Hi,
2 questions please
1/ If I have a Fox 10kw inverter and 2 x Fox 11kw batteries installed, what would the max charge/discharge rate of the batteries please?
2/ Can the batteries be stacked vertcally in line? i.e. one on the floor and fixed to the wall, and another in front of it on the floor?

1/ If I have a Fox 10kw inverter and 2 x Fox 11kw batteries installed, what would the max charge/discharge rate of the batteries please?
The EP11 battery is rated at nominal voltage 384V and a maximum continuous discharge current of 27A (at 25C) so each EP11 would be able to deliver 10.368kWh and as they are in parallel that would be a max discharge power of >20kWh (your inverter supports a max AC output of 10kW which would be the limiting factor).
In terms of charging the 'recommended' charge current to maintain maximum life is 13.5A (384V*13.5 = 5.184kW), so the 2 batteries would again be perfectly rated for your 10kW inverter. The EP11 battery can charge at a maximum of 27A continuously if needed but this may affect their lifetime if done regularly.
2/ Can the batteries be stacked vertcally in line? i.e. one on the floor and fixed to the wall, and another in front of it on the floor?
No they have to have a minimum of 300mm left around the battery pack for cooling and they need to be fixed to a wall (tipping risk from a 100kg pack), so the batteries would have to be mounted next to each other.
