in order for the GTI to connect to a local grid you have to turn off anti-islanding.

Hi Roger,

respect, but I beg to differ on this one, Sunny Boys and Windy Boys will connect just fine, I've done it with several for over a year, when I finally got around to getting the 'Grid Guard' code to turn it off. Admittedly they do tend to drop out if you put on a heavy inductive load but they work just fine, even with another brand of modified sine wave inverter supplying the grid. I've done it using both a Trace and an SI6.OH. Think Bautche did the same too with his set up (SI 5048 and SB3800) until he got the code, which I believe they now charge for  Shocked Not an expert by any means but I believe that turning it off just widens all the parameters, perhaps it has something to do with the earthing. The sparky that wired our new house said that "you have the best earth I've ever seen", whatever that was supposed to mean  facepalm

Cheers, Paul

I have no idea about  that "anti-islanding" mode settings   ,but  am   more than 100 % sure a Sunny Boy will not produce anything / has to shut down ,   when there is a power-cut on the  main grid , whatever mode you have set

Low or no impedance between point of use and supply earth.
It reduces delay and overshoot of your protective switchgear.

I've also done it with a Trace.

...and the answer was ....   the battery  is not the question

the question should be  other way round !    So  what size of GTI to connect to a battery !

I had exactly the same comment regarding the earth from a contract sparky wiring up our extension. He was unable/unwilling to further elaborate so, not knowing whether to be elated or despondent at this revelation, I promptly forgot about it.
Thanks for shedding a bit more light on it Scruff.
Excuse the idiot's question but - is this likely related to simply off-grid installations or has it something to do with Wind Turbine earthing?
