Can the Goal Zero Yeti 1000X run Zoeller Model 53 3/10 HP sump pump, 115 V?

What watts were compared?

Station continuous output is 1,500 W. No motor-surge rating is applied. Appliance running draw is 1,116 W.

How was the runtime calculated?

997 Wh × 0.85 = 847 Wh usable, divided by 1,116 W average draw.

Where did the numbers come from?

Battery block: 997 Wh, NMC, 500 cycles to 80% at 1C, 31.68 lb. The ports section says 1,500 W and 3,500 W surge; a diagram label on the same page says 1,500 W and 3,000 W surge. The surge is omitted because the page disagrees with itself. Continuous 1,500 W is consistent. Zoeller lists the Model 53 at 3/10 HP, 115 V or 230 V, and 4.8–9.7 A. The 115 V automatic model in Zoeller's 50-series technical table is 9.7 A. Running watts used here are 9.7 × 115 = 1,115.5 W. Startup amps are not published. How often the float runs is site-specific, so no duty cycle is stored.
