Hi,
I have the following equipments:
- SMA Sunny Boy 6kW - already connected to grid.
- 12 solar panels of 485W, already connected to SMA Sunny Boy.
- Victron Multiplus II -48V, 3000kW
- Pylontech US5000, 2 pcs.
How can I connect SMA Sunny Boy with Multiplus so that the batteries are charged ONLY from solar power?
Thank you,
Mihai
Take a look at the ESS manual:

Hi,
1. I am aware of AC coupling (AC OUT of Multiplus 2 is connected to SMA AC).
But it is not clear for me what happens when the grid goes down for maintenance purposes.
In this case the SMA must NOT send power to the grid.
But since the AC OUT of Multiplus is connected to AC it means that it will send power to the grid. Is this correct?
How I avoid such case?
2. Are there other ways of connecting these 2 devices except AC-Coupling?
Thank you,
Mihai
If your sma already connected to grid - then isn't this already set up as required? , all you need to do is connect multiplus/ set up ESS ?
As already described read up on ESS and there is a plethora of other victron documentation which I feel will help or if this isn't a viable option then I'm sure there are plenty of professional services installers that would with pleasure assist for a sum .
There are many ways to connect multiplus - ACin only(this is bi-directional) / ACin + ACout, all documented in manuals/ victron guidance documentation.
