Hello,  
I have a Multiplus II 48-5000 on a single phase (with ESS & Cerbo GX and 14,5 kWh Pylon). If I go 3-Phase, does it require to have the very same Multiplus (II 48-5000) or could it be smaller (II-3000) or be even a new Multiplus 1200? (assuming to parallel them on the DC-Side)

Regards  
Gerhard

Hi, this is all documented in the manuals.  
Systems must be identical.
