Welcome Marek! You typed your first post a bit too quickly for the system after registering, so it flagged you for approval. You won’t see this happen again.
If you intend to control the Multiplus charging (from ACin) you can use the Custom Control Node - Select your Multiplus from the “Custom” list and then Dc/0/MaxChargeCurrent to adjust charge level.
I’m a software developer, but red node in victron is a disaster for me:( I don’t understand relation between panel settings, and it influences for red node.
Currently, even my previously worked functions stopped working:(
Currently, status is float and nothing is working
I use set point to power from my battery to critical loads and support my home grid ( if inverter power is enough)
it worked only when I send negative values, to switch off “AC Power L1 setpoint” I sent value “NaN”
but above function stopped working after changing some options in the panel, unfortunately I don’t know which one, but I believe I will repair it.
I would like to charge battery when power is cheap, or I have power from PV.
It’s look simple, and I expect few hours to understand system and program it, but I completely don’t know how to manage it
Is there some clear documentation how to use nodes, and what is the relation between panel settings and their functionality?
I changed many options but finally helped me restart, but!
not restart in Settings>General>Reboot?
But [yourDeviceName]>Advanced>Restart VE.Bus system helped me
it temporarily switches off power for critical loads but really restart red node
I am also using Node-RED for customized control of my system.
I am not quite sure if this is comparable, since in my configuration I am using a Multiplus-II combinded with a Victron MPPT as a solar DC charger.
I have two additional PV inverters connected on the AC-out (in total 5kW on the MPPT, 3kW on the inverters via AC-out).
System is configured as ESS.
If I want to charge from grid, I do not only set the max A for charging, but I also have to set the minimum SoC of the batteries.
Did you take this into account, or do you have the possibility to manipulete the desired SoC directly?
For my ESS I am using this node:
