The 25th International Power Industry and Renewable Sources of Energy Fair ENEX was held on March 8-9, 2023. As a well-known event in Europe, it has attracted the attention of 12 countries and over 200 international exhibitors, showcasing each company’s clean energy technology products. At the exhibition, TSUNESS Co., Ltd（TSUN) displayed its featured microinverters, easy solar kit as well as energy storage. TSUN’s participation in the event is a testament to its commitment to providing high-quality, reliable, and innovative solar energy products to customers in Poland and beyond.
- TITAN is high-profile for its high-efficiency and reliable-safety
The most attention-grabbing product at the exhibition is TITAN Microinverter. There are some reasons why this product stands out in the Polish market. On the one hand, this is due to the hot photovoltaic market in Poland. Poland has one of the fastest-growing markets for solar energy in the whole of Europe. Its PV market is expected to grow strongly during the current decade to reach 30 GW of installed capacity by the end of 2030, according to the Polish research institute Instytut Energetyki Odnawialnej (IEO).
One the other hand, TITAN has achieved a maximum power of 3KW for global single-phase micro-inverters, making it a perfect fit for the Polish market. the majority of mainstream PV modules in the Polish market are 182mm series. Taking the Hi-Mo 5m series as an example, under STC conditions, the power output of the component is 550W, the open-circuit voltage is 49.8V, and the short-circuit current is 13.98A. The maximum input current of TSOL-MP3000 is 18.5A, which is perfectly compatible with all 182mm and 210mm components.
Meanwhile, in comparison to traditional string inverters which adopt 1 or 2 MPPT designs, the TSOL-MP3000 has 6 DC inputs, with each input connecting to a single PV module. Each module has an independent MPPT that can be controlled separately, achieving module-level shutdown and operation functions. Compared to the solution of string inverters that connect to high-voltage grids in series, the output voltage of each route of the TSOL-MP3000 is lower than 60V, which is lower than the 80V voltage required by some countries. Therefore, the system has only around 60V DC voltage, completely solving the risk of fire caused by high-voltage DC arcing, resulting in higher safety performance. At the same time, the maximum power generation efficiency of each MPPT is achieved, thereby improving the overall power generation efficiency.
Taking the Polish residential market as an example, if 550W modules are selected, the total DC input power of six modules on the input side would be 3300W (550W*6). With an output power rating of 3000W for TSOL-MP3000, the over-configuration ratio of the photovoltaic modules would be 1.1, which would optimize module efficiency and maximize user benefits. At the same time, for household systems with a capacity of 8-10KW, using three TITAN micro-inverters is more cost-effective than the conventional one-in-one or two-in-one micro-inverters commonly used in the market.
- TITAN Microinverter Meets Stricter Demands in Poland’s PV Market
With the market growing rapidly, Poland has imposed stricter demands on PV inverter products than the European grid-connected standards for power generation equipment. According to the requirements set by the Polish Transmission and Distribution Association PTPiREE, PV inverters must fulfill the certification criteria of NC-RfG and EU Bulletin EU2016/631, in addition to meeting the standards issued by PTPiREE. The Polish power grid recognizes only those PV inverters that are certified by an accredited institution, which can then be sold in the local market.
The Goodnews is that TITAN Microinverter, TSUN’s featured product, has recently received certification from BUREAU VERITAS, a reputable certification body. BUREAU VERITAS conducted rigorous testing and evaluation to ensure that TITAN is safe, reliable, and performs as expected.
TSUN’s achievement of BUREAU VERITAS certification for the TITAN microinverter is a significant milestone for the company and a testament to the quality and performance of the product. With this certification, TSUN is allowed to continue to provide customers with more innovative and reliable solar energy solutions in Poland. The company’s participation in ENEX 2023 further demonstrates its commitment to the Polish solar market and its desire to be a leading player in the industry.
