All across the world there is a big shift towards 48V DC systems and Scientific / Technology community is increasingly recommending it as a preferred system for the future DC evolution. Below are some of the reasons for this shift.  

• Reduction of losses: 

For a 100 Watts load, with a 12V system, the current is almost 10A, whereas with a 48V system, it will be 1/4th (about 2A).  The losses with the same cable for 12 V becomes 16 times as compared to 48V system. Alternatively, a thicker cable has to be used. 

 

• Future Scalability: 

1. Many quality appliances like BLDC Fans, Coolers, Mixers etc are designed for working with a nominal voltage of 48V DC.  
2. TV brands like Soni Brevia etc have already come up with TV sets with two input sockets (one with 230V AC and other with 48V DC, either can be used).  
3. Refrigerators, Dessert coolers and Air-conditioner are also being developed at 48V DC.  
4. No such possibilities exist for 12V/24V systems as of now. 

• Compatibility with existing wiring: 

Existing wiring for AC distribution system can be used for DC distribution on 48V DC (where applicable), which is not possible with 12V system. 

 

• More Standardized and Robust: 

48V System is a mature standard that is being used in telecom and automotive industries world over and all the learnings / innovations of these two sectors can be adapted in household sector. 

 

• Human Safety: 

Another misconception prevalent is that 48V is not as safe as 12V and 24V. Here it is pertinent to mention that 48V DC complies to Safe Extra Low Voltage (SELV) guidelines and same has been recommended by BIS for home system and MNRE has also included it in its guidelines. 

 

• Advanced Lithium Ion Technology: 

Over and above this, we would also bring to your kind notice that 48V systems made by Cygni are on advanced Lithium Ion battery technology where battery life is 8-10 years unlike all the available 12/24 systems with Lead Acid batteries which have a life of max 2-3 years. Once the battery goes after 2 years, the user is not going to purchase it and the system will go waste.  

Moreover, battery being the costliest component of the system, Lithion Ion based system has effective cost (Total Cost of Ownership) at around half or even less than corresponding Lead Acid based systems. 

We would like you to watch this link and see how these 48V systems provided by Cygni are changing lives of people:
