I (well, the MCS installer) obtained approval under G59 back in 2015 for 11.5 kW of grid connection on a single phase. 12kW of panels into two 6kW inverters. I'm in a fairly remote area. Not aware of any other solar arrays feeding into my local pole mounted transformer.
I'd now like to add more, perhaps another 4-5 kW to take it to maybe 17kW. I will be adding a battery at some stage but not right now, so for now I'd like to add to the existing grid-tied system.
I am interested to know what is the maximum power anyone has managed to get approval for on a single phase here in the UK? Is there an official limit or is it simply case by case basis? What is the theoretical maximum?
My incoming supply is 100A (judging by the size of the fuse).
Please - No advice on adding/extending FIT arrays etc. - Just need the technical limit on known actual real-life examples or specs for DNO limits for grid injection for single phase.
Thanks for looking.
