PART 1: System Requirement 1. Calculate is the total power requirement (Wh) per day. 2. Assuming that peak load occurs when the refrigerator the heater/air con and the TV work simultaneously. Calculate the peak load. 3. Calculate the voltage of your battery bank. 4. Calculate the amp-hour requirement per day. 5. The system is required to work even if there are 3 consecutive cloudy days and the batteries must not run down more than 50%. Calculate the Ah you need to store. 6. Adjust this figure for an inverter efficiency of 93%. 7. Using the lead-acid batteries listed in the appendix, design a battery bank: - Battery Model? - Number of batteries in series? - Number in batteries parallel?
