Parameter
Description
Maximum grid feed-in
power
Indicates the maximum power that the device 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 device output
power.
Maximum protection
time
Specifies the maximum duration from the time when
the SmartLogger detects backflow to the time when
the device output power reaches 0.
Suggestion: Set this parameter based on the maximum
backflow duration allowed by the power grid
company.
Power raising
threshold
When the power supply from the grid reaches this
threshold, the devices 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.
Fail-safe power
threshold
Device 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.
Switch-off state
feedback port
Set this parameter to the DI port that reports the
switch-off status.
Switch-on state
feedback port
Set this parameter to the DI port that reports the
switch-on status.
Step 2 Verify that the SmartLogger can remotely turn on and off circuit breakers in
scenarios with circuit breakers.
●
Click Switch off and check that the circuit breaker is switched off properly.
●
Click Switch on and check that the circuit breaker is switched on properly.
