I had to change it from a -ve start for to +ve start form my gen set but hat was an easy fix.
My gen set had a 3 pin GX16 aviation connector whereas the able has a 4 pin GX20 aviation connector which I had trouble sourcing. Only 3 pins are required.
My installation is also working with PV.
Still waiting on a final electrical inspection.
The whole installation including gen set was half a day.
