Best of 2 options?

Thanks for comments on previous posts.

Fife, Scotland.
2350kwh usage pa.
Don’t have EV but do plan on it.

Both at £11,400

Option 1. Local installer

14 longi panels
Ecoflow 6kw inverter
10kwh Ecoflow battery. (2x5)
Bird protection
Installation + scaffold

Option 2. National installer + exclusive tariff.
14 longi panels
Sunsynk 7kwh inverter
10kwh sunsynk battery (2x5)
Ohm EV Charger
Bird protection
Installation + scaffold.

I don’t know enough to know how these batteries will affect the system or how easy to use they will be and how that should shape my decision.

Any advice or experience appreciated.
