This document shows how to configure a Victron Multiplus or Victron Quatro inverter to use external signals to turn charge and discharge on/off separately. This is very useful when using a Chargery or other BMS that has control signals for charge and discharge. The assistant can be used to build something like this:
Note: I use opto isolated SSRs for the relays.
Hooking up to the electrodaucus is even easier.
======================================
Edit: I added information on a possible workaround for the MultiPlus Compact.
Warning: The Victron MultiPlus Compact is not the same as the Victron MultiPlus. The MultiPlus Compact does not have the auxiliary input so this will only turn on/off the Discharge or the Charge, but not both. However, there is a possible workaround using the Assistant for controlling the charger and the remote I/O pins for controlling the inverter load:
To make this work the Two-signal BMS assistant should be configured like this:
Caveats:
1) I have not set this up and fully tested it.
2) With this set-up you can not use a MultiPlus Digital Remote.
3) I don't know what the switch on the front of the Compact will do if you try to use it as well as the remote inputs.
