Parameter Description
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
(kW)
- Species the maximum active power
transmitted from the grid-tied point
to the power grid.
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.
Communication
disconnection
fail-safe
● Disable
● Enable
In the inverter anti-backfeeding
scenario, if this parameter is set to
Enable, the inverter will derate
according to the active power
derating percentage when the
communication between the inverter
and the Dongle is disconnected for a
period longer than Communication
disconnection detection time.
Communication
disconnection
detection time
- Species the time for determining
the communication disconnection
between the solar inverter and the
Dongle.
