Kevin, thank you for comment, but I changed my mind about the solar generator from Solutions for Science. With card in hand I called to order it. Two days later I get an e-mail that the unit I ordered is good but for money I could get the best one. I don't like that sales tactic. I am a salesman for a lot of years and I despise the bait and switch sales tactic. Since then I have been searching and just found "BE PREPARED SOLAR". The company is in Salt Lake City, PREPAREDNESS MECCA. This unit is 5,000 watts and total is about $1400.00. Also you can add panels to get faster charge. It comes with two - 100 watt panels. Am still looking into it, but it looks great and much more wattage. They also have 10,000 watt units. More later. BOBT
