Is there a difference between EU and US model in choosing a Deye inverter. Is it ok to use the Deye Inverter EU variant if the connections to the Grid were L1 and L2?

Grounding may be an issue. USA version has L1 and L2 at 120v to ground. In EU version, one of the lines is 0v to ground.

At least in my 3-phase EU model you can choose between 50/60Hz.
If your looking to use it in the Philippines you would need the EU version, the US version uses split phase 120v whereas the EU version is single phase 220v which is the typical grid output there.

At first it difference is the Voltage, EU version have 2 voltage, single phase and 3 phase, the US version only split phase.
The second is the certificate, EU model don;t have the US version certificate.
But in one situation you can do this, Deye EU 3 Phase HV hybrid inverter model can setting to US 3 phase 220V.
We have find this situation and testing it's ok, the only problem is it don't have certificate when you connect the grid and resell the electricity.

No its not.
We have hot wire
We have neutrale wire .
We have ground wire what it in the house on earth pin.
We do not use like usa a ground from the main power line.
Comparing American 240VAC equipment to European 230VAC
This is more a question for curiosity, as I don't have a 240 volt appliance nor do I plan on visiting Europe. As far as I have been able to tell, much of Europe uses the CEE 7 standard for household

We have 1 fase or 3 fase line.
All house have grid line of 3 fase .
So all house have 400volts.
400 volt are use for cooking and or ground heat/cool pomp heating systeem.
This confuses me here in Thailand for all intense purposes the electrical system is European (earth/neutral bond is considered an extremely dangerous practice) yet they state the earth should be bonded to neutral same as the US I've come across a few family installations where it's bonded and the safety devices won't work so the bond has had to be removed.No its not.

What do I do for my inspection? Follow the government requirements and bond with the possiblity it doesn't work or not bond?
I guess I'll find out when I wire my system.

It depends on what the utility provides to the customer.
In North America the utility company provides only the current carrying conductors. (No ground)
We make the N/G bond at the first disconnect and our grounding system begins there.
In some European countries the utility makes the N/G bond and provides the customer with a ground (PE) conductor. In that case, you should not make a second N/G bond.

you'll find this a very interesting topic...
this user converted a 16 KW deye to split phase

essentially the US split phase is what we would can single phase, where "our" + would be L1 and our "-" would be L2 ground would then go to ground..

Unboxing of Deye 16K Hybrid Inverter
Hi, Here's a pics of a well built Deye 16K Single phase version of their latest Hybrid Inverter, a distance cousin of Sol-Ark's 15K. Just one 1KW more ???? The hardware build is pretty impressive. It have two built in 200A DC circuit breaker for two sets 1 AWG battery M8 input connectors...

I run single phase European Growatts, for my split-phase system.
It was (and I believe, still is) the best option available.
Never have to worry about leg imbalance.

So where at the first disconnect should the bond be made I'm hoping after the main rccb? here they only supply live and neutral I'm guessing that's why the regs state a bond should be in place the only thing that worries me is the occasional time the engineers decide to swap the conductors likely a live/earth bond would trip the rccb. I'll start drawing up a circuit design soon when I have some spare time I have some questions about ground rod placement where bonded rebar and ground source stainless pipes will be used.

Anywhere in the enclosure that the first means of disconnect is located.
Should be before any GFCI/RCD, or they wouldn't function correctly.
So would this trip if a live/earth bond happened?
Edit: thinking about it even if it did trip the live would still be bonded to earth

"Live", describes the conductor that is not bonded.
If one of the conductors provided by the utility is already bonded. You will need to bond the same one.
Sorry your not understanding how backwards Thailand's safety is, I could bond one conductor then if a drunk crashes into a power pole and blows the transformer that feeds our village it's a 50/50 chance whether that bonded conductor gets reconnected or the unbonded one.
Edit: just for clarification the phases have been swapped 3 times in the past 5 years

Its really save .
We use special systeem.
That compleet shutdown on a drop of water.
Aardlekschakelaar - Wikipedia
Use Google Translate how this systeem works.
The hole house is protect with this systeem.
And it do not need earth wire to earth .
This is what I currently have in place without a n/g bond but once my solar is installed I'll be forced to fit a n/g bond due to egat(Thai Poco) regulations. I could be worried about something I can easily rectify after the inspection by ripping out the bond.Its really save .

I see. That could be very frustrating.
I guess that you should keep some slack in the wires. In case you have to switch them from time to time.
