from what i've read in past threads is that the travel disconnect which is mandated by EU law can be disabled.
although, i still believe there is power for the fridge while underway if kept to the EU setting.
It comes down to what you need out of the unit, and if you need all the options.. tanks senders, solar input readings, state of charge, pumps switches eta
I ended up with using a Votronic Jupiter 100, as it allowed me to see the fresh and waste water levels, as well as protecting the battery with low voltage switch off, it monitors the solar, state of charge, internal/external temps.
Plus i had all the other votronic switches and DC-DC charger, so it all the panels look the same and data is transferred between charger, solar, and BMS via Bus ports
