One thing that everyone probably already knows but might help a new person, that is that your battery voltage to determine charge state is with a resting disconnected battery. If your inverter is on and your battery voltage drops to 11.8 when the inverter kicks out your battery will probably recover to something over 12v. If you have your system set to start the generator at 12v you are most likely only down to 70% charge. If you need the most time from your inverter set the system to start the genny at the same time your inverter kicks out. You will still not be below the 50% discharge level and your starter will not be competing with any load from the inverter as the load from the starter will drop the voltage to inverter kick out if it has not already and as soon as it starts the inverter will come back on line.
