sorry about the delay in responding
Regarding the N-G issue - I just ran a cable directly from the eskom side of my DB main CB to the inverter - by passing the house EL. that solved the issue,
I have a must ph1800 - 3024. was not my first choice at the time (2019) Never had any issue with it.
I would like to get some data from it. I see you can buy a usb wifi dongle but my inverter only has a usb-b (printer) & RJ485 ports.
must wifi dongle
would it possible to connect this wifi dongle via an adapter cable? or any other method?
thanks
