I have a 5kW inverter with WiFi module and I'm not able to get any data and there are no information around. No way to get data from the wifi adapter except from via Solarman that anyone could figure out. Quote Link to comment Share on other sites More sharing options...

Thanks No internet on the place, furthermore what I tried about Solarman is a shit. It has random acknowledge frequency about 10 or 20 minutes.

Denarius Posted November 3, 2021 Share Posted November 3, 2021 Hi Guys, my SunSynk firmware was upgraded to comm e41c and mcu 6006 which has caused the RS485 port to stop responding to modbus requests. It now seems completely unreadable. Did anyone else upgrade and get this issue? Quote Link to comment Share on other sites More sharing options...

You should log a case with their tech support for the modbus issue. Quote Link to comment Share on other sites More sharing options...

Correction it's the 8kW, was thinking of MPPT array. I see there is a topic for this problem. Quote Link to comment Share on other sites More sharing options...
JuanH Posted November 4, 2021 Share Posted November 4, 2021 I've removed my WiFi dongle, just incase SunSynk decides to mass push this update out, in a ploy to get everyone to use their new cloud platform... Or maybe I'm just paranoid Quote Link to comment Share on other sites More sharing options...
new2solar Posted November 4, 2021 Share Posted November 4, 2021 Had the same issue recently and implemented these settings (Modbus SN changed to 00 changed it to 01). It is still working. Sc00bs 1 Quote Link to comment Share on other sites More sharing options...

It now seems completely unreadable. Did anyone else upgrade and get this issue? What you have experienced as a bug is actually a feature. This firmware update allows you to read parallel inverters with a single RS485 adapter. Previously if you wired all the RS485 cables together and requested data on modbus address 1 all the inverters responded at the same time causing a corrupt response. You were forced to use an RS485 adapter for each inverter. With this update you can query the specific address you want a response from and only that inverter responds. This update is going to be disruptive since most inverters have their address set to 0 and many modbus utilities won't even allow querying on address 0. A changelog would have been really helpful.

For the hybrid Sunsynk I would guess 150, but have never tried this. I've used 79 which is the grid frequency, which also shows a grid failure: https://github.com/kellerza/sunsynk/blob/main/sunsynk/definitions.py#L35 Quote Link to comment Share on other sites More sharing options...

finch6 Posted November 16, 2021 Share Posted November 16, 2021 Firstly... Congrats and thank you to @Bloubul7, @Sc00bs & @jacauc...! The work you have all put in is incredible...! You all deserve breweries, not just beers!!! I've been following this thread and am about to get myself a inverter/battery set to carry me through the on going load shedding - and hopefully upgrade to PV once the pocket allows I've already got a Pi Zero running Node Red and added the flows from @jacauc's GitHub page... Thank you!! I'm now looking at the connection from inverter to pi... Seems I was at the back of the queue as all the RS485 Pi Hats are sold out... Anyone have a spare one lying around up for grabs or know of where I can get one?? Wave RS485 HAT For Pi Thanks again everyone for all your contributions and comments, almost makes this setup basically plug and play!!

Thanks for the info @JuanH, really appreciate it... Was kind of looking forward to the DIY part of it but if I can't get my hands on a DIY setup, at least I have other options, thanks again Quote Link to comment Share on other sites More sharing options...
