EPS cycling when EV on charge

Newbie here.

We have a newly installed plant with the EPS and battery storage. All works fine with Octopus Agile and a self-use mode.

Yesterday, while the EV was charging and the battery was also force-charging, we had a power outage. The EPS did its job and supported the home until the EV charger came back online and tripped the system. The EV charger stopped, and the EPS and battery powered the home until the EV charger started........repeat

Are there any particular settings that could stop this occuring? Obviously, it is not possible to predict a power cut when planning to charge the EV. The charger is a Pod-Point connected unit, and the EV load is 7kW.

What inverter and batteries do you have ?, suppling 7kW plus any house load is a significant load.

Most systems with EV’s are wired so that the EV is upstream of the inverter so that it doesn’t flatten your home battery.
