Berlin, Sept. 11, 2025 — At IFA 2025, Midea RAC Division unveiled its most emblematic sustainable innovations, highlighting the company’s long-term commitment to environmental responsibility in the global HVAC industry. Under its philosophy “GREEN VISION, BLUE FUTURE,” Midea introduced next-generation solutions designed to accelerate the low-carbon transition while ensuring user comfort and energy efficiency.
Pioneering R290 Refrigerant Technology
Central to Midea’s presentation were its R290 refrigerant-based solutions, which the company has promoted for over 15 years. Since establishing the world’s first UN-backed R290 production line in 2010, Midea has expanded to 12 advanced production lines with an annual capacity of 6.4 million units, enabling measurable global reductions in carbon emissions.
Backed by 10,000+ R&D experts and 42 pilot laboratories, Midea offers a full range of R290 products. Among them is the H-Pack hybrid heat pump, designed by its European R&D team. Using R290, the compact, outdoor-unit-free solution integrates seamlessly with gas boilers, offering efficiency and reliable heating even in extreme cold conditions.
Raynor: Nordic Strength Meets Design Excellence
Midea also highlighted Raynor, its flagship low-temperature air source heat pump, boasting an A+++ energy rating and a SCOP of 5.1. Tested in extreme climates, Raynor can operate at -40°C, maintain 5.0 kW heating at -25°C, and deliver peak power up to 8.0 kW.
Engineered with anti-freeze and anti-corrosion technologies, including Prime Guard Hyper Grapfins, a heated chassis, and Flash Defrost bearings, Raynor ensures reliability in Nordic coastal conditions. Recognized with the iF Design Award and Red Dot Design Award, Raynor also earned the Gold Award for Excellent Heating Technology Innovation at IFA 2025, presented by IFA CEO Leif Lindner to Midea executives Vincent Chou and Ralph Kobsik.
Solstice: AI-Powered Comfort with ECOMASTER
Midea’s Solstice AI-powered air conditioner represents the next step in intelligent comfort. Featuring a 180° rotating wind deflector for balanced airflow, Solstice leverages Midea’s latest AI engine, ECOMASTER, trained on billions of data points.
ECOMASTER predicts environmental changes, optimizing energy use and maintaining comfort within ±0.3°C, while cutting energy consumption by 30%. Midea also announced a collaboration with Microsoft to integrate natural voice control powered by Microsoft Azure, supporting 145 languages for seamless global usability.
Driving the Low-Carbon Transition
Midea’s showcase at IFA 2025 reinforced its role as a pioneer in sustainable HVAC technologies, combining engineering excellence, AI-driven solutions, and eco-friendly design. From refrigerants that reduce carbon footprints to smart systems that enhance comfort, Midea continues to deliver practical, sustainable, and globally scalable innovations for a greener future.
Sigenergy, a leading innovator in energy technology, unveiled its full portfolio of residential and commercial & industrial (C&I) solutions at Intersolar South America. From high-performance inverters and scalable storage to integrated residential systems, the company’s latest offerings aim to accelerate Latin America’s transition toward energy resilience and independence.
Driving Latin America’s Energy Transition
Latin America faces rising energy demand and growing calls for sustainable solutions. Sigenergy’s expanded product range responds directly to these challenges, delivering scalable systems that enhance grid reliability while reducing costs. By showcasing its technology at Intersolar, Sigenergy is reinforcing its role as a partner in the region’s clean energy transformation.
Commercial & Industrial Solutions
Sigenergy introduced its C&I inverter portfolio, covering PV, HYA, and HYB models ranging from 50 kW to 125 kW. The HYB model supports seamless on/off-grid switching with capacities of up to 110 kW, and up to three units can be paralleled without additional gateways.
Complementing these inverters is the SigenStack energy storage system, a high-density, DC-coupled modular solution. Each 12 kWh module scales up to 250 kWh per inverter, delivering optimized round-trip efficiency and simplified deployment for businesses aiming to maximize energy utilization and resilience.
From SigenStor to Microinverters
At the residential level, Sigenergy highlighted SigenStor, the world’s first 5-in-1 energy system. Already a global success, it integrates a PV inverter, battery, EV charger, EMS, and PCS into a compact modular design. Systems can scale beyond 54 kWh and even support C&I projects when connected in parallel.
The company also introduced its second-generation hybrid inverter, featuring a slim, fanless design with industry-leading 99% efficiency on three-phase models. Operating at noise levels below 25 dB, it delivers robust off-grid performance with an IP66 rating and wide temperature tolerance.
For emerging markets like balcony PV, Sigenergy launched SigenMicro, a microinverter with patented DAB topology, built-in EMS, and IP67 protection. With WLAN Mesh architecture boosting coverage by 1600% and five-minute commissioning, it redefines safety, simplicity, and scalability.
Enabling Smarter, Greener Futures
By offering an integrated and modular product ecosystem, Sigenergy positions itself as a driver of energy innovation in Latin America. Its solutions are tailored to empower both homeowners and businesses, bridging the gap between decentralized renewable energy adoption and grid resilience.
