8.7 AC-FLEX
8.7.1
General information
The next3 has an AC connection that can be freely programmed as:
• A second AC-Source, for example for
o Grid /genset in hybrid installations with grid and a generator backup that don’t require
grid connections securities.
o Gensets of different sizes for fuel consumption optimisation
o Shore connection/onboard generator for boats
• A second AC-Loads, for example for
o load shedding, non-priority loads, dump loads, etc.
o load monitoring
The choice of configuration is done at the system set up with the configuration wizard. The AC-Flex
behaviour is fixed and cannot be changed during operation for security reasons. To change the
configuration, you will need the expert access code and to run the wizard again (restart the
settings).
8.7.2
AC-Flex as source; information and settings
The information display for the AC-Flex as a source is like the AC-source when you select a genset,
as shown below.
The settings for the AC-flex as a source are the same as for the standard AC Source. It is exactly
similar for the genset connected on the AC source, so it is not repeated here (see AC-source
settings chapter 8.3.3).
8.7.3
AC-Flex as Loads; information
The information display for the AC Flex as load is like the standard AC-loads, as shown below.
