ECS battery warranty policy for germany
Hello, I have a question about the ECS2900 battery warranty policy.
Does anyone know why Germany have a different warranty policy?

Source: https://www.fox-ess.com/download/

ECS2900 battery warranty policy:
Energy throughput for Germany 8.35MWh versus for European Union 12.15MWh.

BATTERY WARRANTY (EU)
ECS2900 (10 years) 2.88kWh 12.15MWh

ECS BATTERY WARRANTY (DE)
ECS2900 (10 years) 2.88kWh 8.35MWh

Hope you can help
Kind regards
Thomas

Re: ECS battery warranty policy for germany
I know they enhanced the warranty last year by increasing it, is it possible the German warranty terms doc just hasn't been updated yet?

It might be worth dropping the german support team an email and asking, if you can update this thread for other users once you hear back.
