TASK 2 John is impressed with the system. But the backup time is to small. In other to increase the back up time We have to increase number of batteries. John also use a petrol generator To charge his battery when there is no power From the national grid (PHCN) John wants to spend 10 hours of charging the battery daily. If he has an average of 4-6 hours of power from the grid daily Question 1 How many batteries will be needed in order To attain 24hrs supply. Question 2 Configure the Batteries into series-parallel configuration Use 200ah Battery rating. |
