You are advised to choose Settings > Grid connection with limited power and enable the
grid connection with limited power function.
To enable this function, you need to set power meter, inverter, and grid connection with
limited power parameters. This section describes how to set grid connection with limited
power parameters.
Before setting the parameters, ensure that a power meter has been connected to the
SmartLogger.
Step 1 Set export limitation parameters and click Submit.
Parameter
Description
Active power control
mode
Set this parameter to Grid connection with limited power
(kW).
Power meter
Set this parameter to Smart meter. Otherwise, the function
will not take effect.
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.
Limitation mode
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 company.
Power raising threshold
Specifies the threshold for raising the inverter output power.
Fail-safe power threshold
Inverter output power percentage is controlled by the
SmartLogger when communication between the SmartLogger
and the power meter is abnormal.
Switch-off with 0% power
limit
Specifies whether the DO port is allowed to control
switch-off.
Switch-off control port
Set this parameter to the DO port that controls switch-off.
Switch-on control port
Set this parameter to the DO port that controls switch-on.
