Double-click on "ISP TOOL V4.2.exe" to install the upgrade tool on your laptop and you should find this icon on your desktop. Make sure your inverter is working in battery-inverter mode without any load. Find the following USB cable from the packaging.
Connect your laptop to the Growatt inverter. Connect the USB port to your laptop. Connect the "square-ish looking" plug into the inverter (indicated USB).
Upgrade the inverter's firmware on your laptop. Double-click on the desktop icon to start the process.
Your process should be the following:
Step 1: Select the COM port, only one should be showing, select that one. (It could be COM 1, COM 2, Com 3...etc)
Step 2: Select the file F030_SK041.03_20210203_A.bin and click on OPEN
Step 3: Click on the FUNCTION button and change it from "Closed" to "Opened"
Step 4: Click on the FLASH button and the update process will start.
During the 7 to 8 minutes upgrade process, DO NOT touch the USB connections or the cable. Another reminder: make sure that the inverter is working in battery-inverter mode without any load.
Repeat Step 2 to Step 4 with the second file: "F2809_SK040.03_20210204_A.bin"
Again, run the file by clicking FLASH:
The firmware is updated, but make sure to reset the inverter.
