Sungrow unveils 1 + X 2.0 modular inverter
Rheem ® expands commercial product offering
Rheem ®, a global manufacturer of HVACR and water heating products, announced the expansion of its commercial product offering with a higher efficiency extension to the well-received Renaissance™ Line. The packaged rooftop G / E and A / C lineup now includes 3-5-ton models with two stages of cooling and are purpose-built for commercial heating and cooling, delivering exceptional efficiency and value. Engineered for seamless replacements, Rheem Renaissance RACCYC and RGECYC units boast industry-standard footprints, common piping and electrical connections, field-convertible airflow, and minimized weight for unmatched ease of installation. Key features of the Renaissance 3-5 ton two-stage line extension include: PlusOne HumidiDry: HumidiDry hot gas reheat incorporates a variable
frequency drive( VFD) that operates at a lower speed on the first-stage cooling, saving energy, enhancing performance, and increasing occupant comfort. PlusOne ServiceSmart™: Built-in features designed with feedback from HVAC field professionals to improve serviceability and provide easy access to unit components. Qwik-change flex-fit rack capable of accommodating up to fourinch MERV 8 or MERV 13 filters, ensuring improved indoor air quality. Qwik-Slide Blower: This feature allows for extremely easy access and removal of the blower assembly for servicing internal components. Qwik-Clean Drain Pan: A composite material pan that slides out completely allows for effortless cleaning and includes a standard overflow sensor. PlusOne Velocifin™: A patented, complete redesign of the heat exchanger tubing that increases heat transfer through to deliver better efficiencies. Full MicroChannel Coils: Maximizes reliability while reducing overall refrigerant weight and improving serviceability, offering cost-saving advantages.
Sungrow, the inverter and energy storage system provider, unveiled its groundbreaking 1 + X 2.0 Modular Inverter for utility-scale applications during the Global Renewable Energy Summit 2025, held April 7-9. The 1 + X 2.0 Modular Inverter features a more scalable block design( 800kW to 9.6MW), stable operation without derating at temperatures up to 52 degrees Celsius, AI-driven fault detection, and pioneering gridforming capabilities, meeting the high demands for superior performance, maximum availability, and enhanced reliability of the inverter. The 1 + X 2.0 Modular Inverter provides increased modularity compared to the previous version. With each unit having a power rating of 800kW, the inverter provides flexible scalability from 800kW to 9.6MW( single unit to 12 units in parallel). This results in great flexibility which covers various scenarios.
The product’ s split modular design isolates critical components( IGBTs, capacitors) in the upper inverter module for quick field replacement. Operation and Maintenance( O & M) time is slashed to one hour per module swap— the easy O & M enables field engineers to perform quick replacements. With the AI-powered diagnostics function, the 1 + X Modular Inverter provides real-time fault identification, eliminating manual troubleshooting and delays, accelerating repairs, and minimizing reliance on manpower. Engineered to be robust in harsh conditions such as scorching heat in the Middle East, the 1 + X 2.0 Modular Inverter integrates high-power-density semiconductors, a high-efficiency heat exchanger as well as a dualcycle thermal management system to ensure optimized heat dissipation, maintaining stable operation without derating when the temperature reaches up to 52 degrees Celsius.
Vertiv launches new OCP-compliant power shelf
Vertiv last week announced the launch of PowerDirect Rack, a 1U high-density 50V DC power system shelf. The company said the new shelf is designed to bring resilience to demanding AI and highperformance computing( HPC) environments. The modular system scales up to 132kW per rack by integrating multiple power shelves, enabling expansion while minimising space requirements. Built for Open Compute Project( OCP) ORv3 High Power Rack( HPR) environments, the hot swappable shelf supports both AC and HVDC input. It is available globally. The company recently announced an upgrade of its thermal management product portfolio with
the introduction of the Vertiv Liebert EFC free cooling unit with low-GWP( Global Warming Potential) refrigerant. The company said the solution is designed to meet stringent environmental standards – including EU F-Gas regulation 2024 / 573, and IPCC AR4 – for data center applications and is now available across Europe, the Middle East, and Africa( EMEA) with capacities ranging from 150 to 450kW. Combining the capabilities of indirect air-toair heat exchange and evaporative cooling principles in a single unit, the polymer heat exchanger and the new low-GWP inverterdriven compressor technology significantly enhance annual efficiency by up to 19 percent compared to previous technologies, allowing a pPUE( partial Power Usage Effectiveness) as low as 1.05.
