7 Debugging
7.1 Debug Inverter
1>Close the DC switch on the inverter. As long as the input DC voltage is greater than
250V, the inverter display will display the following message: If there is no mains
connection error, the inverter LED will turn red. If other information is displayed,
please refer to Chapter 9. If the debugging process encounters an unsolvable
problem, please contact customer service and perform the next step.
2>Close the circuit breaker or switch between the inverter and the grid. The inverter
starts the self-test countdown. After the self-test is normal, it will be connected to the
grid.
3>In normal operation, the leaves of the inverter indication window will turn green.
4>Complete debugging.
After the inverter is turned on normally, the inverter communication address can be set
through RS485, USB to WIFI module or server webpage. When the inverter is connected
by RS485 and multi-machine parallel communication, the inverter should be set to
different communication address; when the single machine communicates, the factory
default communication address can be used directly. Note: The inverter communication
address can be set from 1 to 254.
7.1.1 Set the PV inverter Communication Address
7.1.1.1 ShineBus Sets the Communication Address
The communication address of the inverter can be modified by the PC software ShineBus,
which is performed by a professional.
7.1.1.2 Mobile APP Set Communication Address
Refer to Section 8.2 Local Data Monitoring, download the mobile app and log in to the
monitoring interface to modify the communication address. This operation is performed
by a professional.
1>Select "Parameter Settings".
2>Enter the control password. (First time you need to set the control password, click
"Reset Password", jump to the page, enter the OSS account and password, the
distributor and installer can apply for the OSS account to Growatt, click "Login", set
Control password, the relevant settings can be used after the setting is successful.)
3>Select the setting item "Communication Address".
4>Click "Read" in the upper right corner to get the original communication address of
the machine.
5>Set the inverter communication address.
6>Read the inverter communication address and confirm that the setting is successful.
If the inverter is stored over one month, its default time and date may
looks wrong, the time and date should be reset before connection to the
grid.
7.1.1.3 Server WEB Page Set Communication Address
Refer to Section 8.1.2 to log in to the server. After obtaining the inverter data through
the collector, modify the device communication address. This operation is performed by a
professional.
1>Click "Settings" in "device list" to enter the advanced settings page;
2>Read the "30" register to get the current device address, the password is max + today
date (such as August 7th: max20190807);
3>When setting a new communication address, write the value of the "30" register as
the address to be set (1~254), and then click "Save";
4>After setting the communication address, you can read the value of the "30" register
to confirm whether the setting is successful.
