Before all the MPPT crowd get their hackles up that I'm calling you a liar, I'm not, I'm just trying to show the numbers do not add up. 120 / 11.3 = 10.62v. That would require a 100% conversion factor, something not even the most ardent MPPT supporter will try to propose is possible. I'm guessing your battery was not down to 10.6v when you saw this 11.3 amps so that makes the calculation even more beyond possible reality, so something doesn't add up does it. The catch cry that lithium batteries are not magic must be the same for MPPT controllers, so either the solar is not 120w as the labels claims (6 x 20), or the unit being used to measure the current isn't accurate, or a combination of the two, or magic is a foot.
