7.2.6 Setting grid model choice
This function is disabled when the inverter work in the normal state, you must turn off
the AC(disconnect) separate unit, and the inverter LCD will display an error 'NO AC
Connection' , LED turns red, then this model choice function is enable.
On the set situation page knock to 'Set Grid type' double knock to enter 'Grid Tx:
xxxV' knock to select the grid model. Need to wait for 10S until the LCD background
light gone out then the inverter will automatically restart. Turn on the AC(disconnect)
separate unit, inverter will operate normally.

7.3 Communications
7.3.1 RS485 communication(standard)
Users can connect to the computer through the RS485 port, then use the shinebus
software that communicates with inverter to analyze the inverter working state.It is
convenient for user to know the inverter's real-time working state and the history
working information.
7.3.2 WiFi/RF/GPRS Wireless communication(Optional)
WiFi/RF/GPRS communication modules (It is available from Growatt) can be used as
an optional monitoring device. They are wireless device used to monitor inverter. They
transmits the data collected from the inverter to the server. User could get access to
the inverter data by accessing the sever. More details can be found in the Wifi module
manual.
1. Connect the AC breaker of the inverter.
2.Turn on the dc switch, and the inverter will start automatically when the input voltage
is higher than 100 V.
8.1 Start-Up the inverter
8.2 Turn-off the Inverter
Turn-off the inverter step:
1.Disconect the line circuit breaker from single-phases grid and prevent it from being
reactivated.
2.Turn off the DC Switch.
3.Check the inverter operating status.
4.Waiting until LCD display go out, the inverter is shut dwon..
Do not disconnect the DC connectors under load.
DANGER
Start-up and shut down the inverter

Maintenance and Cleaning 9
9.1 Checking Heat Dissipation
9.2 Cleaning the Inverter
9.3 Checking the DC Disconnect
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.
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).
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.
