Week 14 Fyp 2 : Prepare for presentation

Week 14 Fyp 2 : Testing functionly and take the result

After making the connection on my project, it's time to see how this works. Video below shows how it's work.

From that i get the result for input/output voltage, current load, and solar output.

So, Vin(from battery) = 12.22V
      IL(Load current)   = 0.86A

Solar Output (Time versus Voltage)

Time (H)	Voltage (V)
0800	10.21
0900	10.43
1000	12.35
1100	17.63
1200	18.54
1300	18.52
1400	17.41
1500	15.52
1600	10.41
1700	8.32
1800	7.21

Current load

Calculation for charging the battery.

Battery rated 7AH

Current load, IL = 0.86A,      7/0.86 = 8.14Hours / 8H 14min (for load).

Charging time, 

Solar 12V, 10W

Solar Current, Is = 10/12 = 0.83A

So, 7Ah(battery) / 0.83 = 8.43Hours / 8H 43min to charge the battery.
