In this video I show a practical case that contains the entire universe of connection possibilities of a Victron Multiplus II and all the possible connection combinations between Victron and a grid inverter, without forgetting that you can also have perfectly synchronized MPPT's direct battery chargers. With this video I want to clarify all the doubts about the connection of a solar installation that combines a grid inverter and an inverter / battery charger. What are the differences between AC IN, AC OUT, what happens with a blackout, how to make the electrical diagram, the bypass with both the Hager SFT440 and the SFT240, I want to clear up all your questions. I am talking about my case, I have a Fronius Primo 8.2 kW with 24 panels (Longi 450W) east/west configuration (12+12) placed in AC IN and a Fronius 5 kW with 17 panels (350 W) South configuration and a Victron SmartSolar MPPT 150/85 tr VE.Can MPPT Charger with 6 Ja Solar 455W panels in west configuration, in series/parallel 2+2+2 (maximum charging capacity 85A) All this managed by a Victron Multiplus II of 5kW and 70A charging capacity. The battery is a homemade Powerwall configuration 14S 245P with recovered but high quality Samsung 18650 batteries, with an approximate average of 2.5Ah per cell. Total capacity, theoretical approximate slightly above 30 kWh, of which I consider around 20 or 25kWh real useful and usable. The management and control of the battery is entrusted to a Batrium 4 BMS that is directly connected to the Victron Color Control GX device by means of the V Can cable, in addition to the critical fault relay output that governs the TYCO emergency cut-off circuit breakers and with another relay also remotely switches off the Victron MPPT charger.
