that was about one tenth the size of the state-of-the-art at the time. It had to have an efficiency greater than 95 percent and handle loads of 2 kW. It also had to fit in a metal enclosure of no more than 40 cubic inches (the eponymous "little box") and withstand 100 hours of testing. The goals of the competition were lower cost solar photovoltaic power, more efficient

. Google also hoped a smaller inverter could make its data centers run more efficiently. More than 100 international teams from university researchers and students to large companies and garage tinkerers entered the Google Little Box Challenge competition. Eighteen finalists were chosen in October 2015. These 18 teams entered the Challenge's final stretch by submitting their competition prototypes, which underwent Google's stringent test regimen. The results of this worldwide competition were announced at the ARPA-E 2016, March conference. Of the 18 finalists, only 3 teams passed every one of Google's test requirements, those being the top three finishers.
