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.
I think ESS is what you want.
Have read about ESS to but still don´t know if a multiplus II can mix like 2300W from battery AND 2000w from grid making it 4300 usable Watts .. ??
It can absolutely do that. If i set AC input limit to 5 Amps on my Multiplus2 and start a load which draw 10 Amps, It will automatically enter PowerAssist mode and facilitate the 10 Amps syncing the inverter with the grid and combine 5 Amps from grid with the rest from the batteries/solar. This function is fantastic and I use it all the time.
