Lost contact with one battery, but now two???

[tonyvfield]

Hi, I am hoping this is the right place to get some help. I know very little about HA so please make your answers and help in simple terms.

I have a plant setup with 2 inverters and 2 batteries. The system was running fine for many months but since august HA cant see one of the batteries. The inverters are on static IP, I have done a hard reset on the inverters, power cycled the router but to no avail. I have check the Static IP address and they match what HA finds. Initial as you can see from the log HA find both inverters but then the subsequent actions fail on inv2. INV1 is still working.

Likely this is the inverter and GivTCP not talking to each other.

On the inverter that GivTCP is not able to read, try doing a 'reset to defaults' on the GivEnergy portal, this can often cure such 'not talking' errors.

An alternative fix is to delete all the PKL files from /config/GivTCP and restart the GivTCP add-on

Hi, I have reset the one inverter that was playing up by using the portal. No change. Please next idea.

There is a missing serial number in the log. Does that give anyone any ideas? File "/app/GivTCP_1/mqtt_client.py", line 386, in on_connect client.subscribe(MQTT_Topic+"/control/"+GiV_Settings.serial_number+"/#") AttributeError: type object 'GiV_Settings' has no attribute 'serial_number' 2024-09-11 11:59:49,651 - Inv2 - mqtt_client - [ERROR ] - No serial_number found in MQTT queue. MQTT Control not available.

Just a silly question - have you confirmed that the GivEnergy App and web portal can see both batteries OK? I only ask as I had the issue that batteries were loosing communication with the Inverter after overvoltage alarms that they weren't properly recovering from.

[tonyvfield]

Sorry, I should have put that in. Yes the App and the web portal can see and manage both inverters. I have checked with GE and both inverters are on the same software and firmware. They dont see any difference between the two.

Try deleting the PKL files and restarting GivTCP?

What version of GivTCP are you using ?

[tonyvfield]

I have deleted two pkl files. it was all I could see. I have restarted Givtcp I get the following trace 2024-09-11 19:57:06,543 - Inv2 - read - [ERROR ] - 10 failed inverter reads in a row so removing regCache to force update... 2024-09-11 19:58:35,942 - Inv2 - mqtt_client - [ERROR ] - No serial_number found in MQTT queue.

I now have lost contact to both inverters

Hold on for 1 hour please. The last set of mods seem to have kicked it into life. I also switched the 'old solftware' on and off and I think things are starting to work. But I want to see if it stays working

[tonyvfield]

Yes its working. Many thanks to everyone. I think the thing that sorted it was deleting the PKL files.

What a star you all are.

[gcoan]

Glad to hear you got it sorted 👍
