Automatic Add:

1. This function allows adding new devices without setting the inverter modbus address manually.

2. Select the device quantity and click “Add device automatically”.

3. The DataHub will distribute Modbus addresses to devices automatically and add them.

Notes:

Please refer to Appendix 1 in the PDF to check the baud rate of your model. If it is not 19200, you must adjust it in the “Serial port setting” section.

When connecting to X3-MIC-G2, ensure the meter is disabled.

The “Automatically add device” function is currently only applicable to X3-FTH and X3-MGA-G2, supporting a maximum of five devices per RS485 string. If the searched number is incorrect, click the button again.

Check the power intake and consumption on the meter in the “Overview” interface.

The purpose of “Export Limit Control” is to limit the power supplied to the grid. Before using this function, ensure that two meters are connected to the DataHub for control speed and stability.

Control Modes:

Total: The Site Limit is the total export power across all phases combined. Reverse current on one phase can compensate for another.

Per Phase: For three-phase inverter connections, the limit is set on each phase to 1/3 of the total site limit. Use this mode if there is a limit on each individual phase.

Notes:

Ensure the meter is correctly connected to the DataHub.

Output may be abnormal if “Per Phase” is used for three-phase, three-wire connections.

After a communication loss with the DataHub, the inverter will shut down in 10s. It will start up again once communication is restored.

To enable this feature, you may need to adjust Modbus addresses 6152 and 6153 in the “Parameter Setting” section.

“Feed-in Buffer” has 4 gears: “Disable”, “Low”, “Mid”, and “High”, with representative threshold values of 1%, 2.5%, 4.5%, and 6.5% respectively.

1. Except for “Disable”, when the load is stable, taking power from the grid [total power of grid-connected inverter * threshold value] is preferred. In the “Disable” gear, the output power ranges from [taking 1% of power] to [selling 1% of power].

2. When the load fluctuates within the range of [total power of grid-connected inverter * threshold value], the power of the grid-connected inverter will not drop to 0 directly. Otherwise, it will drop to 0 immediately and then increase slowly.

Power control includes “Ripple Control Receiver” and “DRED Control”.

Ripple Control Receiver: This controls the input/output active and reactive power of the inverter based on the high or low input of the DI port. There are 16 situations for users to set active and reactive power according to each combination of DI port states.

DRED Control: This sets the active power according to the high or low input of the A0, A1, D1, D2, and D3 ports. Different DRM modes correspond to specific actions:

Note: When two or more DRM modes work simultaneously, the optimal result that satisfies both is taken.

This function controls the inverter SVG switch and sets it to the corresponding mode in the setting period. You can enable or disable the switch, set an enable time window, and configure the Reactive Power Control mode and PF Value (0.80-1.00).

Note: This function is exclusive to X3-FORTH and X3-MEGA.

Priority setting of EV charger: Up to 2 EV chargers can be set as VIP. The available power is given priority to fully charging the VIP EV charger, and the remaining power is allocated to other EV chargers.

Charging station without electricity meter: Users set the rated power of the station according to the number of connected EV chargers, ensuring all can charge at the minimum charging power.

Main breaker limit: This function adjusts EV charger power so that the current drawn for each phase is less than the set value. If the load is high, the EV charger will be turned off.

Maximum unbalance power: This function reduces the charging power of the EV charger on the phase with maximum power, ensuring the power difference between phases is smaller than the default value.

This setting is used to calculate the benefit, displayed on the Overview interface as “Income&Saved”. It is divided into Basic Price and Additional Price.

Additional Price: Includes distribution fee, commission fee, and taxes.

Distribution Fee: Can be “Fixed” or “Unfixed”. Under “Unfixed”, you can set rules for “Week Distribution Fee” and “Holiday Distribution Fee” based on time and day.

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

Taxes: The ratio of total fees 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: The unit of electricity price set in the platform is MWH.

Parallel Point Meter: This function is for setting a parallel point meter. The grid-connected power of the homepage will use the value of this meter by default. For multiple-meter connections, manually select the “Parallel Point Meter SN”.

Meter Reversion: If a user’s meter is connected reversely, they don’t have to rewire. Simply turn on the “enable” switch for Meter Reversion and submit.

System On/Off: Turn on or off all devices connected to the DataHub.

Remote access settings: After being turned on, the device will be allowed to be visited remotely.

Inverter Active/Reactive Power Setting: Remotely set the active or reactive power of the inverter. The reactive power mode can be set to “OverExcited”, “UnderExcited”, “Fixed Reactive Power”, or “Disable”. Multiple selections are available.

Remote System Switch: Remotely switch inverters on or off. This can be operated in batches.

Parameter Setting: Professionals can read and write inverter parameters using “Modbus Opcode” options like “READ_HOLDING_REGISTERS” and “WRITE_SINGLE_REGISTER”. This can be operated in batches.

This function collects the PV power at different PV voltages for each PV string.
