    If a company has 1500 watt inverters in their trucks, what appliances, refrigerators, microwave, tvs, etc can I use at the same time? To my understanding, if I have a refrigerator plugged in, I would have to unplug it every time I wanted to use either a coffee maker, electric burner/griddle or tv, correct? the appliance used should total about 1/2 of the inverters wattage? If I keep the fridge plugged into the inverter, then basically I cannot use another appliance at the same time? Am I correct, or confused?

    You are correct. You can't use everything at once.

    The fridge will not use a lot of power once started but start up current is high. The same goes for microwaves, there is a spike in current needed to get it started.

    There is also issue with things that are inductive loads, like coffee makers with some inverters.

    My suggestion is to get a large one, pure sine wave inverter, maybe 3000 watts. Your fridge will be happier.

    Remember that there is an inverter overhead to run the inverter. cheap ones will had as high as 10% of the available wattage.
