Our fridge has voltage and short circuit protection, temperature control, and interior lighting. ?[Energy Efficient and Cost Effective]: Cowin's solar refrigerator will save consumers money on their electricity bills in two ways. First, DC power from the solar panel is free since it is not coming from the grid, and second, our fridge is energy efficient so when AC power needs to be used from the grid, minimal energy is used to power the fridge. ?[Battery Charging Capability]: Our appliances are compatible with 12V / (80-200)AH batteries.
