Trying to put together small system for four wireless security cameras

[wmv7766]

I want to buy a solar kit that can power four of these cameras, including with 40 hours of backup power. https://www.bhphotovideo.com/c/produ..._wireless.html

Does anyone have a recommendation on a kit that can accomplish this for a few hundred dollars?

I live in southern new mexico so lots of sunlight.

Thanks

Howdy wmv7766 and welcome to solar panel talk. First forget kits, they will supply an amount of power but chances are it wont be enough or it will be too much. What you MUST do is a loads analysis. So dig into the specs of your cameras and find out how many watts they draw, times that by hours in use per day and how much reserve you need. Once you have a daily load worked out then we can help you design a system that will work. So for example if those camera's use 20 watts each, times 4 = 80watts x 24 hours = 1920watts or 1.92kWh

The best thing is to go to the off-grid section of this site and start reading the sticky notes about designing a off grid system, its not going to be cheap, if grid power is available you will be far better off with that, cheers.

There are no kits you would want. Took a while to find the specs, but I did. The cameras use 5 watts. Daily usage = 4 x 5 watts x 24 hours = 480 Watt Hours. Assuming the panels can be placed in full sun from dawn to dusk with no shade it wil take:

Panel Wattage = 200 watts
MPPT Charge Controller = 15 amps
12 volt @ 200 AH

The battery will give you 3 days of usable reserves.

Good luck

If you're running wires to the cameras, you might consider using Power over Ethernet IP cameras instead... wireless links are not nearly as solid as wired ones. (Watch out, though; not all cameras work with all monitoring systems.)

Surprisingly, there appear to be affordable PoE switches on Amazon that accept 12v-48v power, which might make integrating with solar easier.
