Having signed up to Axle (grid events only) I set the max discharge to 5kW but have never seen more than 4.6kW being sent to the grid during an event - and typically it is less....today for example my battery was at 70% and the house load was minimal at 600W, my inverter can supply 7kW and yet the export rate was only 4.62kWh
Battery export etc is set to maximum, my G99 agreement is for 5kW ..... the inverter max export is actually set to 18kW but with only 6kW of PV it wil;l obviously never get there
Have I missed somethimg

The max discharge is the maximum output power the inverter will run at, so any house load (and losses) have to be covered first and the remainder will be sent to the grid.

Your maximum output ‘may’ also be limited by your batteries as the BMS controls output current depending on both soc and temperature. On higher voltage batteries such as the EP12 these effects are less obvious (and limiting) unless it is very cold.

Battery temps shouldn't be an issue today, likewise as mentioned the house load was minimal so I would have expected the export to have been higher
