C. 1.764%
D. 17.64%
Now, since the system is not connected to the grid, the family Smith will also need some energy storage. Mr. Smith has specified that, since it is a weekend house, only 2 days of autonomy will be needed. In this case, batteries with the following specifications will be used:Battery capacity = 100 AhBattery voltage = 12 VMaximum allowed depth of discharge = 50%The system is designed to use 24 V as operating voltage. What will be the minimum needed battery capacity in Ah? How many of the specified batteries will be needed? ______
