※ Test Conditions: Temperature 25°C/77°F, at the beginning of life.
※ Energy is measured under specic conditions from LG Energy Solution (0.3CCCV/0.3CC).
1) Value for battery pack only. Maximal usable energy at the AC output may vary by condition, such as
inverter efciency, conguration and temperature.
2) Peak current excludes repeated short duration (less than 10 sec. of current pattern).
2.1.3 Arc Flash Protection Calculations
In order to protect personnel from the possibility of getting injured by an
arc ash Hazard, Arc ash calculation of the battery system is estimated
with the Incident Energy calculations refer to Annex D of NFPA 70E.
