 The following settings need to be made in the master of each phase:
   * Inverter output voltage
-  * Input current limits.\\ This makes it possible to set a different input current limit per phase. Note that, similar to the maximum charge current, the input current limit used by the system is multiplied by the number of units in the system.\\ (This multiplication is done automatically when using a remote panel to adjust the input current limit.)
+  * Input current limits\\ (the effective input current limit is the setted limit multiplied by the number of units per phase. For example, setting a 10A limit with VEConfigure in a system with two units per phase results on a 20A limit for that phase. Being able to set a different limit per phase allows for maximum configurability.\\ \\ Setting an input current limit works differently when setting the AC input current limit on a remote control panel, for example a DMC or GX device. Then (a) only one value can be set by the user, not one per phase, and (b) the configured limit will be used as the limit per phase. The difference is due to the different use case of both ways of setting it: settings in VEConfigure are supposed to be fixed in the install and done be the installer, for example matching an installed generator. And the input current limit as set on the GX device is intended to be set by the end-user, for example on a yacht or in a motor home, and being able to set it depending on the actual shore connection - and ofcourse without having to do the maths of multiplying with the number of installed units on a phase.)

   * Country / grid code standard and other grid related values (AC high/ low values)

+Charger settings (voltage and current limits) are overridden if DVCC is configured and if a CANBus BMS is active in the system.
 A quick way to make settings in all units is the 'send to all units' feature. You'll see the option after making the changes to the first unit.
