Hello,
I have 3 Multiplus ii 5000 in parallel + a Pylon battery bank + SmartSolar RS450 + Cerbo.
I have the grid connected in parallel to all Multiplus ii, but controlled by a relay, so I use it only when I need it. The grid power is not the best, so I want to isolate our internal energy from the grid so I wanted to add another Multiplus ii connected to the Grid and the battery bank, and disconnect the grid from the other 3 Multis. So I can turn the grid only when is needed, but the 1 Multi will charge the batteries without doing the Bypass to the internal loads.
So, no loads connected to the multi as a charger (If I can connect an AC load isolated from the other Multis, will be nice, so I can have an extra power, but my main request is about isolate the external grid).
Thanks for your support,
