate inverters could be the way to go anyway to avoid issues with the el-cheapo outlets which tend to get used here. Do you have any particular inverter in mind?
  2. Your problem is those "universal" outlets. The UK has the L&N transposed with respect to Thailand, so whichever way round you wire it will be "wrong" for one or other. Hook up your new plug so that it's "right" for the plugs you use most with the extension. Note that Thailand should be "Live on the Left" when you look into the outlet with earth at the top. It's not totally clear but is your new plug actually correct? (I also see rather more bare-copper than I'd like) Most (all) modern appliances don't really care about L-N polarity but it's best to be correct.
  3. Yeah that works, the commercial hold-down systems are intended to resist a decent blow. Of course, the hold-down rails need to be well attached to your structure. Check out the fixing requirements of your chosen system.
  4. You will definitely need your panel support fixed to the building structure; 3 panels would be about 6m2 of surface area generating lift in a bit of a blow. How are you going to fix the panels to your support?
  5. This is the internet, I never fail to be surprised what some people believe. Some people even think the earth is round
  6. @TronxII I think we can agree that the mating surfaces must be clean and oxide-free before making the connection. If one chooses to add anything into the mix to (possibly) ensure the connection stays that way it's entirely up to you.
  7. Mock Franglais suggesting that maybe the person spotted vaping was himself. As others have said, no worries for returning, the police wouldn't be remotely interested. To be honest, I'd be more concerned that you look the right way when crossing the road (and remember that motorcycles can come from unexpected directions).
  8. You can't compete with the "Real" worst jokes thread ????
  9. Grid-tie, off-grid or hybrid? Lots of choice of all flavours. The low-cost stuff from Suoer and PowMr seems to get decent feedback, but if it fails buy a new one.
  10. How (which software) were you getting your 100 channels? I made the mistake of buying an Android TV, I assumed (bad move) that it would be like a 50" smart-phone. Wrong. Next time, dumb TV and Android box or ChromeCast and cast from my phone which just works.
  11. Damn you autocorrect
  12. My understanding is that most of it gets squeezed out where there is going to be metal-to metal contact anyway, but it's entirely up to you if you use it or not. It's recommended by many (but not all) in the wider battery community where you have dissimilar metals (aluminium battery terminals and copper bus bars). Note that the commercial pack manufacturers use laser-welded connections so these issues don't arise. EDIT Apparently the metallic content is actually zinc not aluminium.
  13. Yup, you clean the terminals first, apply the goop, then assemble. The goop has aluminium dust which fills any microscopic gaps with a conductive material whilst the greasy carrier keeps out the damp and air. You really only need a smear, one tube should last a lifetime. So, you have to use it during the assembly process or if you strip your pack to re-configure or add cells etc.
  14. This ^^^ t-shirt I have, with my handwriting I should have been a doctor I make ours from decent copier paper, laser (ink jet works too of course) printed as required, trimmed to size then stuck on with glue-stick. Cheap and easily customised / changed (and they don't drop off).
  15. And for an annual perspective (thanks @KhunLA for the idea). Averaged over the year we generated 84.46% of our electricity needs from fusion power. EDIT Over the year we totalled 10,897kWh from solar, at 4.5 Baht per kWh that's 49,000 Baht I've not paid to PEA. Madam is happy ???? EDIT 2 I've not updated my ROI spreadsheet for a while so I got a nice surprise when I punched in the numbers to date. We are just under a year from break-even and truly free energy ????
  16. Happy New Year everyone! Let's see what 2023 has in store. Meanwhile, the generation numbers for December are in. Over the past week or so we've been generating more than we've used (cool weather = no A/C and it's been nice and sunny) so our "Monthly Energy" has been on a downwards trend. Must ensure we don't actually go negative! Blue = Total consumption Green = Solar generation Red = PEA usage.
  17. I doubt there would be any issue using a common rod if the SPDs are close together physically. Our DC and AC SPDs share the car port metalwork as a common grounding point. The car port does have a rod too, but the metalwork alone actually tests better than the rod! But the rod is required to be "to code".
