Hi I had an Aurora 3.6 inverter that up and till a few weeks was working but completely died. I had this pushing data though the RS485 port to a PI and then to PVOutput.
After Auroa died I now have a GROWATT 3600MTL-S Dual MPPT 3.6kW Solar Inverter which using the shine LAN box which uses a RF dongle connected to the RS232 port on the inverter. Though with this is it does not boot up in the morning. Please note I am still trying to find a solution to this. So was hoping to use the RS485 port on the Growatt to push data to the PI and then again to PVOutput. I am also not sure if this will work while I have the RF dongle connected to the RS232 port. I have read though the threads here and I maybe missing something but I am sure the all deal with RS232 port. So will they work with the RS485 port using a USB to RS485 unit.
I have sorted the first problem with dongle and LAN box with a firmware update.
I did find this one https://fixedbycode.blogspot.com/2014/04/how-to-upload-data-from-growatt.html but it for the RS232 port. I am wondering if it can modded. So I need figure the program and running it on the RPI. Any help or suggestions are welcome. Thanks.
