Rainy-season operation usually stays within normal upright freezer watt bands, but runtime can shift with humidity and room airflow.
For full system planning, use the WattSizing Calculator.
Quick Answer
Typical running draw is 100 to 300 watts, startup 700 to 1,800 watts, and many homes see mid-range daily kWh relative to summer and winter.
Rainy-Season Notes
Lower temperature can help, while moisture and blocked vents can push runtime up. Keep condenser paths clean and dry.
Typical Ranges
| Upright Size | Running Watts | Starting Watts | Typical Rainy-Season kWh/day |
|---|---|---|---|
| 8-10 cu ft | 90 - 150 W | 600 - 1,000 W | 1.4 - 2.5 |
| 11-14 cu ft | 120 - 200 W | 800 - 1,300 W | 1.9 - 3.2 |
| 15+ cu ft | 170 - 320 W | 1,100 - 1,900 W | 2.5 - 4.1 |
Practical Example
A mid-size unit averaging 150 W:
- kWh/day = (150 x 24) / 1000 = 3.6

FAQs
Does humidity increase watt draw directly?
Mostly it affects runtime conditions, not the nameplate running watts.
Is surge sizing seasonal?
No, surge planning remains essential in every season.
Should I track rainy-week usage separately?
Yes, especially for backup and off-grid sizing accuracy.
