Hello,
I'd like to set up BlueSolar MPPT, MultiPlus and Cerbo GX in such a way, that batteries are used only as an UPS backup and AC load is combined from AC input and excess PV power.
Basically reducing the consumption from the grid, when/if enough PV power is available.
No feed back to grid.
Optionally some %, like 20, of power stored in batteries would be allowed to be used to supply AC loads (together with PV and grid).
Is this possible? Thanks.
