Power cuts are unpredictable. Whether it be in rural or urban areas, most of us have experienced power cuts mostly because of load shedding. We use inverter battery backups to power some basic home appliances, but it could hardly power a large appliance such as a refrigerator, till now. Refrigerator manufacturers have introduced a Smart Inverter technology, which let you power your fridge even with a home inverter. This technology is pretty neat and can help you keep your food fresh even when you experience hours of long power cuts.
How does Smart Inverter technology work?
For years, traditional fridges have used single-speed compressors that either turns on or off. When a single-speed compressor circulates refrigerant through a fridge, it turns on and operates at its maximum speed (typically 3,600rpm). When the temperature inside the fridge reaches the desired mark, the compressor turns off.
Smart inverter fridges work in a complete different way than traditional fridges. These fridges are equipped with variable-speed compressors which can operate at speeds ranging from around a 1000rpm to 4300rpm. A variable-speed compressor is highly energy efficient and in events of power cuts, it runs on its lowest speed. This lets it power the fridge even through home inverter batteries. As these refrigerators draw very little power, they can run for hours on battery backup and keep food fresh. If you want to know about the advantages of using inverter technology in refrigerators, read through our feature on it.
A refrigerator run-time on inverter backup largely depends on the inverter’s capacity (VA – Volt Ampere) and the battery’s capacity (Ah – Ampere-hours). The VA denotes the capacity of voltage and current that an inverter can supply to appliances, while the Ah denotes the battery’s capacity in hours. In case of power cuts, most homes have at least one ceiling fan and two CFL bulbs running on inverter batteries. If we consider that the lowest power required to run a smart inverter fridge is 90W, the energy required to power all the appliances including the lights and fans would be approximately 185W.
We have made some rough calculations and put them down in the table below. This can guide you with knowing how long you can run a smart inverter technology fridge on inverter batteries. Note, these values are approximate and depend on the inverter, the batteries, usage patterns and from one refrigerator model to another.
| Inverter VA rating | Battery Ah | No. of hours on inverter battery |
| 600 | 60 | 2.1 |
| 900 | 60 | 4.8 |
| 1500 | 60 | 8.1 |
| 2000 | 60 | 10.8 |
Smart inverter fridges can really be a boon for those of us living in areas which experience frequent power cuts. Now we can finally stop worrying about food getting spoiled in our fridges. We have a wide range of Smart Inverter Refrigerators that you can now buy online. We also welcome you to come visit our stores as well to get a hands-on experience with our offerings.
