Yes, i prefer to think of it this way, my Seal would have cost me a further 49.18% if bought in the U.K. and no doubt the cheapest electricity plan there couldn’t compete with my TOU meter ( 2.6 baht per unit ) here.

How did you get a TOU Tarif of 2.6 baht

Mine is 3.5 baht + ft

Sorry for the late reply. There were busy days with the 3 kids.

Today there was a sunny day after all. Perfect for observing if the changes of the inverter settings made a difference.

And what can I say?

The inverter is still restarting when hitting 5.8kw output.

A) it might not be the export Setting in my case

B) IT MIGHT not be the possibly overheating of the inverter as I upgraded a stronger fan for cooling.

So it must be too many panels output for the 6kw rated on grid inverter.

Thank you for All the advice and Support. I really appreciate your Knowledge And ideas.

I would buy a plug in voltmeter on Lazada and plug it in a socket and see how high it gets before it resets.  Crossy will probably know what the permitted voltage is, probably 253v or something like that, if it's hitting that then shutting off you will know it is a weak grid.

 

Alternatively, try turning on a few heavy loads (air cons on cold etc) and see if it still happens, if it doesn't the problem is a weak grid. You could try removing a few panels until it doesn't happen (or enjoy the cool air).

 

I have 2 grid-tied inverters and 2 of mine will do the same, I've cadenced the voltages so they go off in succession until they are happy.

The export to grid is turned on but limited to 2500 Watt.

So there is always some demand.

Should I put that figure up?

What does the fault history show?

It shows no fault.

I just resetted the inverter the day before. It might be deleted.

Let's wait for a sunny day and check again.

Most grid-tied inverters will ramp up their output until they either reach the rated capacity and stay nailed close to that

 

or

 

Ramp up their output voltage until they hit the maximum voltage allowed and then error and restart.

 

I suspect yours is the latter.  This happens on a weak grid connection because there is insufficient local demand on your side of the transformer.  

Just adding some background info here:

I guess the Solar panels are already oversized for the inverter.

?

It's string 1 8x450w = 3600w

      String 2 6x550 = 3300 w

I used to use only string 1 for quite some time and I don't remember having had these issues.

Now with string 2 working that's when the issues started to occur.

The inverter now also gets very hot.

I added acrive cooling but arrow d midday tye inveter would hit 60° CELSIUS on a sunny day for sure.

That's for your helpful comments JB:

The inverter indeed never goes over its rated AC output. that's true.

That might be it. Although there are some restarts when 6000w ac output is not hit.

The thing avoit the voltage is what I still don't know how to figure out.

Above I posted some screenshot of the 550w panels including some max voltage numbers.

How to calculate it?

Could high voltage surges cause some trouble here?

We have got an INVT ongrid inverter (invt mg  6ktl-2m) and sincevwe upgraded more panels it restarts frequently when the inverter is maxing out about midday.

It also gets very hot although we added a bit fan for active cooling.

Is there is too much output from all the panels for the inveter now?

Have a look - advice very much appreciated.

The setup as follows:

String 1: 8x 450w.mono panels

String 2: 6x 550w mono panels

How is it going on?

How much is the cost to get a already installed solar farm registered with PEA/MEA 

(Let's assume 5kw 1 phase)

Any "guesstimates"?

I just have started the PEA Registration Process for my new System, my Installer is doing all. Costs are 20.000 THB and will take around 3-4 month time.

Would you tell more about it?

I think there are many members here who are keenly interested in hearing your Story!

Why not bying solar farm stocks?

There are some German solar-farmers stocks (that I own)

The operate solar farms in different countries and they have a profitable business model. Positive cash flow. Paying dividends for years. 

Downside is, this business Modell is very capital intensive and has a long payback period. So rising interest rates will do no good over the long run.

But who knows what the big thinkers will do with us and our money supply next. 

What I should to do, I assume, is checking if my solar farm checks all the requirements from the PEA.

Thanks to crossy I checked the inverter list already. And my inverter is on that list.

