Suggestions
1. Check whether the
grid connection
voltage exceeds the
upper threshold. If yes,
contact the local
power operator.
2. If you have confirmed
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.
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
affects the energy
yield of the PV plant,
contact the local
power operator.
