Communication and Monitoring

10.1 RS485
This series of inverters provide two RS485 ports. You can monitor one or more
inverters via RS485. The other RS485 port is used to connect a smart meter (stand-
alone anti-backflow function).
10.2 USB-A
USB-A port is mainly used to connect monitoring module or firmware update：
We can connect the external optional monitoring modules,such as Shine WIFI-X,
Shine Shine 4G-X, Shine LAN-X, etc. to the USB interface for monitoring.
Steps for installing the monitoring module: Make sure △ is on the front side, then insert
the datalogger and tighten the screws.

Maintenance and Cleaning

11.1 Checking Heat Dissipation
If the inverter regularly reduces its output power due to high temperature, please
improve the heat dissipation condition. Maybe you need to clean the heat sink.
11.2 Cleaning the Inverter
If the inverter is dirty, turn-off the AC breaker and DC switch ,waiting the inverter shut
down ,then clean the enclosure lid, the display, and the LEDs using only a wet cloth.
Do not use any cleaning agents (e.g. solvents or abrasives).
11.3 Checking the DC Disconnect
Check for externally visible damage and discoloration of the DC Disconnect and the
cables at regular intervals.If there is any visible damage to the DC Disconnect, or
visible discoloration or damage to the cables, contact the installer.
Ø
Once a year, turn the rotary switch of the DC Disconnect from the On position to
the Off position 5 times in succession. This cleans the contacts of the rotary
switch and prolongs the electrical endurance of the DC Disconnect.
