Hi Todd, Wrenches, The XW does use an intelligent algorithm taking input data from all charging devices and the battery voltage to come with an estimate for the battery state of charge. This is pretty good, but agree an amp-hour meter would be a nice addition to get even more accuracy on this. Needless to say this has been looked at closely in house and all the hooks were designed in to add a system A-h meter module...we need to figure out when and how we can best add this. No definite answer yet, but all input appreciated.
Cheers, Mark Mark Edmunds Xantrex Technology Inc. I wish they would address the question I asked about why they neglected to include an amp hour meter that communicates with their charge controller on a battery based system. Todd
