Multiplus II node red Grid set-point

Please help me with grid set-point.


I understand that feeding 'grid set-point" with value 100 will work in such a way that inverter will consume 500W and the devices on ACout will folow 600V, right?


And when I read " Venus system|Grid L1 (W)" and send the value to "Grid set-point" all the power will be from the battery?


the problem is that it doesn't matter what I send to grid to-set it just not generate flow from battery.


I spend few hours on it, checking manuals and youtube videos and it not working.

I think that in Settings>ESS should be some options, but there is only "No ESS Assistent found"


can you help me?

You need to install ESS assistant first.

Then you'd get ability to play with grid setpoint

Thank you for the answer! How to install ESS? I have the newest firmware. Is it possible to install it without MK3 cable?

Please read the manuals, this is all documented in detail in the ESS guide and is part of the basic research anyone attempting this should do.

There is also free video training on the setup on the professional.victronenergy.com site.
