I'm so happy right now, I'm like a giddy little school girl. At this moment we are getting 20amps from the solar panels. We are getting 10.5 amps positive into the batteries to keep the batteries in Absorption. Which means I am powering my laptop, modem, external HD, and our Fantastic Fan, all free from the sun and have been for approx. 1 1/2 hours. Don't get too critical as the numbers changed a little between my taking the pics.
