Hi
What is the best way to activate ac 2 out via battery percentage.

We have a system consisting of a 5kva multiplus, lynx smart bms , cerbo gx, 2 x 150/35 mppts, 3 x 200 amp 24v smart lithium’s and a orion 24-12/70 for the dc system.

The assistants in the multiplus is straight forward using the internal battery monitor in the multiplus but will this take into account for the other loads and feeds going through the lynx smart shunt and stay accurate.

Thanks
Grant

The SOC from the Lynx BMS is passed forward to the Multiplus. My Lynx and Multiplus show the same and I have solar and alternator charging.
