My two Multiplus 24/3000-70/50 do not act like the White Paper "Achieving the Impossible" at all.
Here you can see my setup in action. Please notice the low low on ACin (30a single phase) and the high demand, but low SOC of my battery bank (400aH Lithium).
Please note my settings and data below.
According to the white paper, I should have ~10A AC available and charging the batteries at this point....but they just keep getting discharged.
Now, I switched the major load (A/C) off. Here is the system reaction:
Any help is appreciated.
