550 Installation and Connection Diagram
Step 1: Install the LCF Filter Used to Eliminate PLCC Communication Interference
(Skip When There is No Monitoring Device)
Select a suitable AC cable to connect the LCF to the power distribution box or AC outlet, pay
attention to the current carrying capacity of the AC cable, and must adapt to the total output
current of all microinverters connected to the filter. For example, when there are 2
microinverters, the cable carrying capacity must be greater than 5A, and when there are 8
microinverters, the cable carrying capacity must be greater than 20A. A 10AWG cable is
recommended.
Note
:
If
the
number
of
connected

you
need
to

Step 2: Install the Monitoring Device EMU (Skip If There is No Monitoring Device)
a. Connect L and N of EMU to LCF filter, and pay attention to the polarity of L and N.
NOTE: The connection must be on the side away from the distribution box or outlet.
b. Connect the network cable (RJ45 cable) of the EMU to the LAN port of the router that can
directly access the Internet.
