Thats really cute. But in dire time of need, will it run anything of value ? Of course not.I have a 13-watt solar panel connected to a battery-pack with 400watt inverter. The solar panel sits inside my house in a south-facing window, connected to the battery-pack charging it up.
I have been playing with the pack for a while now - I can use my electric-comb to style my hair with it and it doesn't even pull 1-watt of power and doesn't drain the main battery at all by the time my hair is combed.
I have used it with my blender to make blender-drinks, it pulls about 450-watt, but, doesn't shut-down the unit, so, I am still within its limits.
I have used it to make muffins / cookies / cakes by powering my MixMaster. Heavy dough makes it bogg-down a bit, but, it works very well for cakes-batter.
It does take the panel significant amount of time to recharge the battery-pack when I reach the bottom of the available-power, but, overall I am happy with it.
Expanding the power capability (more batteries, bigger inverter) would really go a long way with being able to power larger pieces of equipment, but, I would loose the portability ... a toss-up there.
Pictures below of similar solar panel and power-pack that I have (stolen off the 'net).
Perhaps I'm wrong, but I don't think that's entirely his point... I would guess this is more of a learning experience and proof of concept. Plus it's portable. A roof or pole mount system might attract unwanted attention in "dire times". While a portable one could be put away until things settle down.
Yes, it would probably run it ,,,,, for about 15 minutes. I have lived off the grid entirely for 16 years on solar and wind and started with just one 80 watt kyrocera panel and two batteries. I have learned what you can do and what you can't do , and an elec blanket is way beyound my means and always will be. My refer only draws one amp more then the blanket, and is far more important.:hmmm: 12 volt electric blanket can save your life & draws only 50.4W (4.2 amps) :congrat:
Actually, it does very well for what it is. This one can run small electric motors (Dremel, blender, drill, etc), runs 12-volt and 120-volt lights, has a built-in air-compressor for filling tires, has a booster-cable to restart dead vehicles, can charge / run small electronic devices (laptop, cell-phones, MP3-players, I-Pad, I-Pod, etc).
I also have an 80-watt panel to two batteries (like your original setup) to run my camping trailer with plans to expand that system with a 5,000 watt inverter and two more batteries and an additional 120-watt panel (for 200-watt of solar generating).Yes, it would probably run it ,,,,, for about 15 minutes.
