Sorry to bump an old thread.
I don't own a transporter but I have an Aferiy in my work/camper van (Ford Transit)
I have an AFERIY 2001A (first edition) it's very good! It powered my dual Ninja Airfryer, fridge, full bean to cup coffee machine, and microwave with no issues.
I've also put solar on the roof and charges well from that. I'm about to put a DC to DC charger in for the longer trips or winter when there's not much sun.
The main issue that really bugs me is there's no app connectivity so no way of monitoring the system or turning it on and off. Another one is if you've got the solar plugged in all the time (i.e. overnight) and in the morning there are not enough watts coming from the panels (I think above 40 watts) it will click and run the fans like it's about to turn on but doesn't. You then have to manually turn it on or leave it click until enough watts come through.
This could be overcome by using a remote switch to the front of the cab or a wireless switch but I haven't installed one yet. I'm planning on installing the DC to DC charger with switches for the solar and van battery so that should help with the 'clicking'.
Other than that it has been a really good power station and customer service has been really helpful with any questions.
