Guys - I am sure this has been answered but I am not clear.
I have been advised by two installers that if I have a 4kw system ie 16x250w panels I don't need a DNO providing the inverter is not capable of or is limited to 3.5kw as can be done on the SunnyBoy. He said he installs all systems like this and has never had a problem.
However, another installer is telling me that I can only have 3.66kw on the roof. I want to make a decision today all 3 installers say they can meet the deadline.
The reason I would like the 4kw is it will produce more energy on cloudier days and when the panels get older it will perform better even with the losses.
Advice will be greatly recieved or if somebody could point me in the direction of any documents on the Web I don't want it to be a Grey area black or white.
Cheers
