 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.)

 ==== Assistants ====
-  * All self-consumption Assistants, Hub-1 to Hub-4, need to be loaded into each unit in the system.\\
+Assistants can be used to expand the potential configuration options of your system, and are required in some installation types. When using assistants with multiple units, some assistants are required to be loaded onto all units in the system individually, and some assistants are able to be just loaded onto some or one of the units.
+  * If you are using a self-consumption assistant, such as ESS, Hub-1 to Hub-4, the assistant will need to be loaded into each unit in the system individually.\\
   * PV Inverter Assistant needs to be loaded into each unit in the system.
   * The VE.Bus BMS and the Two-Signal BMS support Assistant also need to be loaded in each unit in the system.

 Tip: a quick way to load Assistants into each unit in the system is to save the settings after configuring the master in L1. Then open VEConfigure for another unit and load that file. VEConfigure will automatically adapt the Assistants for the slaves. (note: In some cases you might get some warnings. Please step through the assistant in that case.)
