I am not familiar with your Magnum inverter/charger, but MasterVolt & Victron models -- & I suspect most others -- are pre-configured to disconnect their inverter circuitry when V drops below a certain point: I think on my set-up, this is 12.0V....but that point is programmable by you. I would have thought 10.5V is much too low...there is something clearly wrong with the battery bank if inverter loads draw the V down to that level and you want to cut out well before that. Do you leave the inverter circuits on when you are dockside and on shorepower and away from the boat...or can/do you switch to 'charger only' mode? (I do. And I have the same house bank size as you do.)
