Think of Assistants as apps, as on a smart phone. Assistants are little applications that run inside a VE.Bus Multi, Inverter or Quattro. They reduce the overall cost of a system: in 99% of all installations it will not be necessary to add an additional PLC (Programmable Logic Controller) to get for example load shedding, optimizing use of solar energy or automatically starting and stopping a genset.
In advanced systems you can also combine multiple assistants, it can even be useful to add an assistant multiple times. The Assistant logic is executed from top to bottom, which makes it possible to create complex logic.
To get a better understanding of the possibilities, read the list of available assistants.
VE.Bus Multis, Inverters and Quattros must be loaded with 2xx or 3xx firmware in order to get the Assistants tab. Note that running these firmware versions disables the use of the Virtual switch tab. For 95% of all Victron installations it is not necessary to run Assistants at all. They either do not require complex logic, or the required logic is included on the Virtual switch tab.
More information about which firmware type to choose for an installation, and the updating instruction, is available in our PDF VE.Bus firmware versions explained.
You will now see both tabs, Virtual switch and Assistants. On a real system there will always be one of both, depending of firmware type loaded.
Note that it is even possible to make a fake three-phase and parallel system, using VE.Bus System Configurator.
Multiple Assistants can be used in one unit. For example the Programmable Relay is often used multiple times. When doing so; this is how they are evaluated:
- an ON condition always has priority over an OFF condition - multi criteria in the ON ( or OFF ) list go by the OR principle
