Solar panel system shutting down
Posted on 2011-10-18
I installed a solar panel system to run 16 surveillance cameras.
This is my calculation
1 DVR - 15Watts = 12Volts * 1.25 AMP
16 cameras = each camera use 12V with 0.3 AMP, so 12*0.3=3.6Watts * 16 cameras = 57.6
Internet device -> around 15 Watts
So per hour we need 15(dvr) + 60(cameras) + 15(internet) = 90Watts per hour
Now this is the tricky part, we need to run the system 24 hrs
So, we need 90Wats per hour * 24 hours = 2160 Wats per day - This is what we need to keep the system runing per day.
Solar panels, we currently have 2*45 watts and 4*100 Watts 12v solar system, that generates
490 Watts / hr
5 hrs(sun power per day) * 490 = 2450, enough to recharge 2160 used per the system
again we need batteries to support a demand of 2160 watts a day, but if we have 2 days with bad weather and no sun, the battery bank should support the double(mostly everybody use 3 days)
2,160 watts * 2 days = 4,320 Watts divided by 12 V(batteries comes in 12 V) = 360 Amps
Batteries comes 12Volts 105 Amps
So we need 4 Marine Batteries Deep Cycle 12V 105 Amp
I have 8 marine batteries 12 V 115 amp.
The system shut off after 2 weeks, what am i doing wrong?
what do i need to change or add.
I am a rookie on this and have invested a lot of money on thsi system?
I am also using a 45 Amps charge controller and 1200 W inverter.
can the inverter run continuosly?
