When a grid tied inverter (from a solar fed battery) is connected to the mains, it senses the mains voltage and disconnects if the mains voltage goes above 250VAC in UK (above 240VAC in Europe). However, the disconnection is not instantaneous, there is a slight delay. Therefore, it goes without saying that if multiple grid tied inverters are connected to the mains, then if the loads on the mains suddenly reduce, then the mains voltage will obviously shoot up significantly….voltages above 300VAC would surely not be unrealistic. A grid tied inverter cannot predict the future. Surely you agree?
