During SNEC 2025, held from June 11 to 13 in China, TBEA SUNOASIS presented to the public a series of new products aimed at the utility-scale and energy storage segment, which are expected to reach the international market in the coming months. The new products reinforce the company's strategy of offering solutions with greater energy density, modularity and operational efficiency.
Among the main highlights of the Manufacturer is the new modular solution for central inverters. TBEA SUNOASIS presented 800 kW equipment, which can be configured in blocks of 1,6 MW, 3,2 MW and up to 4,8 MW or 9,6 MW, using 20 or 40 foot containers.
According to Daniel Lyrio, Sales Manager at TBEA SUNOASIS in Brazil, this evolution represents a paradigm shift in relation to traditional models. “We are seeing a migration from the 1,5 MW configuration to 800 kW central modules, which already come integrated with a transformer and RMU in more compact versions. This trend, which is still under development in China, will soon also be available in Brazil and other international markets,” he highlighted.
PCS solutions for BESS with plug-and-play concept
In the storage segment, TBEA SUNOASIS presented a PCS (Power Conversion System) solution specially developed for large-scale applications. The system has 24 215 kW PCS units, integrated in a 20-foot container, forming a 5 MW power set.
“It is a fully plug-and-play solution, with low voltage panel, protection system, PSC, RMU and TBEA’s own transformer (which makes the solution unique), all ready for immediate operation. This configuration is ideal for projects participating in auctions in Brazil, with the possibility of replication in packages of up to GW”, explained Lyrio.
Energy density and systems integration
Another difference presented was the integration of batteries and PCS in the same container, increasing the energy density per square meter of installation. According to the manager, depending on the generation of cells used, the capacity can vary between 5 MWh and 6,25 MWh per unit. “If the project uses second-generation cells, we can reach 6,25 MWh per container, increasing efficiency and reducing the need for physical space.”
In this model, the PCS manages a single battery cluster, delivering 400 kW of power per unit with an alternating current output of 690 V. The only external step required is the coupling of a transformer.
Trend in higher power string inverters
In addition to central and storage solutions, TBEA SUNOASIS presented the new 450 kW string inverter, expanding the line that had already been evolving with 150 kW, 250 kW, 330 kW and 360 kW models.
“The launch of the 450 kW inverter follows the trend of more powerful and efficient equipment, allowing better use of the electrical infrastructure of projects. This model will also be available in Brazil soon”, concluded the engineer from company.
