As was to be expected, there is also an equally large discrepancy in August, this time of ~139 units between the two meter systems: import 424 units vs. 284.6 units and export 1025 units vs 886 units. The charger for the EVs shows ~261 units for this period, which this time does not quite match the export/import discrepancy values when these are added together. 278/261 In the month of July: 188/187 I won't be in Thailand for the next whole month, so only my wife will be charging her car, which she only uses for the commute to work - that's an average of ~100kWh, so the discrepancy between the export/import values should be smaller, if the assumption that this problem is related to the charger is correct. An electrician from the installation company is coming by on Saturday ...

here's a quick update on the payment of the surplus amount, I didn't address the strange meter discrepancy that is now being discussed in this thread: “Apparent discrepancy between metering systems” during our current visit. After our first unsuccessful appearance at PEA, we tried for the second time this week. This time at least we were lucky. Instead of dealing with a clueless representative, this time we were lucky enough to actually get in touch with the employee responsible, who was able to give us more reliable information. But some of this information was even more unpleasant. For example, we were told that in the event of a longer stay abroad, we would have to send an authorized representative who would have to appear every month. When my wife intervened, they at least agreed that this could be discussed in the team, whether this would be possible only every two or three months, although we came with all the necessary documents, the payment process for the first and second electricity bill could now take place, but we would not have received the money until the 16th at the earliest, i.e. ten days later. Which would then require another visit. So of course we asked for the money to be transferred to an account. Of course, we had a copy of the bank book with us, but it turned out that there was only one bank that could be used for this, namely the PEA's house bank Krungthai. So we had no choice but to march off again and reopen a bank account with Krung Thai, of all banks, just for this purpose, which from my memory is one of the worst and I therefore closed it after a short time. We then gave the PEA authority a copy of the requested new bank book for each payment in the afternoon. This had to be handwritten on each one, stating "that the account holder agrees that the amount will be transferred to this account" + signature of course ;-). The transfer itself will then take another week ...

The ABB charger TAC-W22-G5-R-C-0 was a "free" gift from BYD and to my astonishment is one of the better wallboxes, but the v2g/v2h capability is missing from this device, neither in the descriptions nor on the net can I find any reference to it.

I have to add to my three-phase ABB charger that I am not at all sure how it was actually wired, because two years ago the first charger installed was a no-name single-phase charger and this was then integrated into the solar system installation as already described. The single-phase charger was then simply replaced six months ago by the three-phase ABB charger. I have now asked the installation company to send a technician to me next month after the August electricity bill, as this is when the annual inspection should have been carried out anyway. For this helpful and comprehensible answer alone, which even my installation company still owes me, I pity again that I can only give it a single thumbs up. Full agreement but at least a clear symptom to work on now 🙂

perhaps a moderator reading this could separate this discussion thread because it has nothing to do with the actual topic and it was not my intention to steer it in that direction. Sorry about that! The report is a statistic of my three-phase ABB charger, which also supports load balancing, for our electric car. Two years ago I ordered a three-phase electricity meter for this. Then a year later a three-phase solar system was installed. The original house installation, which was still running on the old one-phase electricity meter, was also integrated, so that everything now runs on just one electricity meter and finally two months ago the switch from analog to digital electricity meter.

"Coincidentally," my ABB charger used 186.7 kWh in July, which is almost exactly the sum of the export and import discrepancy in the July electricity bill. Another „coincidence“, or are we already on the trail of the culprit?

I don't think it's a coincidence, I really didn't notice it. I had 690 export units in mind, thank you for taking the trouble to look into it more closely 😉 and for your further conclusions. I would like to give it more than a thumbs up! I'll just wait for the bill for this month and instead discuss the problem further with the installation company...

