Sungrow, the global leading PV inverter and energy storage system provider, has officially announced the launch of two groundbreaking products i.e. 1+X 2.0 Modular Inverter and PowerTitan 3.0 ESS.
According to certain reports, the stated pair of innovations arrives on the scene bearing an ability to maintain stable, high-efficiency operation in extreme conditions. More on that would reveal how 1+X 2.0 features a scalable block design ranging from 780kW to 9.375MW, as well as a front-in, rear-out cooling design to ensure stable full-load operation even at 52°C.
PowerTitan 3.0, on the other hand, is decked up with industry’s first large-scale fully liquid-cooled Silicon Carbide Power Conversion System (SiC PCS), capable of delivering exceptional efficiency (up to 99.3%) and consistent full-power output even at 55°C so to raise the overall energy storage system conversion efficiency to 92%.
Talk about the whole value proposition on a slightly deeper level, we begin from 1+X 2.0, which promises enhanced durability.
This translates to how the given solution is specifically made to thrive in the harshest of environments, such as high temperature and sandstorm area. It is able to do so on the back of high-performance components, efficient heat exchangers, and built-in safety margins across all critical parts.
Complementing that would be a unique dual-duct cooling system which separates hot and cold airflow to eliminate thermal interference, whereas on the other hand, a redundant thermal design really goes the distance to realize continuous full-load operation even at temperatures up to 52°C.
All in all, a IP66-rated fully sealed design, high-level protective materials, and self-cleaning air duct system empower 1+X 2.0 to maintain clean internal components and high reliability.
Next up, there is the prospect of leveraging a small module to make a big impact. Basically, 1+X 2.0 Modular Inverter makes it possible for users to achieve enhanced modularity with flexible scalability from 780kW up to 9.375MW through parallel units.
On top of that, the technology’s split modular design facilitates quick field replacement of critical components, reducing O&M time to just one hour per module. Equipped with an intelligent diagnostics function, it also delivers real-time fault detection that speeds up repairs and minimizes manual intervention.
Then, there is a facility to clock exquisite safety management. Here, 1+X 2.0 banks upon an Intelligent DC-Side Safety Management System to disconnect faulty circuits within 40 milliseconds to prevent such risks when an arc fault is detected, while simultaneously shutting down related combiner boxes.
Turning our attention towards PowerTitan 3.0, it delivers at your disposal full liquid-cooles and full-power operation. The stated facet effectively integrates a 1.72 MW PCS with 6.9 MWh batteries to deliver a 4-hour system where a single block reaches 6.9 MW/27.6 MWh. Not just that, with high-temperature-resistant SiC devices in the new PCS, the PCS is able to achieve up to 99.3% efficiency and sustain full-power operation without derating at 55°C.
Another detail we must expand upon relates to how PowerTitan 3.0 adopts a top-only exhaust design for both ESS and MVS, preventing hot and cold air from mixing. It further deploys Bionic Thermal Balance 2.0 to predict weather and operation plans, thus enabling flexible compressor and fan control, achieving ±1°C precision in temperature regulation, and cutting auxiliary power consumption by an extra 10%.
In case that wasn’t enough, it even gets to benefit from IP55 protection and C5 corrosion resistance to realize stable performance across the MEA’s diverse and harsh climates.
For projects demanding large capacity and cost-effectiveness, the PowerTitan 3.0 can even dip into Sungrow’s third-generation energy storage cells of 684Ah and 661Ah stacked cells. These stacked cells and optimized pack design can propel energy density to reach 467 kWh/㎡.
On top of that, a 1 GWh plant also needs only 7,270 ㎡—22% less than Sungrow’s previous generation.
“With abundant natural resources and strong energy transition policies, MEA has become a key growth market for the global solar and energy storage industries. Sungrow has enhanced technologies, including AC block design, high-level dust protection, and DC safety features to address local needs. Looking ahead, Sungrow remains committed to delivering not just competitive products, but superior quality, safety, lifecycle management, maximum ROI,” said Thompson Meng, Vice President, Sungrow.
