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 watts running for 4 hours per night

Answer:

763.94Wh

Explanation:

If the load is 120 watts running for 4 hours per night, the energy consumed is

120*4 =480 Wh

So, the energy gathered by the PV array is

E=480/(77%*96%*85%)=763.94Wh
