Hello Anson Guo, I’m glad you’ve joined our discussion.
I can tell you my individual and honest opinion. I bought WVC because I saw a lot of videos regarding WVC, like fixing problems, inside componentes and mainly because of our topic. I mean, APsystem uses zigbee, why not choose an inverter that has 25 year warranty. Because we want to know, we want to build, we want to do our own way.
I’m not comfortable to buy a modem that is almost the price of the inverter just because I don’t know the protocol. In other words, if you found this topic you may know that people here already have a raspberry working with emoncms and nodered.
The way I see is more or less like an IP camera. There are a lot of Chinese brands of ip camera’s that use V380 app. It just don’t work for everyone. Myself included. To solve that problem, they started to distribute a patch, for the ones who ask, in which you can free your camera. They’ve noticed that they were loosing potential professional clients.
I just have two panels at the moment, but I’m intending to grow it. Thus, I need to monitor the micro inverter to check if it is suitable. Besides that, last time I’ve imported a WiFi device, my local custom sent it back. There is another potential risk there and why I’m avoiding it.
I will try and report latter. I also noticed that they’ve reduced modem ID size to 4-characters.
