Figure 58 - Commercially available power inverter comparison chart
In the end it was decided that Wagan 2016-6 would be used. As it turns out, the peak
efficiency of this modified sine wave inverter (90%) was just as high as the pure sine
wave inverters in our power and price range. It also boasts a dual USB output, low
battery protection, overload protection, short circuit protection, and temperature
protection. We plan to use one USB outlet to power the external outlet of the enclosure,
and the other USB outlet to power the microcontroller if possible. A brief schematic of
this inverter applied to this system can be viewed below. As you can see, it has two AC
power outputs to go to the AC receptacle and two USB power outputs to be connected
as stated above. The figure below shows a schematic diagram of how the power
inverter will be wired to the battery, the 120VAC outlets, and the USB outlet.
