Hi All,
I am in process of planning for a solar powered DC power source for CCTV and few LED lights.
Following is the list of appliances i am planning to connect.
1. 6 CCTV cameras, measured current draw from each camera is 0.25 Amps @12v DC
Total consumption of 6 cameras - 12 * 0.25 * 6 = 18 VA
2. DVR - 0.75A @12v - 12*0.75 = 9 VA
3. 3 units of 18 W Led Lights - 18*2 = 36
Total VA consumed for CCTV (24 hours operation) = 27*24 = 648 VA per day
Total VA consumed for LED lights (8hr operation) = 36*8 = 288 VA per day
Grand total = 936 VA.
My plan for panels and battery
Panels - 2 units of 12v 100W
Battery - 1 unit of 12v 100Ah
Charge controller to be a PWM based controller - on Arduiono
Please let me know if the approach is correct.
Thanks
Matt
