Domestic PV solar inverter noise

[VK3LU]

Thanks Steve, Peter and Damien.
The system I am looking at does not use micro inverters. The next size up uses power optimisers on each panel which bypass the panel if it is shaded, thereby effectively removing a series resistor. The optimisers are controlled by the inverter.
The inverter in the system I prefer is made by ABB a european manufacturer of long standing so that should be in my favour. The other inverters in their range are Chinese.
 It will be interesting!
