Hello all together.
Iam about to buy an ESS System for my 3Phase Home in Germany.
I wanted to go with 3x Multiplus 2 5000.
The Batterys should only charge with PV Power not from Grid (Except the Soc is to low).
I know this is all no Problem.
Questions:
1. If one or two Phase fail, i want that the MP2 indeed charge the Battery to a set, higher, SOC, so that the MP2 on the failed Phase can go and produce the missing Phase out of the Battery.
2. I have an Inverter Generator with 18A one phase. In Case of a Powerfailure (All 3 Phases dead), i want to manually switch the GRID off and the Generator on my Master MP2. Can i somehow switch to "Gernator Mode" (UPS Mode off, Ampere Limit to 15A, loading Batterys from ACIN), without needing to reprogramm?
Like a switch that if pressed the MP2 will switch to "Generatormode".
Or do i need a Quattro for this? I dont need to do the switch automatically, but it should doable for my Wife (Turning two switches and start the Generator is no Problem, but programming the MP2 on the other Hand is...)
3. I didnt find a answer to this maybe clear question... Do i need to Fuse the MP2 to their maximal Transfer Capacity? Or can i use my already in Place 63A Fuses? (are they fused internaly?) 50A Fuses are more expensive...