Thank you for suggesting the PEA Smart App. I had installed it before but didn’t realize its potential benefits. Upon reinstalling, I found that the app allows access to all past bills, including the one for July, issued on August 1. Future bills can also be sent via email if desired. There is really nothing negative to report about this app and all the relevant data is presented relatively well, but also less comprehensibly if you look at it in more detail. Another positive thing I noticed is that the service fee is 24.62 baht, just like the old meter. This solves at least one of our problems regarding digital access to invoices, so thank you once again for this very useful information, which we unfortunately didn't receive from the PEA during our last visit for whatever reason ... Even at first glance, I noticed that we now have a completely new problem. Strangely enough, there is a considerable discrepancy between the units used 302 shown on the bill for the month of July and what our smart logger from Huawei records (208). Then on closer inspection of the July bill, I also noticed the feed was off by 100 units, this time in my favor. Around 790 versus 699 units. I also found the first bill suspicious, which was presented to us during our last visit but we weren’t allowed to photograph. My rough calculations suggested a payout of around 1000 Baht, but the bill showed only about 650 Baht. This bill combined the last days of May, when the new digital meter was installed, with June, and I didn’t want to dispute it. For the July bill, I expected a payout between 500-700 Baht, but it turned out to be only 357 Baht. I was confused and reached out to my PV installer via Line last night: “Dear Anan, I apologize for reaching out to you again, but I’ve noticed a significant discrepancy in the last two monthly statements from PEA. The discrepancy is between the units of electricity consumption recorded on the PEA bill and the units logged by the Huawei dongle logger. The difference is so substantial that I can’t explain it, and I doubt I’ll get satisfactory answers from PEA. Basically, in my view there are three possibilities: 1. PEA is not correctly recording the units of electricity we consume from their grid. 2. The Huawei system is not accurately recording the consumed units from the PEA grid or is misconfigured (for example, the system might prioritize feeding electricity back to the grid over meeting your household’s consumption needs first). 3. I’m making a calculation error, or PEA is using an algorithm to calculate the units that I’m not aware of.” I received an immediate response and assurance that he would look into it today, Sunday. He not only reviewed the July bill but also the combined May/June bill, created a data sheet, and advised me to present it to the PEA during our next visit, as he found both bills suspicious as well. For those unfamiliar with digital meter bills, unlike the old analog meters, the digital ones have three reading marks: P (peak), OP (off-peak), and H (holidays, i.e., weekends and public holidays). These three values add up to 302 units. The upper part of the bill strangely shows values from the old analog meter, which don’t factor into the calculation and make no sense. I hope to get a reasonable explanation for this oddity soon … Since I have no need for a TOU tariff and we charge our EVs for almost zero baht during the best daytime hours with our ABB charger, all units we draw from the PEA grid are charged at the standard electricity rate.

