TriLife Posted June 18, 2022 Posted June 18, 2022 Greetings from Colombia, I have a Polisy Pro. I also have a Sol-Ark 12k hybrid inverter, which has an RS485 port used to get live data out of the unit (they also have an IP connection via WiFi dongle, but it is locked up and only delivers data every 5-8mins anyway). There's a company out of South Africa (https://Solar-Assistant.io), which has developed some RPi based software, using a USB-RS485 dongle to extract data out of the Sol-Ark. My question: Can I use the Polisy's USB port for this application? I'm guessing the software will need some adaptation... Cheers.

Let's see, what they say. Hopefully they'll get interested and port their code. My question was more on the hardware side: the Polisy's USB port is available, correct? There's a ton of code on GitHub, that does manage to extract data from the Sol-Ark and other inverters. Cheers

Cheers Just for reference, there are PG3 node servers for other inverters already so it's certainly possible to create one for Sol-Ark. I believe all the existing node servers get data either from the inverter's cloud service or locally over the network. I'm not aware of any node servers that use an rs-232/USB link. You can use a USB hub with Policy if you need more than the 2 available ports. One issue will be that I don't believe node servers have permissions to access the USB ports so that's something that would need to be worked out with UDI to modify the Polisy configuration to allow that. 1

Thanks @bpwwer, That's good good information. Solar-Assistant offers an MQTT link already. Given my limited knowledge at this point, it will be easier to put an RPi with their software next to the inverter and get the data that way. I know Sol-Ark is working hard to improve their data connectivity. Cheers.
