The three checks
1/2 HP sump pump on its own, with nothing else plugged in, against the published ratings of the Goal Zero Yeti 1500.
| Check | Needs | Station has | Result |
|---|---|---|---|
| Running watts against continuous output | 925 W | 2,000 W | Passes |
| Starting watts against surge rating | 1,725 W | 3,600 W | Passes |
| A full day at 2 h a day | 1,850 Wh | 1,279 Wh usable | Fails |
How long it runs across models
The appliance class spans a range of models. Running time on a full charge at the low, typical and high figure in the data:
| Case | Running watts | Running time |
|---|---|---|
| Low end of the class | 800 W | 1.6 h |
| Typical | 925 W | 1.4 h |
| High end of the class | 1,050 W | 1.2 h |
Watts vary by model and age. Check the label on your own appliance and enter it for an exact answer.
Keeping up on solar
At 4 peak sun hours, counting 75% of the panel rating: 200 W of panels bring in about 600 Wh a day, 32% of the 1,850 Wh it uses at 2 h a day. 900 W of panels bring in about 2,700 Wh a day, more than the 1,850 Wh it uses at 2 h a day, so the station keeps up.