For once, an interim report from me too: Our local installation company, with which we are extremely satisfied, took care of the application for our 10kWp system and kept us updated on every “progress.” Their statement that it would only take 2-3 months seemed far too optimistic to me, and I was expecting a year or maybe even more, which, of course, turned out to be correct. The application was submitted by the installation company at the end of April 2023 on the relevant PEA online portal. By the end of May, this application was approved. These approvals were published in the publicly accessible area of the portal, including the address and approved capacity. According to my recollections, 2000 applications had been approved in the PEA area in the past twelve months by that time… so we are actually talking about homeopathic quantities, and most of them are 2-5 kWp systems. In February 2024, we received a message from our installation company that the digital electricity meter would be installed in April. Upon inquiry, we were assured that we could immediately export the excess electricity and that it would actually be purchased by the electricity provider. By the end of May, the new electricity meter was indeed installed. For this purpose, a total of eight people appeared in three cars, and to my further surprise, a thorough inspection of the system was completely omitted. Less surprisingly, I had to sign what felt like 100 pages again, including the contract that was already backdated to February. I pointed this out immediately, just to make it clear that I was aware of the content of this contract and smiled leniently at this inaccuracy for once. With that, the electricity export could start immediately! The next day, my wife received a call at work from an alleged employee of the PEA authority, stating that there was a problem with the electricity meter and that it needed to be replaced, which later turned out to be an obvious fraud attempt that my wife almost fell for if I hadn’t intervened energetically. However, one day before we were promised a phone call from the PEA within the next ten days to clarify the modalities of the electricity billing and the credit for the sold electricity. We waited in vain for this call for four weeks, and we didn’t receive an electricity bill either, so my wife called them herself, and we were asked to appear in person. Up to that point, I had naively assumed that the credit would be automatically transferred to us since the amount of our previous electricity bill was automatically debited from my account, the electricity provider had my account details, and there was a power of attorney to debit from there. Such a direct debit authorization is not out of the box either. But at least you can download the appropriate form, have it signed by the bank, and then submit it with the usual other useless copies of ID card, house book, etc. After my wife’s call, I began to suspect that this process could be much more complex… And my suspicions were even greatly exceeded when we then appeared at the authority! We were informed, “Dear customer, you must understand that with the contract, different payment processes are triggered” and that we have to collect any credit at the PEA ourselves every month and submit the following documents for each month: • A copy of the ID card, • A copy of the house book, • A copy of the electricity bill, • A copy of the bank book if the money is to be transferred to the account. We were also asked to buy a receipt book and issue a receipt for each individual month. When asked whether this rather cumbersome procedure could be circumvented by simply letting the credit accumulate, this was denied because the monthly credit expires after three months. At least we could find out that we could reduce these rather involuntary visits to the authority to four times a year, but still with the required stack of papers per month. This increases even more if you are not on-site yourself, which will probably be the case for us next year or at the latest in two years, then the authorized person must submit the following documents additionally for each individual month: • A power of attorney stamped with a 30 baht stamp, • A copy of the ID card and house book of the authorized person. Also, the delivery of the electricity bill and the indication of the possible credit does not seem to be a trivial matter for this authority. We pointed out that we had not received a final bill for the old meter nor any new bills. After about 5 minutes of searching through various stacks of paper, we were informed that we have a credit of about 1000 baht. However, we could not take a photo of it. I asked if these bills could be sent to us by email since we are not always on site and fear that the mail will not always reach us on time. This was at least possible, and after I gave an email address and asked for it to be properly delivered, we were told that this could only be done in the afternoon because, at the moment, for reasons I honestly didn’t quite understand, the system couldn’t do it right now. It was also noticeable that this responsible large office was staffed with at least ten employees. Half of them were obviously electricians in their work uniforms, and all made the impression that they were more twiddling their thumbs than actually working on a Friday midmorning when we were there for an hour. We had no choice but to leave this bizarre location without a payout and without an electricity bill. We, of course, waited in vain for the announced email at 2:00 p.m. Only my wife believed in it; she called again, and they said that maybe only emails ending in .com could be sent. A corresponding change, as requested, unfortunately, could not solve this problem either. We will try our luck again next month, armed with the required papers…

I completely agree with you, especially your assumption in the previous post. But if the world income principle comes into force in Thailand, then as a married person I would have to pay considerably more income tax in Thailand and my types of income would probably be taxed twice because my country's DTA does not cover this! I don't even want to talk about the bureaucratic effort and especially not about the counter calculation. What does my country give me for paying taxes and what does Thailand give me for having to pay so much tax? But as I said, I completely agree with you, that will not interest the decision-makers in Thailand at all. Cases like mine are more of anecdotal nature and are certainly already factored in and I also believe that Thailand cannot avoid this change! I don't want to waste any more words on the way it is implemented and above all how it is communicated. Apart from that, they are incompetent and can't do any better! That's why I wouldn't indulge in any more illusions. We had already decided for at least two years to leave Thailand in 2026 when my wife retires, because we had long been of the opinion that Thailand would only be suitable as a temporary residence in the winter months when we were older, but even that would only be limited by the precarious environmental conditions. Now, due to the dynamic development in tax issues, we will probably bring forward our final departure from Thailand next year...

I think you can almost completely rule out the fact that he has the so-called “Elite Visa”. The conditions of this visa do not allow this type of business activity by the Swiss or any type of work
