I purchased an EAGLE 2 DTC 12 V and an Iota Engineering 15 Amp inverter to control my 4 panel array. It is simple to operate and rugged in its construction. I especially like the BIG backlit digital display. Easy to see in a dark corner! No fancy button pushing needed. A bich help for those of us who can\'t work digital watches. It is the IPOD of DTCs. Simple, clean and rugged.\r\n\r\nI could not be happier with your gear at AltE.\r\n\r\nKeep up the good work\r\n\r\nTim Croft \r\nSchodack Landing NY
