Switching from grid to generator with Node-RED

Node-RED
,

When I want to connect my generator to AC1 of the MultiPlus units in my three-phase ESS via a changeover switch, I change the following settings in the console.

1 - I lower the maximum input current of the MP2,

2 - I switch ESS from Optimised with BatteryLife to Keep Batteries Charged,

3 - I change AC1 from grid to generator.

To do this via Node-RED, I need three Victron Nodes and a few standard functions.

1 I can do this via VEBus System Control, system MP2, Measurements, input 1 current limit

2 I can do this via ESS Control, Venus setting ESS state

3 I can’t find a node that lets me switch AC1 from grid to generator…in the example video I can see that Settings Control is being used, but that doesn’t offer the Victron Settings. Can anyone help me?

Thanks,

Hello @NicovH ,

You can use "Custom Control’ node to change all needed parameters.

Pls mind you cannot change grid code of your MP2. It might nit accept a normal generator.
