Description
The frequency level of the grid is
lower than the lower limit
The amount of frequency change is
higher than the limit
The residual current is higher than the
limit
DC offset current is added to the grid Automatically restart after
There was a power failure
The average voltage of the grid for 10
minutes is higher than the limit
The voltage level of BAT A is higher
than the limit
than the lower limit
than the limit
The current level of BAT A suddenly
spikes above the limit
the lower limit
A State Error occurs in BAT A
BAT A power goes into power saving
mode
