Thanks to the contributions here I managed to install a gti system last January and been running great.

 

I have 3 330w panels wired in parallel to a cheap 1000w inverter. I have two of these setups.

 

These are wired to the house consumer unit.

 

 I just seen on facebook that our area “udon Thani” have started to replace the disc meter to digital. 
 

The question I have is can I install a no export limit. My inverters have no option to fit this.
 

Maybe just keep the setup as is and look at a longer payback period. 

 

or look into a hybrid inverter

 

looking for suggestions really 

There's no easy way to add a limiter to an existing GTI system, either replace your GTI with a unit that has a limiter (there are some low-cost units available) or DIY some way of using/dumping excess energy.

 

Hybrids work well but you have the additional cost of the energy storage system (batteries).

 

Do be aware that there have been (unconfirmed) reports of electronic meters counting UP if a user should export. Obviously, this is not something you want to happen.
