Firstly,hello the Givenergy community.Im Pete a newbie so go easy on me if my terminology isn’t correct,I know what you I.T. guys are like!
I have an issue with my AC coupled Inverter not connecting to the battery,this has been confirmed by an installer who thought it might if been the battery that was the issue as it had run flat after being off all through winter due to other issues with the system.
Anyhow he charged the battery back up to full and tried with Givenergy to get me back up and running, to no avail.
He left and said there was a Comms issue with the inverter and said he couldn’t do anymore and I was to speak to them myself regards warranty (runs out next year)and getting a replacement…they literally went bust a week or two after this so I was left with a £380 bill for the installer and no better off.
My question is,can I check anything that might of been overlooked ie.on the portal?
Or is just a case of replacing the inverter and hoping it will connect to the battery?
Is there anyone at Givenergy I can still speak to regarding this issue?
Thanks,Pete
A lot of comms issues are due to incorrect installation. It is important that a “twisted pair” is used for each communication channel. Check with your installer (or better check yourself) that this is the case. Easily fixed if cores from different pairs have been used, or cores have been “doubled-up” (a common mistake).. Not so easy to fix if non twisted cable has been used, but it is important to do so.
Hi WillyReckitt,
Thanks for your re
ply and suggestion!
Finally got time to investigate 
Can you please confirm where these twisted pairs are located in the inverter?
Took cover off and nothing stands out,ribbon cable,mains cables to battery and 2 core cables .
Thanks,Pete
Similar issue here, mine was solved by re-introducing the GivEnergy equip. to my WiFi Network..
If your inverter or battery has gone offline (for example after changing your router, SSID, or Wi-Fi password), you can reconnect it using your browser.
- Use a laptop, tablet, or phone that can connect to Wi-Fi.
- Disconnect from your home Wi-Fi.
- Connect to the inverter’s Wi-Fi network (it will appear as a string of letters/numbers).
- Open a browser and type 10.10.100.254 in the address bar.
- Log in with:
- Username: admin
- Password: admin (unless you’ve changed it).
- Set STA mode and transparent mode , then click Apply .
- Go to STA interface setting → Search .
- Select your home 2.4GHz Wi-Fi and check signal strength (RSSI).
- Below 60% may cause issues.
- Enter your Wi-Fi password, set security to WPA2, and click Apply.
- Reboot the module via Device Management → Restart .
Hi Jwca_Alnwick,
Thank you for the suggestion!
I did do that procedure a while ago when I was off line with the inverter dongle and finally managed to connect with wifi (solid blue light on dongle).
The issue I have now is the inverter won’t communicate with the battery?
I did however check the settings again today and all are correct, plus signal strength was in the 80’s.
A bit of an head scratcher I know!!
Hi, I had the same problem. Working fine for 4 years. I could see the battery’s 2 x 8kw 1 x 5kw on the app. But would not charge or discharge them . I been talking to Givenergy till they went into administration. So then i had to go to the installer. Luckily they had an inverter and sent a technician engineer out to replace it. Its now working fine. The problem was the circuit board on the inverter.
handystraps2, thanks for the suggestion,when I saw you picture I was hoping mine would be the same🤣
Unfortunately, the board “looks” to be in good order.
It does though appear that that is the area I should be looking at and maybe see if I can get hold of a replacement board?
Frustrating because the communication on everything else seems fine?
Thanks,Pete
Just wondering which direction I now turn🤔
10 months without battery/inverter working and still under warranty which is useless now!
Is it possible to change an AC coupled inverter with an hybrid,doing it myself or would it need doing by an installer?
I would try replacing the inverter with another AC coupled inverter but am unable to source one,only sourced hybrid inverters,thus the question.
Thanks, Pete
Now I am confused,just thought I would check the comms cable from the inverter to the battery and there isn’t one!??
