Hi
So my system specs would be 2*Pylon tech YS2000C 2.4KWh batterys , Sofar HYD4000inverter and 13*VertexS Trina Solar 380w panels

A 4kW inverter means it's a 4kW system, which is odd as the inverter itself can limit export to the 3.68kW minimum if no DNO permission is sought, so a 5kW version seems to be a much better idea.

You tend to find that inverters with overspecced panels do better in the winter months, so 5kw of panels through a 4kw inverter will probably do quite well, and likely better than a 5kw inverter in the poorer sun months.
My 6.6kw are doing far better through a single (dual mppt) 3.6kw inverter this year than the two (single mppt) 3.3kw inverters I had them running through last year, but I will need to move them off that 3.6kw before April when I'll be wanting as much of that 6.6kw as I can get.

Sofar inverters have a decent name, as do pylontech batteries, though I confess I don't know that model number, most folks use the 2000b or 2000plus batteries.
Edit I think that's a us2000c which is like the 2000b but with 95% discharge instead of 90%

I would say though that the lux hybrid inverter would probably give more flexibility and certainly more control through the app than the sofar though (I've had sofar and lux ac battery inverters) so may be worth asking if you could get a lux inverter instead??
