Question:

A PV battery system has an end-to-end efficiency of \(77 \%\). The system is used to run an all-AC load that is run only at night. The charge controller efficiency is \(96 \%\) and the inverter efficiency is \(85 \%\). How much energy will need to be gathered by the PV array if the load is \(120 \mathrm{~W}\) running for \(4 \mathrm{~h}\) per night?
