I have 2 Growatt SPF 5000 ES (Solar Inverter+Charger combined) in parallel mode. This system can deliver up to 10 kW power out (230V) in single phase mode. I have 2 solar arrays. Each array connects to it's own Growatt. Both Growatts are connected to 5 parallel connected Pylontech US3000 batteries (48 volt).
Now I want to replace the Growatts with Victron equipment, because the Growatts have proven to be unstable and unreliable the last 12 months. I need something more stable, more reliable and more professional. So I want to switch to Victron.
But there are too many different types of Victron equipment. I don't know what to choose.
So, what do I need? Apparently I need an inverter that can deliver 10kW / 230V in single phase mode. (I have two groups behind this)
I also need to connect it to the battery bank, so it must charge the batteries during the day, only from solar. (never charge from grid). Grid must be used when solar is not available and battery SOC drops below 30%.
And I need to connect 2 different solar arrays. So I guess I need 2 MPPTs.
I was thinking of a Quattro or Multiplus 10,000VA or even 15,000VA plus 2 MPPTs. But which ones?
Or do I need two in parallel mode? I don't know what's the best combination. The Growatts are All in One. But I think Victron doesn't have AIO's.
Can someone help me out? What do I need and how do I connect them (schematic) and how to configure everything?
Thanks in advance,
Mike
