NOTE
Percentage Fixed-Value Limitation (Open Loop)
The SmartLogger provides simplified active power percentage configuration as well as power
control automation, that is, to automatically adjust the active power derating percentage in
different periods of a day.

When setting this function, ensure that the user-defined DI port is not occupied. Otherwise,
the setting will fail.
When setting this function, ensure that the SmartLogger is correctly connected to a ripple
control receiver. (In Germany and some other European areas, a Ripple Control Receiver
is used to convert a power grid scheduling signal to a dry contact signal, in which a dry
contact is needed.)
DI parameters include DI1,
DI2, DI3, DI4, and
Percentage(%).

Description
Set this parameter to DI active scheduling.
 Sixteen levels are supported for the active power derating
percentage.
"√" indicates a low level. When the four DI ports of the

SmartLogger are connected, the ports are low-level ports.
When not connected, the ports are high-level ports.
 The percentage levels of DI1–DI4 should differ from each
other. Otherwise, an abnormal command will be
generated.

If the actual input DI signal is inconsistent with that
configured on the WebUI, the SmartLogger controls the
solar inverter to work at full load and the Abnormal Active
Schedule alarm is raised.
Description
Set this parameter to Percentage fixed-value limitation
(open loop) to control the maximum output power of the
solar inverter by time segment.
If the solar inverter needs to run with specified maximum
power in certain periods of a day, add setting records based
on site requirements.
When multiple time points are set, the solar inverter will run
with the maximum power specified for the time point that is
earlier than and the closest to the current system time. For
example, if you add 00:00:00 and 12:00:00 on the WebUI and
the current system current is 14:30:00, the solar inverter will
run with the maximum power specified for 12:00:00.
