i've set this 'sub-mode' in the past for 1 or 2 days just to verify that internal consumers (incl. genset starting) works and cause no overload conditions. My current undestanding is that that setting address 33 to 'Inverter Only' the systems works as if the grid is dead, but the grid (AC-IN) is physically connected and is alive - but ignored. Now i would like to run in that mode for a longer period (still the basic configuration is ESS) so from a MP point of view it looks like a long term grid outage - what are the implications when doing so ? Charging will continue through 2 MPPTs - daily charging is enough in summer times to compensate the nightly battery drain.
