Correct, it is an inverter/charger. Well, if i'm running the generator, i wouldn't want the inverter/charger to cut out, i'd rather have the solar panel cut out if anything. How can i determine if this will happen?
If the solar panels are providing enough charge power to hold the battery voltage above what the inverter/charger would be charging at, it makes no sense to want the inverter/charger to supply a lower charge, consuming generator gas to do so, than to take the free greater charge from the solar panels. In a way, it's like what is powering your vehicle when you're descending a steep enough hill; gravity makes you go, and the engine "cuts out" (on a modern fuel injected engine, it literally will cut off all the fuel to the engine and it's only gravity making it spin around). It would not be very sensible to suggest that you really wanted the engine to make you go rather than gravity under those conditions.
Actually "cutting out" is perhaps a bit misleading. They both contribute to greater or lesser degrees, possibly reaching all one or all the other, depending on how much power they can supply and what the battery voltage (the charge voltage) actually is at and what their programmed charge cycles think is going on. If you want to you could setup the solar controller to have a lower charge voltage than the inverter/converter, but that would also affect how effective it is when the generator is not running.
