i am planning an ESS System in Europe/Austria. With 3xMultiplus II 5000 and Solaredge SE16K and Victron MPPT RS450/200. in general it should look like this:
I read through the Victron/Solaredge instructions, but still have some open questions:
1. Victron 1:1 Rule:
Sadly, there is no SE15K model available anymore. So the SE16K would be basically too big for installing it on AC-Out. But i think it should be somehow possible, to limit its output generally to 15kW. Then i think 1:1 rule is acceptable solved
2. Dry Contact:
If i understand it correctly, it would be sufficient to wire the first Multi K1 relay to the SE16K. If grid is lost, this relay will tell the SE16K to change to APS mode, correct?!
3. Victron grid meter and/or Solaredge smart meter needed?
I don´t understand, if a victron EM24 or some solaredge smart meter would be required or not?!
I do not have any loads or PV-inverters on AC-In. So basically the multis would not need any grid meter, correct?!
But does the SE16K need a Solar Edge smart meter? And if so, why? And which model?
4. zero feed in:
It might be possible, that the authority forces me to enable zero feed in, by an external NC contact. Would this be supported by Victron Multis?
input closed -> feed in allowed
input open -> zero feed in required
Will this work with EM24 or Solar Edge Smart meter?
thanks to everybody willing to help!
