Voltronic and CAN-BUS with WECO or SOL Settings?! #245

Open moscito1010 opened 9 months ago

moscito1010 commented 9 months ago

@stuartpittaway I learned that some Voltronic models such as the King and MAX series use WECO and SOL (Soltaro) CAN-BUS in the BMS setting. I checked the hardware on my 3 devices and they all have the CAN-BUS chip integrated in the removable control panel, right next to the RS485 chip.

If you are interested I would try to get the protocol information.

Sure, see if they publish any documentation on the CANBUS protocol - a lot are simply copies of the Victron or SMA CAN BUS protocols.

@stuartpittaway I first looked for the direct route via support and am still waiting for an answer.

Do you know these things? Wouldn't that be a good additional solution for devices with Modbus and/or serial interface? My Spanish Modbus colleague with whom I exchange ideas bought a “thing” like this. Basically a tempting idea to work with the dongle. Theoretically this is a translator if I understood correctly. can2modbus

@moscito1010 sorry for the slow reply, didn't realise you had responded.

I doubt that the CAN to RS485 adapter would work without also knowing which registers/protocols you need to "speak" with in the inverter.

So we would still require documentation or working examples of code talking to the WECO/SOL protocol inverters.
