Hi,
I have a Raspberry Pi which I am using with the Venus OS. I currently have my MPPT 150/45 and SmartBMV 712 connected to it and they are providing data without issues using VE.Direct cables.
The problem I am facing is connecting my Multiplus Compact 12/1600/70 to the Pi. I thought this just used one of the ethernet ports inside the Multiplus but when I connected it to my Pi, the inverter turned off with a red error LED. I was initially worried that I had done damage. If this is the port I need to use, then I am really surprised that there isn't an external one to make things easier rather than opening up the inverter and feeding the cable out.
I realise that support for the Venus OS on the Raspberry Pi isn't really covered mainstream, but also the inverter manual does not appear to cover these two ethernet ports, let alone how I can connect anything to them. I find the operators manual severely lacking in some areas, such as connectivity but if it does exist, then no pointers are given as to where to find the information.
Is there anything else I need do? The service engineer here in the UK suggested that I change the switch 2 on the DIP switch bank, maybe, but he doesn 't know much about running with a Pi? Ideally what I would like to do is to monitor things with the connection to the Raspberry Pi and then also perhaps configure the Multiplus through the other port, if that is at all possible.
I'd be really grateful for some pointers so I can get this working without frying my equipment.
