I've not actually done any measurements of consumption but: - Our double gates have 2 x 300W actuators (we have heavy swing gates). A full open the close cycle takes about 60 seconds (30 each way) - this I did measure. So, one open close cycle uses up to 2 x 300 x 60/3600 watt hours. About 10 Watt hours or 0.010kWh At 5 Baht a unit that's about 0.05 Baht per open/close cycle. So, to achieve 1000 Baht per month that would need the gates to operate about 666 times per day!! There are only 1,440 minutes per day, if they need to operate that often you might as well leave them open. ** This assumes I've done my sums correctly of course. No warranty implied or inferred. ** I'm also assuming that the idle power of the controller is negligeable compared with the operating power of the gate actuators.

Sounds like a dry bearing to me. Still under warranty??

But would you actually admit to being either??? Case proven m'lud. Burn the witch!!

I'm not a great lover of the "universal" outlets anyway. The interesting shape of the contacts combined with the "monkey-metal" they're often made from ensures that, particularly after UK plug has been used, the contact can be somewhat iffy. If you really need to use UK plugs order a pukka 13A one from Malaysia or Singapore, or do as we did, and get the family to bring one with them, stick a Thai plug on it and you're gold. Using an actual UK strip also mitigates any polarity issues.

I reckon someone could do with a poke in the groyne

Rule #2: Make sure that your backup will actually restore! There's only one thing worse than having no backup, and that's having a backup that won't restore (ask me how I know)

You will need to replace the main switch with a suitably rated 2-pole MCB for over-current protection, Thailand has no DNO fuses. You could then put that switch in a small DIN box and use it as an isolator. You need to wire MEN as per the Thai requirements routing the incoming neutral via the earth bar, so your MEN link actually needs to be the same size as your incoming cables. I've never seen a Thai domestic sparks with a megger, they do tend to rely on the "bang-test" (if it doesn't go bang, all is good). Look at the routing of the incoming neutral: -

So, you've signed all the necessary agreements etc? Or do you mean you have an electronic meter that records export but you have no agreement in place? Which is effectively the same as not having an export meter. It may still take months to sort out all the paperwork and inspections 😞 With no agreement all bets are off as to what PEA do. But as with all things Thai it's up2u. EDIT I would have a word with your contractor to see exactly what they've signed you up for, simply "registering" your solar isn't that same as getting on the feed-in tariff.
