I started with a job to upgrade batteries on a GOODWE installed in 2016 by someone else. It is a lightgreen unit I have never seen before. The unit has no CAN comms but there are 2x RS-485 ports only. The 1 RS-485 is used for the energy meter and the other one is ment to connect to a battery using a GOODWE EzConverter no matter what comms are used.
I have 3 Q’s
- Goodwe do not have any stock of the converter here or in China. Will a general CAN to RS-485 do the job or do I need a dedicated GOODWE product? I see them all over the net.
2.If one can not mannage the CAN to RS-485 convertion can I try use the Pylons under ''users define"? If so, what settings will be good for the new Pylon 3000C models?
3.Lastly, I can not mannage to connect to the Inverter using PV Master so now I wonder if that unit may not have WiFi. If that is the case, how do one comunicate with it?
Any help will be welcome.
I will try to load a pick of the inverter.
