Which will do sweet f/a.

We've already been through this so no, what is shown there is kW...units are kWh....... 6.9kW is instantaneous

Yes, I would imagine that would be a good estimate, BUT, that is at peak time (instantaneous). To give you an example, my system is 22 panels @250W per panel. ( installed back in 2016). Peak (5000W) usually occurs in January around 11am. Total for the day can be as much as 30 kWh, winter maybe around 22-25. The main difference from you to me would be in consumption. Where I might use 10kWh a day, yours seems a lot more running you RAC's. There is another difference that Thai PEA have so far to think about is, we get paid for any feedback to the grid. When first installed, rate was around 6c/unit....then it crept up slowly each financial year to around 10c/unit before declining again down to the 6c mark. Lucky for me though it started again to increase (political pressure I imagine) where it now stands at around 13.5c/unit (for Qld). Poor buggers in Vic get around 3c/unit I believe. Be-all end-all, mine paid for itself in around 4 years. (with gov subsidies of more than 60%) I also run a storage hot water system(250 litres) which comes off the inverter before feedback. A timer switches it off the grid between 4pm and 9am next day to ensure that 99% of the time(not raining) it runs off my generated power. So in all, my HW is essentially free, and average payment for feedback per 3 month period is around $150 to $200. Until Thai PEA do similar, you will never be in that boat though. I'm waiting to see if they even move a small amount in that direction and I'll be putting solar array on the house in Khon Kaen province.

What I meant was you were showing readings of 19W from the array, 16W used and 3 W as feedback. Although these figures add up, it also shows generated power at 6.9kW and that is labelled as "todays generated power" .......generated power over time (today) would be in kWh , not kW. No idea what this Pac is supposed to represent, can only guess at it being instantaneous power. In all though I can see where you are consuming bucket loads of power when you say only one of your RAC's is 17,000BTU (around 5kW) What is the actual size of your array? You say the inverter is around 3.3kW but without knowing the panel size, it's really irrelevant as to power being generated. Asked before but seems to have been lost. If the Pac is indeed instantaneous power, it does seem a bit low if you had a 3kW array.

Figures you supplied don't make any sense and conflicting both with info you have already supplied and the readout, such as it is.

More than likely cheaper as they make/sell many more. Bullshit on efficiency is just that, it's again, more than likely around 7w coil(inductive at that) , so if you're going to start sprooking "efficiency" , it would be almost impossible to detect let alone justify.

Without actually being there and seeing for myself, difficult to say. However, something is not right, that's for certain. If the array is around the 3kw mark you should be getting more than 3 units a day...one reading you show goes to 7 which is closer but no prizes...should be more like 10. It's not rocket science...if you get 3kw generated for 1 hour that's 3 units (3kw x 1 hour = 3kwh or 3 units)...so even at 5 hours a day you could expect to see 15 units total, not 3. So either the array or the inverter is dodgy, or the app giving incorrect data (unlikely but possible) Can you read directly from the inverter unit, does it have a display of total readout per day/week/month? Might be time to get them back to check the system if it's still warranty. If not, get another mob to check it. As for the system itself, there should be complete details of the actual array and inverter size written on the install document rather than continually guessing what is what.

Open a new discussion, I'll bet you get a gazillion replies and just as many variations on spelling.

So you are using 20 units a day from PEA and 3 units from your solar...something wrong there. As Crossy quoted, should be higher than 3. I get 30 units a day from a 5kw system(summer) and around 20 in winter. Seems your are facing the correct direction and angle should be somewhere between 15 to 20 degrees. No shading at any time during the day..??

Do you have any details on size of the system? You must really hammer the air conditioner if that is a monthly account WITH a solar install.

Better get their finger out and make some moves, 2024 is already here and will be half gone before they stop talking about it and do something.

I seriously doubt that......sounds very much like an across the counter quote on pub night.

The outlet is not controlled via any switch, so in theory, doesn't make any difference. The "tester" is a two bob trinket, while showing active is present in the neutral pin, it does not give any affirmative indication on earth. One illustrated example shows one thing for open ground while another shows it as different indication. I'd be more concerned about the voltage levels shown.

Me too......in the right environment. Simple correctly fitted saddle does the job.

