Am looking at installing a solar system that uses solar during the day and blend power from the grid and battery bank at night. Looking at 15KWp system. The property is on 3-phase.
1 - Do i need 5kva Victron inverters one for each phase? should these inverters be single phase or 3-phase?
2- Or should i get a 3-phase 15kva inverter to be shared by all three phases?
Power blending for the whole property is key during the day and night with solar being prioritised.
If going the Victron route an inverter is needed for each phase unless there is a new 3phase inverter that I don’t know about.
They all need to connect to the same battery bank, and need a single GX device (if you were thinking about using 3x easy solars... ie if you do you’d need to disconnect the GX from 2 of them and link the multipluses into the remaining one... *not recommended*)
@Lgadzikwa, @misullivan is correct, you would need 3 compatible Victron inverters configured for 3-phase operation.
Please see the Parallel and 3-Phase VE.Bus System Manual for more information as well as further helpful links to other Victron documentation about this.
