Add option to override cloud property for detection of single or three phase inverters

[Gentleman1983]

We got the information, that currently solis cloud transfers wrong data through on the acOutputType property. This property is meant to be 0 for single phase inverters and something else for 3 phase inverters. Currently some users of single phase inverters have the issue that they receive value 1 for their inverters.

We should add an override to give a quick option to handle this issue on solis cloud until solis have fixed their cloud api data.
