of point of common coupling (PCC) will be limited to the set Reflux
Power limitation.
Both the Hard Anti-Reflux Control and Anti-Reflux Control can be
used together. However, when the Hard Anti-Reflux control is
enabled, the Anti-Reflux power limitation cannot exceed the Reflux
power limitation. If the Reflux power exceeds the Reflux power
limitation, the overload protection will be triggered.
When the communication signal with the electricity meter is lost, the
output power of the inverter is limited to the set value of the soft
export limit and the fault protection will not be triggered. When the
Hard Anti-Reflux Control is enabled, loss of signal with the meter
triggers the inverter's fault protection.
The inverter output of HYD 5-20KTL-3PH series inverter has 4 sets of
relays, which are electrically connected to the output end R/S/T/N
respectively to ensure the continuity of the electrical connection of
load R/S/T/N when the inverter is switched off the grid.
NOTE
•
Anti-Reflux Function = Export Limit function
•
Reflux Power = Export Power
•
Hard Anti-Reflux control = Hard feed-in limitation control
•
Anti-Reflux Control = Soft feed-in limitation control

Obtaining grid information via System A
Connect the wires according to the wiring method as shown in System
A, enable the Anti-Reflux Power function and set the limitation
