5.2.2 Device Detail
Click the corresponding device to query the device data, or select the device to export the device data.
5.3 Sits Setting
“Site setting” is equipped with three modules, which are “export limit control”, “power control” and “meter
reversion”. The “export limit control” and the “power control” are mutually exclusive so that only one can be enabled.
5.3.1 Export Limit Control
The purpose of the “export limit control” is to limit the power supplied to the grid. The inverter generates electricity
to the grid when the power source is positive, and takes electricity away from the grid when the power source is
negative. For example: The exported power is set to 0kW, the power generated by inverter is 5kW, the power load
consumed is 4kW, the inverter generates 1kW(5kW-4kW = 1kW), then DataHub will limit the power generated by
inverter to 4kW.
The control methods are divided into “average phase control” and “minimum phase control”. If the “export power”
were limited to 0kW, there will be no influence on a single-phase inverter, the inverter will not supply power to the
grid. As for a three-phase inverter, the “average phase control” is to average the power of the three phases generated
by the inverter. For example: the three-phase loads are 3kW, 4kW and 5kW respectively, a total of 12kW. Under the
“average phase control”, the power generated by the three-phase inverter is 4kW, 4kW, and 4kW respectively, a total
of 12kW, as well.
Under the “minimum phase control”, the power generated by the three-phase inverter is 3kW, which is the minimum
power of the three-phase loads.
*Note: Before using the “export limit control” function, make sure that a meter has been added to the DataHub. The
output of device will be abnormal when connecting to three phase three wire under “minimum phase control” mode.

5.3.2 Power Control
Power control includes “ripple control” and “DRM control” disable.
The “ripple control” is to control the active power and reactive power of the inverter according to the high or low
input of the DI port. There are a total of 16 situations for users to set the active and reactive power according to each
situation.
DRED control is applied to set the active power according to high or low input of the A1, D1, D2, D3 and D4 of DI
ports.
Mode Operate Explanation Note
DRM0 Close S9,S0 Inverter shutdown
DRM1 Close S9,S1,
disconnect S0
Close S1，charging power is 0% When two or more DRM
modes work at the same
time, take the optimal result
that can satisfy both of them.
DRM5
Close S9,S5
Inverter does not output active power
DRM6 Close S9,S6
The active power output by the inverter does
not exceed 50% of the rated power
DRM7 Close S9,S7
The active power output by the inverter does
not exceed 75% of the rated power
DRM8 Close S9,S8

5.6.2 Time Setting

DataHub 1000 User Manual
16
The time setting is to set the DataHub system time，including “time synchronization”, ”SolaXCloud synchronization”
and “other server synchronization”.
“Time synchronization”: The system corrects the time automatically.
“SolaXCloud synchronization”: The platform of SolaX sends a synchronization command to change the time of
system.
“Other server synchronization”: The IEC104 server sends a synchronization command to change the time of system.
5.6.3 Serial Port Settings
Serial port settings is to set the baud rate of the four serial ports of DataHub, the default value of the baud rate is
19200. The user can change the baud rate under the serial port according to the model.
*Note: The baud rate of the model under the serial port is consistent, and it is consistent with the serial port baud
rate set by datahub. The default value of the stop bit is 1.
5.6.4 Other Setting
The “platform setting” is the setting to upload the data to the platform, the data is sent to SolaXCloud by default, and
the other is sent to the IEC104 server.
The “database storage setting” is a path for inverters to store data. There are two storage paths including the “default”
and the “SD card”. The “default” is to store data on the Datahub.
Electricity price setting: Calculate the income through the electricity price and display it in the overview interface.
“CO₂ savings factor”: Calculate the amount of CO₂ through the coefficient and display it in the overview interface.
*Note
：
It is recommended to use a TF card with a capacity of 16G;
If the database storage path is a TF card, the TF card cannot be pulled out when the system is running. If you want
to pull out the TF card, you need to change the storage path to the default, and then pull out the TF card. (It is
recommended to unplug after power off)
