Friend wants to put up a weather station in a location where there is no power. Need 9v @200ma to run. Comes with a small 120v step down transformer........like a cell phone charger more or less. I'm thinking solar charger of some sort. But I don't know wheather to go with a 12v batt and inverter, or just 12v and step down to 9v. ...w solar charging the 12v batt. Got ideas??, TIA john
