7.8.8 Custom Device, IEC103 Device, or IEC104 Device

Custom Device: The SmartLogger can connect to the third-party devices supporting the
Modbus-RTU protocol, such as the box-type transformer and environmental monitoring
instrument (EMI). Since the protocol information points vary depending on vendors, you need
to obtain a protocol information file in .cfg format from Huawei and import the file into the
SmartLogger for successfully connecting to a third-party device.
IEC103 Device: The SmartLogger can connect to the third-party devices supporting IEC103,
such as the relay protection or monitoring device like the box-type transformer. Since the
protocol information points vary depending on vendors, you need to obtain a protocol
information file in .cfg format from Huawei and import the file into the SmartLogger for
successfully connecting to a third-party device.
IEC104 Device: The SmartLogger can connect to the third-party devices supporting IEC104,
such as the relay protection or monitoring device like the box-type transformer. Since the
protocol information points vary depending on vendors, you need to obtain a protocol
information file in .cfg format from Huawei and import the file into the SmartLogger for
successfully connecting to a third-party device.

Description
The value ranges from 0–500 V, and the default
value is 50 V.
 If PV module compensation voltage direction
is set to PV– positive offset, the value indicates
the positive voltage between PV- and ground,
and the compensation range is 0–500 V.
 If PV module compensation voltage direction
is set to PV+ negative offset, the value indicates
the negative voltage between PV+ and ground,
and the compensation range is –500 V to 0 V.
NOTE
 If Compensation offset voltage is set to 500 V, the
PID module provides the maximum output to enhance
the voltage compensation effect. The output voltage
amplitude of the PID module is automatically capped
to ensure the safety of a PV power plant. The output
voltage amplitude is also related to the maximum
system DC-to-ground withstand voltage and maximum
output voltage.
 After this parameter is set and the PID module works
properly, use a multimeter that is set to the DC position
to measure the voltage between the PV input terminal
of the SUN2000 and ground. (For PV– positive offset,
check whether the voltage between PV– and ground is
greater than or equal to 0 V. For PV+ negative offset,
check whether the voltage between PV+ and ground is
equal to or less than 0 V.)
You can select Clear Data to clear active alarms
and historical alarms for the PID module.
