This section describes how to set export limitations on Smartlogger3000 using Fusion Solar App.
The Export Limitation feature is mainly used in the self-use scenario. The SmartLogger detects the active power of the grid-tied point electric meter, controls the active output of the inverter in a closed-loop manner, prevents the inverter output power from being transmitted to the power grid, and maximizes the inverter power generation for local load consumption.
Step 1. Access the Smartlogger using a mobile phone.
Step 2. Add Power Meter.
We suppose that we install Smart Power Sensor DTSU666-H as an example.
The communication address for Smart Power Sensor DTSU666-H is 11.
Step 3. Set the model of the power meter.
Step 4. Set export limitations.
|Electric meter power direction
|When the inverter has no output power, set this parameter to Positive if the active power reading of the power meter is positive. Otherwise, set this
parameter to Reverse.
Total power: controls the total power at the grid-tied point to limit the power fed to the power grid.
Single-phase power: controls the power of each phase at the grid-tied point to limit the power fed to the power grid.
|Maximum grid feed-in power
|Indicates the maximum power that the inverter can feed into the power grid.
Suggestion: Set this parameter based on the export limitation threshold allowed by the power grid company.
|Power lowering adjustment period
|Specifies the period for lowering the inverter output power.
|Maximum protection time
|Specifies the maximum duration from the time when the SmartLogger detects backflow to the time when the inverter output power reaches 0.
Suggestion: Set this parameter based on the maximum backflow duration allowed by the power grid
|Power raising threshold
|When the power supply from the grid reaches this threshold, the inverters start to raise their output power. The recommended value of this parameter is 1% to 2% of Pn, where Pn is the total rated output power of inverters and can be queried on the overview page of the SmartLogger.
