Hi all, I have the following setup running at home: Multiplus-ii 48volt, venus GX, MPPT150|100 with a 100aH Lithium battery and Solar panels. How do I setup my system to only run from solar and battery and only use the grid when there is no solar available? Currently it is feeding from the grid continuously and only uses solar or battery when the grid drops. My SoC is currently set at 80%. and optimized without batteries option.
