I have a Quattro 10K and it doesn't have an internal anti islanding device and therefore I'm not allowed to have it grid tied in South Africa, unless I install an external anti islanding device.
My question is, if I need anti islanding when I configure the grid in VE Configure to "None"
I want to run a virtual switch and NOT the ESS, specifically to avoid the anti islanding device. In this case the safety for not feeding back to the grid is done by what is called an internal "AC input relay" or "Back feed relay" in the Multi, but I'm not sure about the Quattro and I'm particularly not sure if you also need the external anti islanding device
I run 99.9% of the time off grid, but want the grid available should the battery charge drop too much. This can be done by Virtual switch "Ignore AC" function until battery is too low, then it will use some grid power
I think it must use Loss of mains detection (LOM) and the internal relay, as apposed to external safety device
