Yeah, and it rained too but solar still filled up 750 Ah battery.

This is a strange viewpoint. Please provide figures for your 20 year "payoff" (payback) time. I have an 8 kw system with batteries which recovered it's costs in five years. Also I am content in the knowledge that I am not contributing to climate change. For me, cost of instalation was almost zero. I have the skills and knowledge to do that myself. The Thai government will pay for any spare electricity you have but it's not much and can take a long time to organise.

Single phase is normal. The three phase brought to the development will be a high voltage and will be fed into a transformer for low voltage (220v) single phase for distribution to the houses. You can have three phase at a price if you really want it but it will be expensive and a three phase solar instalation also very pricey. It all depends on power usage and in particular the horsepower ratings of any motors you may want running. Above a certain size, three phase motors are smaller and more efficient than single phase. Normal domestic power is well served with single phase.

Great suff. Which Bank would that be?

On each piece of electrical equipment there is a rating plate which tells how many watts (not BTu's which is for thermal cooling requirements) that equipment uses. This rating plate is generally out of obvious site on the side or the rear of equipment. To calculate your power consumption you need to add these wattages together but only for the equipments which are likely to be running at the same time. This will give a maximun power rewquirement. Add 20% to this for a reasonable margine and for furure expansion. That is the output power you will need from your inverter. Solar panel power is usually limited to the maximum power input of the inverter (plus a derating factor of up to 20%). Since you are looking to "supplement" grid power with solar, you could split your electrical instalation into grid fed and grid/solar fed. If you want to consider battery backup, then size of the battery depends on how long you want to run for without grid power. Batteries are expensive. Repeat of Motdaen's question:- Why do you want three phase power supply?

Somethings not quite right here...........48 x 20 = 960Wh

Money

Yeah. Strange about the whole thing. Who was behind the camera? Transport laid on ready in case someone with an elite visa was on the 'plane?

Don't deceive yourself. He only wants to make himself, his family and his businesses more wealthy.

Your meter is doing what mine did after the village "expert" reconnected my power ever so slightly incorrectly. PEA would have spotted this if they had thought about it. The problem is that you have 1km of 25mm ali wire which is effectively running from the meter live to earth/neutral at your house. Taking into account the resistance of that 1km wire you are running about 4kw continuously. Meter very happy with go fast stripes. Swap live and neutral at the meter or the house isolator and all should be well. PEA were trying to help. They simply didn't first consider the obvious. I had problems explaining my similar miss-connection to them. They insisted on checking the cables artistically draped through 1km of trees from the meter to my house which, of course, were quite faultless. Like all engineers, including me sometimes, they were looking for a more interesting and complex problem.

With regard to UK banks, that goes without saying. Exchange rates with UK banks are inordinatly high whereas Thai banks are much more reasonable.

Brilliant Well done Anutin It's not true what they say about you

Sorry to jump in here. The alternative is easy and plentiful. you could get a low frequency inverter* which runs off a 48v DC supply.. Solar charge controlers and batteries to give you your 48v supply. * An inverter in this instance is a device which creates a mains AC voltage from a lower DC voltage.

I would clasify that as not a fifth way but the very first way. You have solar panels and an inverter and an ATS but that system only wortks during sunlight hours. If you want you can add charge controllers and batteries so you can have stored solar electric for night time use. All other systems are based on this and quite neatly put into a single box which is wrongly, in my opinion, called an inverter. Variations on this "inverter" are quite popular with a grid connection which does away with the ATS and can even alow feedback into the grid which PEA will stop you doing if they find out.

Seems like the brakes did not fail otherwise why the screech of tires? Modified truck well overloaded and out of control.

All this off road garbage is rarely ever done in real life. Let's see some proper off road stuff with a tonne of rice in the back and plenty of muddy potholed cart tracks to negotiate.

Nice pun.

Ha. You can say that again. It hastened my solar installation which I did within a few weeks of moving in. Because our temporary meter was 1km from the house and well beyond direct observation, uncle Tom Cobley and all were trying to "borrow" our temporary 'lectric. The temporary power and the temporary road gave us the feeling of being comfortably well away from the smoke and noise of the village.

In our village we have a dog looks just like that. His name........Covid. Poor b'gr.

I hate being a pessimist but it took us seven years to get put on residential rate. Mind you there were plenty of ready reasons for PEA to hide behind. The main one seemed to be that there was neither road nor posts for the PEA to run their cables from the last post in the village to our house. A distance of 1km. We also had to have at least 5 other houses needing supply along the 1km route. Not a problem for me because I had 8kw of off grid raw solar power which only required two sets of batteries in that time and, because of the temporary supply rate, payback was within the first 5 years. When PEA eventually ran our supply on their posts along the new government road to our house. I recovered all the old cables (2km Al 25mm²) and got a good price for some scrap and some resale to some of the villagers. It was a bit of a pain getting some of the cables out of the trees though. Trees do have a habit of inconveniently growing around them.

No but his father may have been a king? Oh bum. Someone already got there first

Some people are just born lucky.

Bigger "slices of the cake" coming for the building inspectors methinks.

A hail stone traveling at 150 mph couldn't give a toss about going through from the front or from the back. Best defence is to use my new, almost patented force field which can form a shield over each panel or the larger size which can be used to protect up to ten panels.

What type of batteries were they? Lithium? Lead acid? Primary cells?
