Question 729526: Hi how would you write the equation for the following question?
A 7kW, 240V generator is installed in a photovoltaic system designed with two days of battery storage at 50% depth of discharge(the load uses 50% of the battery storage over 2 days) and the system is sized for a charging rate of C/10.(C/10 = 100% charged over 10 hours C/20 would be 100% charged over 20 hours, etc) Approximately how much fuel will be required per day when the generator is the only power source? The generator burns about 1.6 gallons per hour.
I know the answer is 4 gal per hr.
I would like to see how to write the equation then solve it.
Thank You for your help
Bob
