Major Cause ID = 1
The SUN2000 detects that
the phase voltage exceeds
the transient AC
overvoltage protection
threshold.
1. If the voltage at the grid
connection point is too high,
contact the local power
operator.
2. If you have conrmed that
the voltage at the grid
connection point exceeds the
upper threshold and obtained
consent from the local power
operator, modify the
overvoltage protection
thresholds.
3. Check whether the peak grid
voltage exceeds the upper
threshold.
2077 O-grid
output
overload
Major Cause ID = 1/2
The output is overloaded
or short-circuited.
1. Check whether the device
output is short-circuited.
2. Check whether the device
load conguration exceeds
the rated value.
