Nice Install. Curious to know which comms cable did you use between the inverter and the battery? Thanks

Hi Wannabe i don’t have a contact at Solar-Assistant but have setup and using 2 x Pi Zero’s and 1 Pi 3B to run solar-assistant and monitor Kodak Inverters and Pylontech batteries. If I can help let me know.

Hi Kortsluiting I’m not familiar with the batteries but I see that they mention monitoring via an app that connects via Bluetooth to the battery. I would check the battery SOC using that app instead of the WatchTower app to be certain that you getting the correct SOC.

Hi Steve, keen on knowing your setup and what are you using to monitor it. The graphs look great.

Hi, not sure if you found one but Communica seems to have stock. Good luck

Yes I get 225 volts on AC-in. The inverter shows 0 volts at AC-in. You are correct. We have tried pressing the black button on the breaker but nothing happened. Is there a certain order to follow or length of time it should be kept in?

Would this stop the inverter from detecting the grid connection?

I will check this. I know there is a 40A circuit breaker at number 10. Not quite sure how this circuit breaker works though.

Morning Curious to know whether you've sorted this and how. I'm having a different issue but would like to follow up just in case it resolves my issue too.

@Steve87 I think you missed this. I have a bigger issue than the battery pairing now. The inverter does not see the Grid connection at all now. 😔 Not getting any replies from Segen Tech even though I've logged a call and spoken to them directly.

So, An update from my side. The problem was as Segen told me an incompatibility between the battery firmware and the inverter firmware. They downgraded the Secondary CPU Firmware and the communication worked. Then everything seemed to be working fine until I connected a raspberry PI with SolarAssistant as a better visual monitoring system. After this was connected however, overnight the Inverter failed and switched off WiFi and the USB port. Segen then told me that the USB port is not for monitoring and that Is should buy an R232 port to connect the PI. I did this. However, after this was connected the inverter stopped detecting the Grid connection. Even though there is 230V on the AC input cables to the inverter the inverter doesn't detect the Grid connection at all. No errors no warnings no flashing lights. The inverter supplies power to the loads from PV and battery and the PV charges the battery. It just does not detect the Grid. Segen and I are at a loss for what else to check. So any assistance would be appreciated. Been through the following trouble shooting steps. No flashing LED though.

Morning, still don’t know what to do now. With USR settings the inverter does not manage the battery. Hopefully Segen will get back to me today. The versions from the WatchPower app below.

Thank you. I did try the RS485 port with 1 dip switch on both settings no luck with provided cable or my own hopemade cable. I even tried it with a pylontech cable as recommended. No luck. Reason I listed the CAN connection is this is what worked on the OG-Plus.

The setup 1 x Kodak OGS5.6 inverter 6 x 545 JA solar panels 1 x Pylontech US3000C battery Using Comms cable supplied with inverter connected to BMS port on inverter and CAN port on the battery. I know this cable works as I’ve previously used it with a Kodak OG-Plus 5.6 inverter to the same battery. Inverter settings 01 = SbU 05 = PyL All other settings are default Firmware version 52.00 Error After switching everything on as specified in the manual. The manual states that after 1 minute or longer the battery icon should flash to indicate successful communication. This doesn’t happen. After about 3 minutes the inverter starts beeping, flashing red and displays the error 61. What I’ve tried A different cable, same error. The cable that came with the battery, same error. To use 05 as USE with settings specified somewhere on this forum, same error. Questions Anyone know what the latest firmware version for this inverter is? If it’s later than 52.00 where do I get the latest? Any other suggestions in trying to solve this issue?
