Do I need a bigger inverter?

Redlander

I'm intending to get solar panels in the near future. An installer has proposed:
8 panels totalling 4.08 kWp
DC-coupled battery 10.36 kWh
Inverter 3.68 kW

Eventually our house will have:
Air source heat pump 5 kW
Electric oven
Induction hob
(No intention of getting an EV)

Clearly the inverter is adequate for the solar panels, but I'm hoping to use the battery for various flexible Octopus tariffs, so I'm thinking that the inverter will restrict the ability of the battery to discharge.

So should I upgrade the inverter to, say 5 kW? (I'm aware of the more stringent DNO approval conditions)