The engineer clearly stated that for 1 Phase house connections there is a limit of 5000w per meter.

I got 8x 450w panels at the moment and would upgrade to 11x 450w panels = 4950w before applying.

What about safety features of the solar farm? Is there a handbook with all.the requirements from.the PEA/MEA?

Any advice?

In my case they send out a ordinary PEA member the next day to check the circumstance.

 Maybe its time to stop exporting for a few days?

Why are there are 2 different displayed number on the meter?

What does it mean?

Actually there is a CT installed. So it's possible to turn off export to grid.

There are things I don't like about it. So I would only deactive export if that is really necessary.

1) the Inverter restarts often if there is not much consumption.

1 aircon and 2 fridges are running 24/7 and that is about 300 watts/hour. Which is not enough from preventing the inverter from.restarting frequently especially in early morning and late eveni hours.

I think it's not good for longevity of the inverter either.

2) this point is my observation. Take it as speculation as you like.

when power output is at a certain Level,it seems to take a while for the inverter to level.up.the needed output.

This means more import from the grid overall

Actually I think it's it is a fact that everyone has to admit that the energy consumption of the world is rising.

History shows that energy consumption is always rising.

And if there is a new energy source found,it never substituted another energy source. No, it adds up to the other sources that are in place.

It happend with wood>coal>oil>gas> uranium> etc pp

My point is, you never know what the big thinkers are up to. Especially not in Thailand.

But it's an undeniable fact that Thailand will need solar power in the future.

More so as the demonestic gas reserves in place have peaked already and its output is declining.

There is more and more demand for LNG bow which is very pricey.

(Thailand is heavily depended on fas for energy gernation)

@eddysaccwhich inverter do you have?

I have got a 6kw inverter.

This one.

The PEA found out that my meter is spinning backward.

So they send some ordinary staff out to my place to check.

I let him inspect my property, and he finds the solar panels installed on the roof.

So he is saying that tomorrow some engineer will give you a call and check your place again. 

I'm asking if there is a problem. He is replying, "Don't worry.

This was one week ago, and nothing has happened so far.

Opinions, please. How will this play out, and should I do anything ?

I got a position consumption on the meter about 100 units every month.

It is an undeniable fact that - in Thailand - the Mitsubishi brand is regarded as an unpopular choice in the second-hand pick-up truck market.

Also, from a logistical viewpoint, you might be better off finding a buyer in your neck of the woods as I am not willing going on a 8-9 hours round trip prior to settling on a price.
(I don't think you would go on a lengthy road trip showing off you truck without potential buyers.)

You have to realize that my offer includes the risk in believing and trusting your tout about your vehicle.

Based on your comments and pics I sway from my original offer and am prepared for paying THB666K for your Mitsubishi pick-up truck which is considering the reality of circumstances not a shabby offer.

I must admit your words are convincing about your view of the squint thai second hand auto market.

I will offer the again lowered price of 680k thb which is my pain threshold.

I have some more interested people recently which makes me confident that i can at least retrieve this price in a reasonable timeframe.

If you accept this in my view very good offer, i would furthermore offer you to accompany you to the Khon Kaen Office of Transportation to give you maximum security when overwriting the blue book in your name.

The new Price of the Mitsu Athlete came about 1.07 Mio thb.

There are different models of Ford wild track.

If its really a top spec model and the car does not come with hidden problems then congrats. Buy it. 

I will not let the triton go for 650k, sorry.

I would be open for negotiation in a reasonable span when you come and see the car.

You will not be disappointed.

So sorry for not replying sooner! I was busy inspecting another pick-up truck which I can get for THB600K. The vehicle's got similar specs to your truck.
Sorry for the inconvenience I may have caused.

I don't believe you would get a similar clean accident free truck like this fot 600k

May i ask you what brand and model it would be?

Not yet.

My wife got another baby last week und did not advertise.

I will reduce the car to 700k thb and i would teansfer the car to you.

The value of the car must be arround 790k referring to tanachard blue book ( without the extras like 18" mac wheels and optical improvements

Its really a great car.
