(c) A farm house in a remote area requires on average 280 kWh per week. The average insolation time in the area is 7 h/day at a solar irradiance of 1000 W/m². A study by an electrical engineer is made to install a standalone PV system for the farm house with the following specifications: i. A set of 32 PV modules, each capable of generating 270 W at a solar irradiance of 1000 W/m². ii. iii. iv. (i) (ii) A charge controller which has an efficiency of 95% A set of batteries which have an efficiency of 79% due to losses An inverter which has an efficiency of 92% Draw a block diagram of this system and determine whether this PV system could meet the farm house demand (justify your answer). What is the purpose of the inverter in the above PV system?
