Device Detail

Click the corresponding device to query the device data, or select the device to export the device data.

Sits Setting

“Site Setting” is equipped with three modules, which are “Export Limit Control”, “Power Control”, “Electricity Price Setting”, “Meter Setting” and “Other Setting”. The “Export Limit Control” and the “Power Control” are mutually exclusive so that only one can be enabled.

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 tw0 meters cannot be installed or other circumstances arise, please contact our presale service, we will provide you with 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 connections.
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).

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.

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.

Electricity Price Setting

Electricity Price Setting: Set the electricity price to calculate the benefit, which is displayed on the Overview interface as “Income&Saved”.

Distribution Fee: Distribution Fee Refers to fees of the electric grid infrastructure, including “Fixed” and “Unfixed” ones. Under the “Unfixed” mode, users can choose “Week Distribution Fee” and “Holiday Distribution Fee” to set the calculating rules, with the Holiday calculating rules have higher superiority.

Commission Fee: Commission charge that the seller has to pay when selling electricity to the grid.

Taxes: The ratio of total fees that the buyer has to pay as taxes.

Equation:

The price of buying electricity = (electricity fees + distribution fees) * (1+taxes rate) The price of selling electricity = fees of selling electricity – commission fees

*Note: Distribution Fee, Commission Fee and Taxes are parameters used to set region electricity price in the Smart Scene.

Meter Setting
