Probably refers to island mode capability. The inverters can generate their own set point voltage, rather than relying on a voltage from the grid and responding to its inputs. One of the main downsides of renewables is that they are inverter driven and the output is always chasing and lagging behind its input, whereas a spinning turbine just keeps spinning via inertia, in spite of load fluctuations.
This has other advantages with possible reactive power compensation and load diversion on distribution and transmission networks, if fully implemented.
In this case, I wouldn’t be surprised if they have island mode capability because of unreliability from the grid.






Bangin. Just what I needed tonight, thanks.
