Capacity
Delta Pro: +1,552 Wh (+75.8%).
This comparison targets buyers weighing a midweight portable station against a high-capacity home backup unit. The Delta Pro delivers 3,600W of running power and 3,600 Wh of capacity, nearly doubling the AC200L's 2,048 Wh reserve and exceeding its 2,400W output by 50%.
Surge capacity tells a similar story: 7,200W versus 3,600W, giving the Delta Pro the headroom to start demanding motors and compressors. In device compatibility testing across 53 appliances, the Delta Pro powered 47 while the AC200L handled 43, earning scores of 95 and 83.5 respectively.
Both use LFP chemistry and support expansion batteries, so longevity and scalability are comparable. The tradeoff is weight and recharge time: the AC200L comes in at 62.4 lbs with a 7.3-hour solar fill, while the Delta Pro weighs 99.2 lbs and needs up to 12.9 hours from its 1,600W solar input.
