Good day,
since one week I search fir a solution fir a new customer, but I do not find the right resources on the Victron Website (orofessional).
My customer has pritty much the same Off-the-Grid setup like me:
1) SOPzS batteries 90kWh @24V
2) CerboGX
3) 2 MultiPlus 24/5000 parallel
4) 3 SmartSolar MPPT 250/100 (3,1kWp each with 10x310Wp)
5) 1 iSta-Breeze i2000/48 + MPPT
6) 1 iSta-Breeze i700/48 + MPPT
7) 1 Windmill "Brown" 3,5kW 230V AC coupled.
Now he got the offer fir a Grid-Connection with extreme good conditions including Feed-In 15kW.
However, the two Multi-Plus (model 2019) create some problems with a singel phase feed-in and we want to replace it with 3 newer MultiPlus-II 24/5000/120-50 to make a 3-phase system. The Braun windmill should stay on L1 AC coupled.
I search for resources how to configure the new system to archive a mostly symwtric feed-in, hence in daytime, if the Brown windmill is producing energy and also the Solarpanels, the solar feed-in should be mostly directed to L2 and L3.
OK, the best option would be two small 3kW Fronius Primo on L2 and L3, but this changement would be our last option, since many things woul need to change. Also maybe an increase of solarpower by 1kW per phase.
Any suggstions?
