Can anyone tell me why signature solar would exchange a EG4 6500 for the new EG4 6000 xp? What’s it in for them by doing this? Yes I need to pay extra for the EG4 6000 but no freight to return the EG4 6500. Other than the cost do you see any reason I shouldn’t go ahead with the deal because it seems to be a good upgrade? Thanks everyone great forum.
