Capacity
Delta Pro Ultra: +4,096 Wh (+200.0%).
This comparison targets buyers deciding between a mid-capacity portable unit and a high-output whole-home backup system. The Delta Pro Ultra delivers 6,000W of running power and 6,144 Wh of capacity, tripling the AC200L's 2,400W output and 2,048 Wh reserve. That gap shows up in device coverage: the Delta Pro Ultra powered 52 of 53 tested devices, while the AC200L handled 43 of 53.
Surge capacity tells a similar story, with the Ultra hitting 12,000W versus 3,600W for the AC200L. Solar input on the Ultra tops out at 5,600W, nearly five times the AC200L's 1,200W max. The tradeoff is weight and bulk.
At 62.4 lbs, the AC200L is roughly a third the weight of the 182.1 lb Ultra, making it far easier to transport for camping, tailgating, or job-site use.
