1 or 3 inverters for 10kWp 3 phase installation ?

[kvnrub]

I have had 3 different installers come and survey my site for a potential 10kWp 3 phase installation and have had different options put to me in respect of inverters.

Two companies have quoted for  3 x 3300 inverters ( one for each phase) whilst the other has quoted using a 10000 inverter . Are both options acceptable for G83/1 conformity and access to the FIT's ? If so which is the better route to choose ?

Won't the 10kW one
just cook itself quicker?

no real experience here, but from googling, a large 3 phase inverter is cheaper than 3 smaller ones

I found a 17.6kw 3 phase one for just under £4,000+vat.... which was a lot less than when I was looking at individual inverters for each phase....

3 inverters is what I would reccommend, smaller cables, less heat (probably), more flexibility, and if one of them goes wrong in five years time it will cost a lot less to replace. just my opinion though.
