At a Glance
This comparison targets buyers weighing a high-capacity whole-home backup unit against a lighter, more portable alternative. The Delta Pro Ultra X delivers 12,000W of running power and 6,144 Wh of battery capacity, making it capable of powering every one of the 53 devices tested in our compatibility check. The Pecron E3600LFP covers 47 of those same 53 devices on 3,600W and 3,072 Wh, which still handles the vast majority of household loads.
Solar input tells a similar story: the Ultra X accepts up to 10,000W, while the E3600LFP tops out at 2,400W, though it reaches a full charge faster at roughly 5.5 hours versus 7.3. Weight is the clearest tradeoff. At 79.4 lbs the Pecron is less than half the Ultra X's 187.4 lbs, a real factor for tailgating, job sites, or RV use.
The E3600LFP also includes UPS functionality with a 20 ms switchover, a feature the Ultra X lacks.
