Finally getting some numbers from Portland General Electric about my home backup system. While the system is meant for power outage safety and convenience - I am also using it to time-shift much of my mid-peak and on-peak usage to off-peak. This is saving $7 to $10 a week on the electric bill.
Running two MP2s in split-phase with Ruixu batteries. Using nodered to manage the time-shifting.
First, I am not the person to ask. I figured what I should have from reading the Victron manuals and then verified my findings with an experienced solar & battery system installer and an electrician in my area. I did my own system design and setup but the everything was double-checked by others before being powered on and the grid connections were all done by an electrician. What I do have is fuses in the the Lynx Power-In and Distributor and also a quick disconnect on the positive between the batteries and the Power-In.
