VI. Firmware update
There are 2 ways to update firmware for EV charger
1. Update by SD card
2. Update on parameter setting page
6.1 Update by SD card
1. Prepare a microSD card with capacity not greater than 4G. Format the SD card using
FAT32.
The firmware file must be named as “App.bin”.
2. In the root directory of the SD card, rename the firmware file as “App.bin”. And create a
txt file with name of “UploadConfig.txt”.
3. Open the txt file, write “state=1” in it and save the file.
4. Insert the SD card into the charger, turn off and back on the charger, the update will start
automatically. The indicator will first flash red and then flash green with a long beep as the
end of the update(sometimes the beep sound may not be clearly heard). After the update is
done, turn off the charger and remove the SD card.

5. Check the current FW version on LCD or the parameter setting page.
To check FW version on the paramete setting page
Connect the charger to computer via a network cable, the computer’s IP must be within the
192.168.1.x segment(x is any value between 1 and 255 except 5).Open the web browser,
type in the charger’s default IP of “http://192.168.1.5:8080” and click enter, then you can
check the firmware version on the appeared parameter setting page.

21 22
6.2 Update on parameter setting page
Using this method for update doesn’t require any specific name for the firmware file.
1. Connect the charger to a computer with IP address set as 192.168.1.x(x can be any value
between 1 and 255 except 5) via a network cable. Open web browser and type in the
charger’s default IP address–http://192.168.1.5:8080, click enter then you’ll get into the
parameter setting page.
2. Scroll down to the below field.
During the update, the LED indicator will behave as below,
First flash red and goes out with a short beep sound, during this period the firmware file is
transmitted to the charger’s flash memory from the computer;
Then flash red again for some seconds and quickly change to green light flashing. During this
period, the charger is updating the firmware to its micro controller.
When the greenlight goes out, there will be a long beep sound. That means the firmware is
successfully updated.
The beep sound may not be audible with the front cover fixed on the charger.
If the update doesn’t start after click “Upload”, Turn off and back on the charge to try again.
4. You might see below content. If the charger is already successfully reboot after the
firmware update, close the browser and open it again to check the current firmware version.
3. Click the “Browse” button and select the firmware file. Click “Upload”, then update will
start automatically.

VII. Troubleshooting
7.1 Troubleshoot by LED behavior or LCD display
If fault occurs, users can check the fault information on the LCD or by the number of blinks
of the LED indicator light. Each fault is indicated with a sequence of different numbers of
LCD blinking. A pause of 3 seconds between each sequence indicates the beginning or end
of a sequence. If multiple faults happen at the same time, each sequence of blinking shows
in chronological order at an interval of 3 seconds.

7.2 Firmware update fails
7.2.1 Firmware update failure with SD card:
a. Check if the capacity is over 4G bytes,please use a SD card of less than 4G to retry;
b. Check if the SD card is formatted with FAT32;
c. Check if the firmware file is renamed as App.bin;
d. Check if you have filled in “state=1” in the UploadConfig.txt file.
7.2.2 Firmware update failure with laptop:
Please try with IE browser. Or reboot the laptop to retry.
7.3 WiFi connection&APP issue
a. Check WiFi signal strength;
Signal strength on PC:
Signal strength on mobile:

25 26
b. Please check and input the correct WiFi SSID and password to retry;
If you check the WiFi setting on the APP, please
turn off and back on the charger and connect
your mobile to the WiFi emitted by the charger
for checking and setting.
c. Check if there is access control in the router, e.g. MAC filtering, port blocking, etc.
To verify this, you can use your mobile phone to create a hotspot and try to connect the
charger to this mobile hotspot. If charger can connect to the hotspot, but cannot connect to
the router, there must be access control in the router, please check with the site owner for
this.
Check if charger is connected on Device list of the hotspot setting page
d. Some routers have 2 WiFi, one is 2.4GHz, the other is 5GHz. Most homes just use the
5GHz WiFi as their default WiFi. But the charger can only connect to the 2.4GHz WiFi. So if
the charger can connect to your mobile phone hotspot, but cannot connect to the home
WiFi. Please check with the home owner or check on their router to see if you are using the
5GHz WiFi. Please do use the 2.4GHz WiFi for charger connection.

e. Check if the charger is still connected to the computer. Please unplug it from computer
otherwise the charger won’t connect to the back-office server.
f. Check if server address is correct in the“Server URL” field. The correct setting is :
ws://charge.growatt.com:80/ocpp/ws
7.4 Cannot accessparameter setting page
a. Check if you have connected the charger to your computer,
b. Check if you have change the computer’s IP to 192.168.1.x(x can be any value between 1
and 255 except 5).
To set a static IP on your Windows computer:
(1). Click Start Menu>Control Panel>Network and Sharing Center. (For Windows 8 and
higher, search for and open Control Panel and select Network and Internet).
(2). Click Change adapter settings.
27 28
(3). Right-click on Local Area Connection and click on Properties.
(4). Select Internet Protocol Version 4 (TCP/IPv4) and click on Properties.
(5). Select "Use the following IP address" and enter the IP address, Subnet Mask, Default
Gateway. Click OK and close the Local Area Connection properties window.

Reset button
c. Check what web browser is being used, it’s suggested to use Firefox or IE, Chrome cannot
be used to update firmware.
d. Check if you have input the complete content, which is http://192.168.1.5:8080, in the
address field, do not leave out the http:// or the“:8080”.
e. Sometimes you may need to restart the charger to access its parameter setting page.
f. If you have changed the charger’s IP to other value and cannot remember, you can restore
the charger to factory setting by long press the reset button. Then you can access it using
http://192.168.1.5:8080
Please note: After restoring the charger to factory setting, you’ll need to reset the charger ID
and server url, otherwise the charger won’t be connected to the back-office server.
29 30
c. Check if off-peak charging is set and if charger’s time is correct.
If off-peak charging is set, charge can only start within the charging allowed time period.
7.5 Charging issue
If charging cannot start after the car is plugged in,
APP/RFID: Charge can only be started/stopped by APP or RFID card, and the charger must be
connected to the back office server already;
RFID: Charge can only be started/stopped by RFID card;
Plug&Charge: Charge will start automatically when car is plugged in.
a. Check if the red emergency stop button is pressed.
.
