Solution
51
ConsistentFa
ult_DCI
The sample value of the
DCI between the master
DSP and the slave DSP is
not consistent
52
ConsistentFa
ult_GFCI
The sample value of the
GFCI between the master
DSP and the slave DSP is
not consistent
53
SpiCommLos
e
The SPI communication
between the master DSP
and the slave DSP is faulty
54
SciCommLos
e
The SCI communication
between the control board
and communications
board is faulty
55
RelayTestFail
Grid relay error
56
PvIsoFault
The insulation resistance
is too low
Check the insulation resistance
between the PV generator and
earth (ground), and rectify the error
in the event of short-circuiting.
57
OverTempFa
ult_Inv
The temperature of the
inverter is too high
Ensure that the mounting position
and method both comply with the
necessary requirements.
Check whether the ambient
temperature at the installation
location exceeds the upper limit
value. If so, improve the ventilation
in order to reduce the temperature.
58
OverTempFa
ult_Boost
The DC/DC booster
temperature is too high
59
OverTempFa
ult_Env
The ambient temperature
is too high
