Parameter Description
Active power
output limit for
fail-safe
- Species the derating value of the
inverter active power by percentage.
If the Dongle does not detect any
meter data or the communication
between the Dongle and the inverter
is disconnected, the Dongle delivers
the derating value of the inverter
active power by percentage.

Closed-loop
controller
● SDongle/
SmartLogger
● Inverter
● Set this parameter to SDongle/
SmartLogger when the
SmartLogger1000A is connected.
● If multiple inverters are cascaded,
set this parameter to SDongle/
SmartLogger.
● If there is only one inverter, set
this parameter to Inverter.
Limitation mode ● Total power
● Single-phase power
● If this parameter is set to Total
power, it indicates that no
backfeeding occurs for the three
phases.
● If this parameter is set to Single-
phase power, it indicates that no
backfeeding occurs for the phase
with the maximum power.
PV plant capacity - Species the total maximum active
power in the inverter cascading
scenario.
Maximum grid
feed-in power
(%)
- Species the percentage of the
maximum active power of the grid-
tied point to the PV plant capacity.
Power lowering
adjustment
period
- Species the shortest interval for a
single anti-backfeeding adjustment.
Maximum
protection time
- Species the time for detecting meter
data. If the Dongle does not detect
any meter data within the preset
time, the Dongle delivers the preset
value of the Active power output
limit for fail-safe to the inverter for
protection.
Power raising
threshold
- Species the threshold for raising the
inverter output power.
