RS 485/NFI/DRM
RS 485 is one standard communication interface which can transmit the real
data from inverter to PC or other monitoring equipments.
a. RS 485
b. X1-NFI(optional)
X-NFI is integrated with meter, it can control the output and reduce the
power of inverter, to assure the redundant power will not feed into Grid,
X-NFI communication use terminal block on the communication board
in the inverter.
Please refer to the X-NFI user manual for details.
The PIN de nitions of RS 485/NFI interface are as below.

1. Prepare RJ45 connector and a communication cable.
2. Trip the insulation from the communication cable.
3. Let the communication cable pass though the waterproof connector with
RJ45, then insert it into the RJ45 connector following the PIN definition rule.
4. Crimp the RJ45 connector with the crimping plier.
5. Insert the cable into the RS 485/NFI port of the inverter, and tighten the
waterproof connector.
DRM is provided to support several demand response modes by giving
control signals as below.
