user’s manual inverter SE2.8i - SE3.8i - SE4i - SE5i
a. Maximum AC voltage threshold
b. Minimum AC voltage threshold
c. Maximum AC frequency threshold
d. Minimum AC frequency threshold
The standard threshold values and the trip time related to the specified sub test will be displayed on the PC screen before the Auto Test.
a. Maximum AC voltage threshold: 262 V ; < 0.1 s
b. Minimum AC voltage threshold: 188 V ; < 0.2 s
c. Maximum AC frequency threshold: 50.3 Hz ; < 0.06 s
d. Minimum AC frequency threshold: 49.7 Hz ; < 0.06 s
The slew rate of the threshold values, either increase or decrease, are < 0.05 Hz/s for frequency and < 1 V/s for voltage starting from the
maximum (or minimum) threshold value. During the Auto Test the threshold value changes linearly and the measured values of the AC grid
will be displayed on the PC screen.
The threshold will move from the maximum (or minimum) threshold value toward the measured value of the AC grid. While this match occurs
the inverter will disconnect the AC line and recognize if it disconnects.
