Will - Hell bent on AC300 until Tom's ABC rating of 72%. Your 87% was expected and I believe BOTH reviews. Crushed by your review Titan inverter capacity failed hugely as well. Has Titan ever fixed this? AC300 is completely customer untested. Consider new shootout AC300 vs Titan's latest model? I am TORN! Planning multiple batteries and it's a ton of MONEY for a retired couple. Please give us some guidance!
