Major Cause ID = 1
The grid voltage exceeds the
upper threshold or the
overvoltage duration exceeds the
time that triggers high voltage
ride-through (HVRT).
1. Check whether the grid
connection voltage
exceeds the upper
threshold. If yes, contact
the local power operator.
2. If you have
conrmed that
the grid connection
voltage exceeds the upper
threshold and have
obtained the consent of
the local power operator,
modify the overvoltage
protection threshold.
3. Check whether the peak
grid voltage exceeds the
upper threshold.

e
Major Cause ID = 1
The dierence between grid
phase voltages exceeds the upper
threshold.
1. Check that the grid
voltage is within the
normal range.
2. Check that the AC output
power cable is correctly
connected. If the AC
output power cable is
correctly connected, yet
the alarm persists and
aects the energy yield of
the PV plant, contact the
local power operator.
