INTELLIGENT INVERTER Bottom Freezer Refrigerators
Going up and down a set of large-sized stairs is a lot harder than it looks - just ask gray.

Reduce energy consumption by as much as 40%*1 with a Panasonic refrigerator featuring Intelligent Inverter
Intelligent Inverter is the revolutionary home appliance motor/compressor control system delivering convenient benefits, including reduced energy consumption, improved cooling efficiency, and flexible cleaning cycles, to a wide range of Panasonic products.
What is Intelligent Inverter?
Intelligent Inverter is a Japanese-developed technology that uses precise motor/compressor control to achieve improved efficiency and reduce energy consumption in home appliances. Conventional appliances only switch on and off - always at full power - and can't make minimal power adjustments, even for small operational changes.
With Panasonic's Intelligent Inverter technology, however, appliances operate at the optimal power setting, lowering your monthly electricity costs and providing a wide range of convenient benefits to improve your daily routine.
Increased Energy Savings
Panasonic's Intelligent Inverter makes precise adjustments to power settings for optimum performance. Just think how much you can save on your monthly electric bill if, for example, your air conditioner uses up to 50%*2 less electricity, or if your refrigerator - which is always on - uses up to 40%*1 less energy.
Quieter Operation
For non-Inverter appliances, especially those appliances that are always on such as refrigerators, noise can be a big hassle. With Intelligent Inverter, however, precise compressor rotation means quieter operation. Since your refrigerator needs less power to operate late at night, Intelligent Inverter can greatly reduce compressor noise and give you a better night of sleep.
Save Money with Intelligent Inverter
Forty percent less electricity consumption over 5 to 10 years can mean tremendous savings on your electric bill. Considering the cost of operating multiple appliances, don't you think it's time to try Intelligent Inverter and see the benefits for yourself?
