* Max. operating DC voltage is 950V, max. withstanding DC voltage is 1000V
** Max apparent power from the grid means the maximum power imported from the utility grid used to satisfy the backup loads and charge the battery
*** The output power will exceed the rated value only when the power in the PV array is sufficient, and the duration of the overload is related to the overload power
