10.14.5 Overload Protection
When the PV array output power exceeds the MV Station permissible maximum input power,
MV Station will limit the power yield at maximum AC power point. If the temperature
exceeds the permissible value, MV Station will automatically stop operating unless the
condition resumes normal.
10.14.6 Ground Protection
The grounding cables are equipped with the leakage current sensor. When the leakage
current is detected to exceed the setting value, system will send instruction to stop the
module and display the fault type on the LCD screen.
10.14.7 Module Over-temperature Protection
IGBT modules inside the MV Station uses thermal sensor with high-precision to monitor the
real-time module temperature. Once the module temperature is detected to be high, DSP
will send direction to stop the MV Station or derate the output.
10.14.8 Internal Over-temperature Protection
The MV Station is equipped with high-precision thermal sensor to monitor the internal
temperature of the MV Station. Once the over-temperature is detected, the DSP will send an
instruction to stop the MV Station and keep safe operation.
