current and reverse current. The direct current (DC) circuit breaker or fuse
between each solar generator and inverter shall be provided based on solar
inverter input ratings.
Select DC cables based on the above inverter back-feed current and Isc PV
rating and Vmax ratings.
If the AC cable you choose is 16mm or larger,you need to break
the connection bewteen the two rubber rings which make up
the rubber insert as below.
NOTE!
Communication interface
This product has a series communication interfaces: such as RS485/RS232,
Dry contact .Operating information like output voltage, current, frequency,
fault information, etc., can be delivered to PC or other monitoring equipment
via these interfaces.
RS232 communication
RS 232 is one standard communication interface.It transmits the data between
PC and one single ZDNY inverter.Thus this method is generally used for software
updating and serviceman’s testing.There are two Rs232 connectors on the
inverter.The left one is used for updating the main DSP and subsidiary DSP.The
denition is as below.

3. Update the software on the computer.
4. After the update is nished,disconnect the Rs232 line,and install the
communication lid.
RS 485 communication
RS 485 is generally for multi inverters’ communication.Up to 32 inverters could
communicate at the same time,but wire length should be ≤1200m.System
monitor Sunny Logger should be congured to realize one PC communicates
with multi inverters at the same time.Through PC Sunny Logger could get real
time PV plants popertaing data.RS 485 connection use the RJ45 connector,RJ
45 PIN denition is as below.
●Connection Step:
1:Separate the RS 485 sealing connector.
