At a Glance
This comparison targets buyers deciding between a mid-capacity portable unit and a high-output whole-home backup system. The Delta Pro Ultra X delivers 12,000W of running power and 6,144 Wh of battery capacity, dwarfing the AC200L's 2,400W output and 2,048 Wh storage. That gap shows up in device coverage: the Ultra X powered all 53 tested devices, while the AC200L handled 43 of 53.
Solar input tells a similar story, with the Ultra X accepting up to 10,000W versus 1,200W for the AC200L, though both units reach a full solar charge in roughly 7.3 hours. Surge capacity is another major split, at 24,000W compared to 3,600W. The tradeoff is weight and portability: the AC200L comes in at 62.4 lbs, making it far easier to move than the 187.4 lb Ultra X.
Both use LFP chemistry with similar cycle ratings of 3,000 and 3,200 respectively.
