For next1 inverter-chargers:
Every next1 has the equivalent of the nx interface displayed as a web interface via the Studer monitoring application. This is the default and cost-effective way of setting up and controlling the next1, and the alternative to a dedicated physical screen. It can be viewed from your phone, tablet and pc and works with or without the internet: the next1 inverter creates its own access point.
For next3 inverter-chargers the nx interface is mandatory to configure your system.