Procedure we would normally use is a j-box with appropriate current handling capability. Earth frame of any metal enclosure. Normally not a problem with the Clipsal giant plastic j-box. Failing that, do away with your fixed screwed terminal block and solder the fixed wiring and oven lead tails together, add appropriate insulated connector (would be unavailable in Thailand) so tape over. One may find some somewhere but I gave up looking a few years back and took 200 of each (single and double screw connector) with me from Aus. Note:- connector shown has ability to terminate 3 x 6mm2 cables in each connector.

One could go that way but the cost difference is massive.

I've seen these run directly from a rooftop solar panel as well. No inverter, connect direct to the dc from the panel. A 250 litre would keep 2 people happy for days.

....and after that..???......... what happens.....don't see why Thai should have to pay for some cheap charlie's insurance. As usual, the devil is in the detail. I always arrange travel insurance for both my wife (even though she is Thai) and myself when coming back to Thailand, part of the cost of the trip. Combo insurance is around 50% extra for both of us compared to just one. (me) In this instance I see the latest fees are around AUD$350 for the 30 days away from Aus. for both of us combined. No way top of the cover range but it does cover basic accident, hospitals etc when we are there up to around $5 mil I think. I'm just curious why it never crossed the minds of the government to make travel insurance compulsory for entry to Thailand.

That will get rid of you...not the termites. They move under cover and under ground. One way to stop them is injecting around any wall that abuts with exterior. We have been setting outside traps, 100mm downpipe around 300mm long buried in the ground with "inviting" pieces of pine inside. Top is capped with removable cap so one can inspect from time to time. When they appear, load baits down inside the tube. They take back to their main nest and kill the queen ant. Apparently queen can live for more than 10 years otherwise. Baits are in the form of a powder one mixes with water. https://www.bunnings.com.au/superway-500g-white-ant-termite-bait_p0287717

Possibly due to their using solid rather than the more flexible, stranded conductors we use in Aus. Either way, 6mm square is the Aus standard as you say, but take a look around you at the rest of Thai wiring. I wouldn't be too quick to condem Aus regs.

6 square mm copper.

No...combo's will trip from either and usually there is a trip indicator showing whether over current or earth leakage. The earth leakage may be 30mA but the trip current would depend on many conditions including current rating and class of breaker. Still waiting for photos of sw board setup from OP to make further educated comment.

These two comments contradict each other. Are the above part of the one breaker or two independant units...?? Photos thanks. Other than that I'd say you are sufferning from effect of voltage drop and your disconnecting the earth is simply nothing to do with the situation. Get PEA to check any and all connections at the pole/meter........(twist and tape territory in Thailand..........aluminium mains capital as well) Use gas where mains cover long distances and you insist on using undersize mains as per Vdrop calculations.

I don't really see the need to run battery operated spotlights for 12 hours at a time. That would really be "some" battery, especially at 2000w as they tend to run up around 40 to 80v dc. If you need to run that amount, fit mains lights, unless of course you are out in the never-never. Other than that, probably best to go and buy a couple and try them out, navigate away from the el-cheapos naturally. You'll find most are over-rated on what they say the performance would be. Just don't expect to get what is written on the pack, either run time or life expectancy. As an added note on the latter, one used to see ridiculous claims on thousands of hours life....all been removed down under here at least...never see it on the box anymore. Always said it was crap.Maybe the LEDs would hold out but the drivers tend to shit themselves and replacing any part is not even considered anymore.

Yes, to be fair and clear in the description, earth grids are used here as well BUT not in what would be considered "standard" installations, be it domestic, commercial or industrial. Grids, as you point out, only have the one MEN connection but are largely confined to supply authority HV transformer yards. There is no need or requirement to have ground resistance included in any installation inspection etc. Bit off subject but only variation on that was the install of a lighting protection system with isolated earths at a local hospital. Interesting to note that this was 20 years ago and checking the strike counter some weeks ago has revealed a zero strike count. I think it was more related to the architect trying to score brownie points with design. I have seen/installed earth grids in coal mining situations where the ground resistance is upta crap........they are restricted to mine systems which are not connected to what is normally considered the supply authority grid, usually at punch mine with generator supply but this has more to do with coal mine strict requirements regarding any above earth voltage rise (for obvious reasons).
