This Video shows how to set up a “mini solar power system” which will run small lights, fans, air compressors and other low power AC and DC items. This will also charge most electronic portable devices (tablets, phones, laptops). consists of one 15 watt solar panel, one 12ah battery and a 70 watt inverter. The system will also charge rechargeable AA AAA C D and 9V batteries (using standard battery charger). Note that most items shown in video can run for several hours on the one battery. To run larger items add another battery to it (just hook it in parallel).The total cost is about $100.Great starter system !!
