8.11 The slew rate of the threshold values , either increase or decrease, are equal or
less than 0.05Hz/s for AC grid frequency and equal or less than 1V/s for AC grid
voltage starting from the maximum (or minimum) threshold value. During the
auto-test, the threshold value changes linearly and the measured values of the grid
will be displayed on the PC screen in real time. The threshold will move from the
maximum (or minimum) threshold value toward the measured value of the AC grid.
While the two value matching occurs, the PV grid-connected inverter will disconnect
the AC grid through the AC relays.
8.12 The matched value between the threshold and the AC grid and the software trip
time between the matching is recognized and the AC relays is open will be displayed
on the PC screen. The status of the each auto-test, Pass or Fail, will also be displayed
on the PC screen as well. The following will be shown on the PC screen if selecting
the MaxV mode.
