DNO turning off systemsDno turning off systems

They have given us a confirmation letter for the 25 kw is acceptable

Fair enough, but there are suggestions that the DNO could subsequently ask for this system to be turned off IF they decide that the system is creating a voltage rise (it will) which the DNO decides is affecting the network.

The lenght of run back to the supply is 120 mtrs there could be volt drop on the ac side and if your concerned about that being switched off you wouldn't take on any job more than 10 kw

It doesn't work like that. Your system will produce power at a voltage that is higher than the grid voltage regardless of the volt drop on the AC side.

I am concerned about systems being switched - all sizes of systems. I think it is a ludicrous state of affairs.

I will double check with DNO but there's no way after install its being switched off they will have to upgrade the equipment after its been vandalised!!! Lol

They'll probab;y do what they do in germany - limit the export, hence SMA's article here Requirements for the PV system technology of the future and solutions by SMA

They have solutions that allow remote derating of the PV system over the grid by the germany equivalent of the DNO.

I'm sure it will come here, it's just a matter of time.
