Hi everyone. I have a trade show I need to attend in a few days. I just found out they will not have power available for me to run my lighting. I am thinking about running everything off of a car battery with an inverter but I can't seem to come up with the what run time I should expect from my setup.
Battery: Marine battery w/ 800 cca (my research says it should be about 45Ah)
Inverter: I have two. I can use a 100w or a 400w inverter both cut off at 10.5v)
Lighting Source: 120v LED bulbs - totaling 44w
My main concern is how to factor in the power that the inverter will consume in the conversion to AC and what will be lost in the circuitry of the LED bulb in the conversion back to DC. I know there will be some loss here but I can't figure out what it would be and if it is significant to worry about.
What do you think my realistic run time should be?
