Offgrid, solar powered fridge, with no battery bank
2 days ago
- Fridge0 is an offgrid, solar-powered fridge design that uses a modified chest freezer and thermal mass instead of a battery bank.
- It stores solar power as cold to avoid the high cost and environmental impact of battery banks, requiring only minutes of battery power for shutdown and computer control.
- Commercial offgrid fridges are expensive due to features like vacuum insulation and still may need batteries, but modern cheap solar panels make conventional fridges viable with a kilowatt setup.
- The concept was developed by Joey Hess and has been tested successfully for nearly a year, though specific locale and weather conditions are not fully detailed in the text.
- Requests for real-world data, schematics, and testing conditions (e.g., in hot climates like Austin, Texas) are mentioned as desired by users.
