inverters , which convert direct current from solar panels to alternating current for the grid . These inverters are a crucial component in large-scale solar installations , helping to make renewable energy more efficient and cost-effective .
“ These , coupled with Battery Energy Storage Systems from Huawei , allow grids to regulate the quality of the grid as well in certain scenarios allow for peak shaving , allowing breathing space to over-loaded grids and smart energy cost-management ,” Sanjay explains . These systems help to balance the intermittent nature of renewable energy sources , storing excess energy during peak production times and releasing it when demand is high .
In the data centre space , Huawei has developed several innovative solutions to improve efficiency and reduce environmental impact . One such solution is the Power-POD , a modular system that integrates the complete electrical power infrastructure . “ This allows our customers , which include Hyper-scalers and Colocation players , to rapidly deploy MW-scale data centre facilities ,” says Sanjay .
The Power-POD incorporates highefficiency modular Uninterruptible Power Supply ( UPS ) systems with Lithium Iron Phosphate ( LiFePO4 ) batteries , known for their long lifespan and safety characteristics .
Cooling innovation a critical factor Cooling is perhaps the most critical challenge for high-density AI workloads . Traditional air-cooling systems can struggle to dissipate the heat generated

by densely packed , high-performance computing equipment efficiently .
To address this , Huawei has deployed new cooling architectures , including advanced liquid cooling solutions . “ Huawei has worked with hyperscalers to develop reference architectures to cater to the new requirements of liquid cooling in data centres ,” Sanjay explains . These solutions include innovations in hybrid cooling systems , heat exchangers and cooling distribution units ( CDUs ).
Liquid cooling , which involves circulating a liquid coolant directly over or very close to heat-generating components , is also more efficient and effective at heat removal than air cooling . This becomes crucial as rack densities increase , allowing data centres to pack more computing power into a smaller footprint while managing thermal loads effectively .
