For this project, we had no shading issues or roof space restrictions. We decided to couple the trina 330w panels with a Fronius 3 phase 15kw inverter. This was on a new build with no roof space, so we were able to get in early and rough in all the cabling so no surface mounted conduit was seen.
With this job we were faced with not only an export limit, but also a restriction on the size of the inverter we could use at the property. With only 2 phases available we decided to use 50 enphase micro inverters to maximise the size of the system.
