Growatt Wifi Module, Plugs directly into Inverter USB Port, view on your phone

Mobile Phone App : user manual can be downloaded here:


Web Interface: (Optional)



Note:  If after completing the registration process by following the manual, the LED flashes blue, but are unable to view any data, we need to make sure the Wifi Module is connecting to the USA Server. (Just been created recently)

NOTE #1 : a press of more than 6 seconds duration resets the Wifi Module. (Tiny hole, use a sharp pointed object)

NOTE #2 a press of less than 0.5 sec puts the Wifi Module into Access Point Mode (Thus transmits its Wifi SSID). (Tiny hole, use a sharp pointed object)

This is also an alternative registration method:

  1. Connect Wifi Module to USB Port on inverter
  2. Insert pin or another tiny sharp object into the tiny LED hole for 6 or more few seconds, until the Light is steady White(ish)
  3. Insert pin or another tiny sharp object into the tiny LED hole for less than 0.5 seconds, until the Light is steady /flashing White(ish)
  4. On your phone or PC connect to the Wifi Name that matches the serial number on the Wifi Module (Hint -also on the box)
  5. Sometimes your phone will ask if it is ok to connect to this network without internet access (affirm this and connect anyway)
  6. From your phone or PC browser, type in the “” IP address just as shown here, and go.
  7. log into the blue login screen “admin”  password “12345678” see example:
  8. Configure your Wifi credentials for this module to connect to your Wifi, (Please use simple Alpha Numeric SSIDs and Passwords – no special characters see example:


wifi Name SSID name example  “MyWifi-33” would not work,  because it has a “-”  in it must exclude non AlphaNumeric Characters “!@#$%^&*() – ” etc no spaces

Wifi Password MUST be longer than 10 chars  and MUST EXCLUDE and non AlphaNumeric Characters “!@#$%^&*() – ” etc no spaces


  1. /manuals/gw/WifiConfig-1.jpg
  2. Now the next important part, set the domain FROM TO see example:
  3. Click Apply, then click the button to restart and save changes. (Wifi Hotspot should vanish))
  4. If successful,  the LED should start flashing BLUE (it is communicating to the new server) – If Not, repeat procedure, unplug wifi module from USB Port, and start again from #1 above  (sometimes the inverter may need to be completely powered off – battery disconnected in order to restart the process )
  5. Now inside your APP (if you havent already done so),  go to your plant, add or browse dataloggers,  (Blue “+” sign in the top right corner……and add this one to your plant – in 5 mins or less you should start seeing some data.)


If after all of this, and the LED Will NOT Flash BLUE,  you may have a firewall problem on your home router, it may be blocking port 5279,  please go to and figure out how to open up this port on YOUR particular Internet Router.

  1. Hint,  dangerous…but cool.  you can change parameters on your Growatt Inverter remotely, if prompted for a password, its “growatt”  followed by today’s date e.g. 20201225  (changes every day)  example  Christmas day password would be “growatt20201225”, next day would be “growatt20201226” etc…
  2. Remember this can screw things up in a bad way if you are not careful


For use on the inverters in our store (remote monitoring)

    I recently ordered the WiFi module (on sale) and received it promptly. I have to say that I spent a couple of hours trying to get it registered and set up to my network, and was having no luck at all. A few days later I tried again using the ‘alternate registration method’, but this time I just brought the module into the house and plugged it into a 5V USB charger. With the device on my desk, it made it much easier to go through the setup steps on my phone. It took multiple attempts but I was finally able to get it to connect to my router. The server name was already correct. Also, because of the limitations on acceptable WiFi names and passwords, I created a guest login account on my router using the required parameters just for this device, which saved me having to do anything with my primary WiFi information (which would have been a deal killer given I have 80+ smart home devices). When I took the module out to the inverter and plugged it in, it connected and started flashing blue. I then downloaded and logged into the app. Since I had already registered the device serial # using a different phone, the app immediately saw it and started displaying data. Huzzah!

    So to summarize, do the initial setup using only a USB charger/supply away from the inverter, and use a guest network if available to save having to mess with existing WiFi connected devices.

    This item is useless as far as logging the metrics and trying to calculate remaining battery capacity. The problem is with the server. It should zero out the solar charge, discharge, load consumption metrics every night at at midnight, and then begin capturing another days worth of data. Sometimes it does and other times it doesn’t. Also, if you shut down the inverter, the Shine Wifi module has to be unplugged and plugged back in again to reconnect to your home Wifi, so don’t attach it to the USB port using the tiny screws provided. I wasted a hundred bucks on two of these and endured the exceedingly painful task of setting them up. Anybody who believes the Chinese are going to supplant the US as the dominant power in the world needs to buy this product and read the accompanying Chinglish manual. If they have to do anything more complicated than assembly manufacturing, they are still a third world economy.

      Yup, the growatt wifi, is a touchy subject, thats why we have the troubleshooting guide in the listing description, use Solar-Assistant, your data is not sent over to a server somewhere out there.
      Battery capacity is only really calculated if the batteries are communication to the growatt directly via BMS comms. use a smart shunt for any other non communication SOC

    I posted a negative review (08/10/2022) on this item detailing my dis-satisfaction with the makers inaccuracy due to amateurish coding and lack of accuracy of the data collected. Will not purchase another one of these items. I also will not shop Watts24/7 anymore unless this review is posted. If you can only post positive reviews on this site, then reviews are worthless and I will publicize Watts24/7 unwillingness to publish negative reviews.
