Power House!

I have been using my AC300 with two B300 and two B300K for about a year now, and all I can say is wow. Between daily use, back up power, and off grid use, this thing does it ALL! It has not missed a beat. With the right panels set up, this thing is a beast! I would not hesitate to buy another when the funds allow.
