From February 7th to 8th, 2024, the 26th Poland International Renewable Energy Exhibition (ENEX) was grandly held at the Kielce International Exhibition Center in Poland. Austa, a brand under Osda, showcased N-type TOPCon high-efficiency photovoltaic modules; integrated solutions for household photovoltaic storage, "balcony economy" micro-inverter system integrated solutions, and integrated solutions for high-voltage energy storage systems, dazzlingly appearing in Poland.

ENEX is the most influential renewable energy exhibition in Poland, where more than 300 upstream and downstream new energy companies from around the world gather to showcase the latest technological achievements and products, and jointly explore the future development trends of the industry. Currently, over 37% of Poland's installed capacity in the energy structure is from renewable sources, with a majority being photovoltaic. Supported by net metering plans and government initiatives, Poland's residential rooftop market has been thriving. In 2022, Poland was one of the countries in Europe with the largest increase in photovoltaic installed capacity.

AU Series

N-type TOPCon Modules

At this Poland exhibition, Austa exhibited three AU series N-type TOPCon modules. Among them, the 430W all-black double-glass module is suitable for the current demand in Poland and even Europe for household rooftop photovoltaic markets. The all-black appearance design conforms to minimalist aesthetics, allowing the module to seamlessly integrate into residential rooftops. The 700W double-glass module is suitable for large ground-based power stations, with the module using 210mm large-sized silicon wafers, achieving a maximum power of 700W. Meanwhile, the double-glass structure provides the module with stronger durability and wind pressure resistance, making it more adaptable to various climatic conditions.

Compared to traditional P-type modules, N-type TOPCon double-glass modules offer higher bidirectional benefits, better high-temperature electricity generation performance, excellent low-light performance, and lower per watt sea freight and per kWh costs. As of February 2024, the highest conversion efficiency of AU series modules in mass production can reach 23.02%. Austa's N-type TOPCon modules will provide strong guarantees for customers' station investments to achieve greater returns and excess profits in the future.

Integrated Solutions for High-Voltage Energy Storage Systems in All Scenarios

Micro-inverter System

High and Low Voltage Energy Storage Systems

In the first year of 2024, Austa's Energy Storage Division, according to market demand, empowered products with a new technological platform and built a green life with zero-carbon technology. This time, Austa's Energy Storage Division launched a new ⌈Integrated Solution for High-Voltage Energy Storage Systems in All Scenarios⌋. The new AU4-15KETH high-voltage energy storage inverter, using second-generation technology platform, is small and lightweight (520*400*230mm, 28kg). Equipped with a 32-bit floating-point microcontroller, the control algorithm improves closed-loop performance, supports 120% three-phase unbalanced output, adapts to 18A large modules, and can parallel up to 9 units. With a maximum conversion efficiency of 98.4%, 160V ultra-low start-up voltage, and built-in multiple protection modules. It supports multiple communication methods, IP66 protection level, and anti-backflow protection. Achieving intelligent diagnosis, remote monitoring, and maintenance management.

The self-developed low-voltage energy storage lithium battery BMS system by Austa's Energy Storage Division adds big data elements to the traditional BMS system, providing data collection and analysis through the cloud platform, optimizing BMS control strategies, improving battery performance, and enhancing battery safety. Subsequently, Austa will also customize personalized software services for customers based on this cloud platform, truly realizing the intelligent application of energy storage.
