Notes:
- RTE: The value is for 1 cycle per day at 25°C ambient temperature and 97% DOD, at the end of the first year.
- MV side system efficiency: This value is the efficiency of the discharged power/charged power measured on the MV side after the system has completed a full discharge at an ambient temperature of 25°C.
