48? ..... 72? .... Lower? .... higher? During the day i find we typically have about 5kW's of Surplus that we would have feeding back onto the grid from our solar. Thus, since that works out to ~20amps of 240V - i set the X's max charge power level down to 20 amps - & w/in 3 to 4 hours, turning on season & drive patterns, that does the trick for our daily use & keeps the post-harged range no higher than an 80% charge. anybody else have any particular HPWC patterns? we got a $300 deal on the unit & I wired it in myself, so it could run @ 72amps in a pinch. The unit seems kind of overkill, but for those rare exceptions when we need much more charge, much quicker, I didn't want to pass it up, even though we always have enough range on hand to get to the closest supercharger, regardless whether we had north, south, or east. .
