Growatt Wifi Dongle

Common Problems (In Order of Occurrence):

1. Intermittent Connectivity:
   • Sometimes, the Shine-X Dongle may lose connection to the WiFi network, causing data gaps in monitoring.
2. Compatibility Issues:
   • Users with single-band 5GHz routers may face compatibility issues.
   • Solution: Use a compatible router or switch to a dual-band router.
3. Data Lag or Delay:
   • Occasionally, there might be a delay in data transmission from the inverter to the monitoring platform.
   • Solution: Verify that the Dongle is functioning properly and consider adjusting the data transfer interval.

The list above is from there own accounts of why the dongle is so bad, Here is what we found….
The connectivity issue is at both ends. The dongles wifi performance is poor the range of 50 meters line of sight is reduced to near zero if there is a wall.. a fake wall not a real one…
the other end of the problem is the servers, Growatt dongle data is sent to china where it is hosted on a website, with servers holding and processing all data from all its wifi connected owners world wide. it breaks down fairly often..

Data delay, lag and wrong data that is just made up..
Delays are usually due to two things, its broke, or there is a wifi connection issue. the update interval is 5 seconds. you can miss a cycle or five and if you reboot you can end up being locked out. you should NOT increase the time intervals any lower than 5 seconds.
The data is NOT local, so your data comes from china. but you have to send it there first. both transmissions take a little time or can fail, if it fails a few times they will just use fake data.

Surely not fake data? if you do have one, plug it in in the morning, remove it around 11 -13:00 and plug it back in. wait an hour or so and then look at the wonderful production numbers. it would not be so bad if they just had the same level across the time, but it can make up this idealized data set for you.

For the most part, this device came from frustration. data sometimes, but 5 seconds intervals if you were lucky is a joke, while for some managing a install and Tuning panels is impossible with the long delays and then hours of outages.

You are totally reliant on a internet connection and China to make this “app” work, and we had log in issues and again outages here too. after a few weeks it was time to end it.
