What happens in ESS mode when grid voltage drops?

HI

A quick question on ESS fuctionality.

I understand that in case of grid-failure an ESS system will automatically switch to inverter + battery mode.

However, what happens if the voltage of the grid simply drops to 150V for say 30 seconds, for example?? ... and then returns

Hi Lazza, the default or set Grid settings in the inverter would apply

the default disconect settings are 180v so if you dropped to 150 the inverter would disconect and then reconect when the volatge increased to 187

the Low discount and the reconect voltages can be adjusted using VE Config.


the same happens on a high voltage as well


This is described in the Grid Section of the VEConfigure manual.
