Fox ESS battery and evnex x22 - any issues

Hi hive mind

Im getting a FoxESS 48kw battery with 15kw 3 phase h3 smart inverter next week. Needless to say I expect to be charging the EVs from the battery a lot of the time and solar diversion maybe less if a thing for me than it has been. But if the battery is full, diversion will still be on the table. The company doing the install has installed evnex before, although not mine. Any thoughts or tips for me?
