The three checks
Chest freezer on its own, with nothing else plugged in, against the published ratings of the EcoFlow DELTA Pro Ultra.
| Check | Needs | Station has | Result |
|---|---|---|---|
| Running watts against continuous output | 300 W | 7,200 W | Passes |
| Starting watts against surge rating | 750 W | 10,800 W | Passes |
| A full day at 24 h a day | 800 Wh | 5,222 Wh usable | Passes |
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 | Energy a day | Running time |
|---|---|---|
| Low end of the class | 0.55 kWh a day | 9.5 days |
| Typical | 0.8 kWh a day | 6.5 days |
| High end of the class | 1.26 kWh a day | 4.1 days |
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, 75% of the 800 Wh it uses at 24 h a day. 5,600 W of panels bring in about 16,800 Wh a day, more than the 800 Wh it uses at 24 h a day, so the station keeps up.
