At a Glance
This comparison targets buyers weighing a whole-home backup powerhouse against a lightweight portable unit. The Delta Pro Ultra X delivers 12,000W of running power and 6,144 Wh of capacity, enough to handle every one of the 53 devices we tested.
The Explorer 1000 v2 covers 33 of those same 53 devices, relying on 1,500W of output and 1,070 Wh of stored energy. That gap in device compatibility (100% vs. roughly 62%) reflects a fundamental difference in intended use.
Where the Delta Pro Ultra X supports 10,000W solar input and expansion batteries, the Explorer 1000 v2 counters with a 20ms UPS transfer, 4,000 cycle longevity, and a 23.8 lb frame you can actually carry with one hand. The tradeoff is straightforward: total coverage and capacity versus grab-and-go portability and a longer cycle life.
