At a Glance
This comparison targets buyers choosing between a mid-range portable unit and a high-capacity home backup system. The Delta Pro delivers 3600W of running power and 3600 Wh of battery capacity, doubling the AC180 on both counts.
It also powered 47 of 53 tested devices compared to 39 for the AC180, giving it significantly broader device coverage. Expandable battery support makes the Delta Pro viable for extended outages or whole-home circuits.
Solar input peaks at 1600W versus 500W on the AC180, so off-grid users can pull in energy more than three times faster per panel array. The tradeoff is real: the Delta Pro weighs 99.2 lbs, nearly three times the AC180's 36.2 lbs, and it lacks the AC180's 20ms UPS switchover for keeping sensitive electronics online during a grid drop.
