Trying to use the parts I have available...
I have a wel-bilt #28650 12v solar panel (Max: 7 watt / 583mA / 15-17v) I have 2x 12v 7Ah sealed Lead-Acid batteries in series for 24v (from a APC UPS #APCRBC123).
I also have a number of components from the recent RadioShack closures. Various diodes, transistors, caps and so on, but nothing specific for this.
I want to make a charger from the 12v solar panel to charge the 24v battery that will then run a 24v security camera and PtP wireless station.
At current the camera is run from POE but it is tethered to a ethernet cable that is then in turn tethered to a 120v extension cable. This is no longer acceptable because I want to move the camera. Further, there is no point in having it on a wireless system if still having to use a cabled power source.
The wireless PtP device and camera are both using 24v POE (https://www.ubnt.com/airmax/nanostationm and https://www.ubnt.com/unifi-video/unifi-video-camera-g3) and I can't see any reason not to make it solar powered.
I've looked at a number of IC555 step up tripplers and a few other circuits. But they all seem to provide very low mA (as in less than 100mA). The PtP wireless device is rated at a max of 8 watts (but i'm only using it at a 1/4 of its max power output) and the camera is rated at max 4 watts.
UPDATE: assuming my meter is correct, the equipment is using 220mA with IR off (day) and 250mA with IR on (night).
This may not work out at all. The solar panel is rated max at 7 watts. So I don't see it being able to charge the battery and provide enough power to run the equipment.
Some advice here would be greatly appreciated. I'm only a beginner here but I want to learn and it's fun to build things!
