Thank you for the response. I have tried the settings you suggested and i'm still getting timeouts every second message or so. Frustrated I bit the bullet and upgraded the Raspberry pi from a Rpi 1 to a Rpi 4. This has yielded a noticeable improvement but still I am having the intermittent connection. Just to confirm I am not using the RS485 port as my battery is using the port. I pulled out the Rs232 dongle and using that port instead. The only other thing I can think of is to try and buy another Rs232 to usb converter. If you have any other suggestions I would really appreciate them, thank you all so far for the support!

Good evening, is it at all possible to share your settings for the timestamp, delay and "inverter" I have a very similar setup to you but getting allot of timeouts. Kind regards

Hi Ryeman, I dont have my modbus running yet but I did also receive an update on Sunday morning @ 04:00 21/02/2021. I have noticed that my versions are as follow: Version Information Protocol Version：V0.2.0.1 Control Software Version 1：V3.8.7.6 Communication CPU Software Version：VE.4.1.5 Does the Control version have an impact maybe? Regards

@Denarius Thank you for the reply, Damn it's a shame that it would not work in that way then. Yes my Wifi/RS232 port is occupied with the Solarman wifi dongle but I hate that it takes so long to update(although 10 min is not so bad). I think I will remove the Wifi/Rs232 logger and get one of those cables you posted(Thank you for that 🙂) and go down that route Once again thank you to you and the forum for the help! Kind Regards

Hi everyone, Thank you for a great thread so far. I have a Sunsynk 8kw inverter with 4.8kwh First National Li-ion Battery Module. The inverter and battery is connected using the RS485 port. I bought a USB/RS485 dongle and want to know if I can plug it into the batteries Rs485 Port as it has two. Will I still be able to talk to the inverter or will the fact that it is connected to the batteries not work? Thank you in advance
