Smart 'idle' algorithm ideas

Node-RED

Hi all,

My 3x Multi RS installation constantly consumes about 50-70 Watts idle and pulls a little current from the batteries. It’s not bad but can be improved.
If I put my system in ‘passthrough’ mode or e.g. limit the charge current to 0 W and disable discharge, the idle consumption drops significantly to 10-20 Watts.

I don’t think the Multi RS has a native low power mode. So, I’d like to implement a NodeRed algorithm to control this.
For example, if the DESS is not active and there’s no solar, I would activate the ‘stand-by’ mode and deactivate it if one of these conditions are violated.
Also, I wonder if such a logic conflicts with immediate switch-over to emergency power if the grid is lost or I have to take care of this separately in the code.

I’m curious what others have done to tackle this and if there’s any lessons learned, but I couldn’t find much about it in the NodeRed section here.

Thanks and cheers!

Consider checking implementation from Profile - podarok - Victron Community - details available on his YouTube channel: https://www.youtube.com/watch?v=IDZmghD-RbI

Will check it out! The youtube video doesn’t seem to have a translation available but I’ll try to reverse engineer what he’s doing. Thanks.

Very interesting concept, im interested to investigate this topic.
