Campervan Fridge Picker (12V vs 230V)
Compare 12V compressor vs 230V through inverter for your van. See daily Wh, battery impact, and solar coverage to choose smart.
Is a 12 V compressor always better than 230 V via inverter?
Not always, but often for off-grid use. 230 V adds inverter overhead and tends to use more Wh/day. If you mostly camp on hook-ups and already have an inverter, 230 V can be acceptable.
How big should my battery be for either option?
Start from your **Wh/day** result, choose a comfortable **days of autonomy**, then convert to Ah at 12 V (Wh ÷ 12). Leave headroom for other loads and poor-sun days.
Will solar fully cover my fridge?
Enter your solar watts to see a **coverage %** estimate. In summer with decent roof area, a 12 V compressor is often largely covered; 230 V usually needs more solar or hook-ups.
Can I switch to 230 V later if I add an inverter?
Yes, but plan wiring, ventilation and space now. Also check that your inverter surge and continuous ratings comfortably exceed fridge start-up and run loads.
Why does usage pattern change the result?
More days in colder seasons and higher ambient temperatures affect duty cycle and inverter efficiency. The tool adjusts typical Wh/L to reflect that.
