5.2.1 Add Device
The devices supported by DataHub are as follows: Inverters, Electricity Meters, and Environmental Monitors.
Select the device type under the serial port, set the starting address and the number of devices under the serial port,
and save these settings.
*Note: Please refer to Appendix 1 to check whether the baud rate of the model is 19200 or not. If the baud rate is not
19200, please refer to 5.6.3 Serial port setting for more details of setting baud rate.

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 “Other
Setting”. The “Export Limit Control” and the “PowerControl” are mutuallyexclusive so that onlyone can be enabled.

DataHub 1000 User Manual
13
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.
Before using the “Export Limit Control” function, make sure that two meters have been connected to the DataHub.
The purpose of two meters is to control speed and stability. Please refer to the schematic diagram for the specific wi
ring mode (as shown below).
The control mode includes “Total” and “Per Phase”.
“Total”: The Site Limit is the total export power (the combined production mimus the combined consumption) on all
the phases combined. Reverse current on one phase will count as negative power and can compensate for another
phase.
“Per Phase”: For three phase inverter connections, the inverter sets the limit on each phase to 1/3 of the total site
limit. Use this mode if there is a limit on each individual phase.
*Note:
1.The output of device will be abnormal when connecting to three phase three wire under “Per Phase” mode. If tw
ometers cannot be installed or other circumstances arise, please contact our presale service, we will provide you w
ith suitable installation suggestion according to specific local conditions.
2.For “Export Limit Control” function, please ensure that the meter is correctly connected to Datahub.
3.The equipment output may be abnormal if “Per Phase” is used for three-phase and three-wire connection.
4.Inverter shutdown after DataHub communication loss: After communication loss, the inverter will shut down in
10s (triggered once a Datahub communication succeed).
Inverter startup after Datahub communication connection: After communication connected, the inverter will start up
(triggered when all Datahub communication completed).

DataHub 1000 User Manual
14
Please refer to 5.4.3 “Parameter Setting” to enable Datahub communication loss shutdown and Datahub
communication connection startup. The corresponding Modbus addresses are respectively: 6152 and 6153; Set value:
“0”: Disable, “1”: Enable.
Datahub communication refers to: i) The communication between Datahub and inverters; ii) The communication
between Datahub and meters.
“Feed-in Buffer” is divided into 4 gears: “Disable”, “Low”, “Mid”, “High”.
The representative threshold values for each gear are respectively: 1%, 2.5%, 4.5% and 6.5%.
The definition of those threshold values is:
1. Except for “Disable”, when the load in other 3 gears is stable, taking power from the grid [the total power of
grid-connected inverter * threshold value] is preferred; In the “Disable” gear, when the load is stable, the output
power of grid-connected inverter ranges from [taking 1% of power] to [selling 1% of power]. [Selling 0% of
power] cannot be guaranteed, but less power will be taken from the grid.
2. When the load fluctuates within the range of [the total power of grid-connected inverter * threshold value], the
power of grid-connected inverter will not drop to 0 directly; Otherwise, the power of grid-connected inverter will
drop to 0 immediately and then the power will increase slowly.

5.3.2 Power Control
Power control includes “Ripple Control Receiver” and “DRED Control” disable.
The “Ripple Control Receiver” is to control the input active power and reactive power, output active power and
reactive power of the inverter and inverter off according to the high or low input of the DI port.
The green one indicates the high input of power; the white one indicates the low input of power. 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 A0, A1, D1, D2 and D3 of DI
ports.

Meter Reversion: When the current direction of the user's meter is reversed, there is no need to rewire, just turn on
the enable switch and submit this setting.
Main Breaker Limit: Valid only when the EV charger is available. By controlling the charging power of EV
charger, limit the current taken from the grid no more than the set value.
Maximum Unbalance Power: Valid only when the EV charger is available. By controlling the charging power of
EV charger, limit the power differences between each phase no more than the set value.
Plc enabled: Used with plc box of our company. If the plc box is used, turn on the “enable” switch and submit; If
the plc box is not used, Datahub will not found equipment even the “Enable” switch is turned on.
