Despite the stabilizing trend in the European and American micro-inverter markets, they remain the primary global largest markets.
Industry forecasts project an 80% compounded annual growth rate for global micro-inverters between 2021 and 2025. Over the forthcoming seven years, Europe is anticipated to generate a market shortfall of 130 million units in micro-inverters , expanding this demand to exceed 400 million units worldwide.
Considering the current market average price of micro-inverters ranging from 2000 to 3000 yuan, an additional trillion-dollar market segment appears imminent. In this era, Chinese micro-inverter firms are swiftly penetrating international markets, leveraging innovation and transformative strategies.
"Anticipating order projections, we foresee shipping between 500,000 to 1 million micro-inverters next year," stated Zhao Peng, Chairman of TENTEK New Energy. He emphasized that while the micro-inverter market continues on a rapid growth trajectory, the core competition lies in product safety, stability, and practicality.
Peng further elucidated that due to climatic unpredictability, outdoor power grids demand micro-inverter products tailored to local grid compatibility, aligning with resident consumption patterns and power usage.
As a burgeoning inverter enterprise, TENTEK New Energy boasts an extensive network of distributors across numerous countries and regions, establishing sales and service channels spanning Europe, the United States, Japan, Southeast Asia, among others.
Forging Micro-inverters with Energy Storage Capabilities
The volatility of outdoor scenarios and the diverse voltage, frequency, and load variations across power grids contribute to fluctuating power requirements. Micro-inverters endowed with energy storage capabilities facilitate modular energy storage, allowing seamless transitions to off-grid power supply during grid anomalies by utilizing stored energy to ensure uninterrupted power supply. Consequently, micro-inverters equipped with energy storage capabilities emerge as indispensable commodities in the market.
Established in 2022 as one of TENTEK Group's holdings, TENTEK New Energy swiftly innovates despite its recent inception. Analyzing micro-inverter usage scenarios, they outlined product development focused on on/off-grid functionalities, energy storage, AC coupling, primarily targeting ordinary household markets in the application domain.
The initial generation of TENTEK New Energy's micro-inverters not only integrates seamlessly into standard grid-connected systems but also extends functionality for portable power sources, resolving grid-connected sales challenges for portable systems. Moreover, in household energy storage applications, these micro-inverters facilitate zero-feedback operations, UPS functionality, off-grid operation, effectively addressing grid instability concerns and enabling surplus electricity storage for self-consumption of solar energy. With an IP67 protection rating and a 25-year design life, they prove ideal as off-grid power systems for RVs, yachts, and similar challenging environments.
Zhao Peng reiterated in interviews with Tide Electric Think Tank the critical importance of seasoned professionals in the micro-inverter industry to the company.
The core R&D team at TENTEK New Energy boasts over 15 years of inverter expertise, while manufacturing floor managers possess over a decade of production management experience. Tailoring exclusive micro-inverters for specific scenarios such as hospitals, schools, and gas stations, they conduct extensive testing and data collection, employing patented global-first-tier topology structures, based on different climates and unique environments in overseas regions.
Focused on Household On/Off-Grid Micro-inverters
Micro-inverters with off-grid capabilities demand elevated technological thresholds.
At the "2023 Global Inverter Trends Summit and Annual Awards Ceremony", TENTEK New Energy's Sales Director, Li Wenke, highlighted that the next-generation representative inverters in portable power sources are undoubtedly on/off-grid micro-inverters .
Chairman Zhao Peng underscored the off-grid advantages of TENTEK New Energy's micro-inverter products in conversations with Tide Electric Think Tank.
TENTEK New Energy's micro-inverter products autonomously switch between grid-connected and off-grid modes based on power grid and load conditions. They enable self-consumption and surplus electricity feeding into the grid during regular grid operation. During grid outages, they seamlessly transition to off-grid mode, establishing an independent micro-grid with batteries and loads, ensuring uninterrupted load operation.
In contrast to Enphase's utilization of three-stage energy conversion for AC coupling to enable energy storage, TENTEK New Energy employs two-stage energy conversion for DC coupling to facilitate photovoltaic energy storage, thereby enhancing efficiency and cost-effectiveness.
Simultaneously addressing the demand for household-level on/off-grid energy storage micro-inverters, TENTEK New Energy provides intelligent monitoring systems and operation platforms, offering modern households a comprehensive smart solar storage solution.
The second-generation micro-inverters from TENTEK New Energy boast compact designs, efficient heat dissipation, high protection levels, on/off-grid switching functions, and an integrated MPPT controller. These micro-inverters can be directly integrated into portable power sources and home energy storage units, facilitating bidirectional inversion. They are suitable for regions with peak-valley electricity pricing, assisting ordinary households in managing low-power peak-shaving demands and saving on electricity expenses.
Currently, TENTEK New Energy's Tribune series EMS controller integrates (MPPT + AC) battery chargers and energy management functions. When combined with TENTEK New Energy's Tiger series micro-inverters, they establish a household solar micro-storage system with a maximum output power of up to 4KW.
Utilizing a special circuit design akin to a photovoltaic simulator, the EMS controller can pair with various brand inverters, ensuring controllable power in scenarios with minimal household loads, enabling complete self-consumption of solar power and cost savings. This controller is set to enter the market this month.
In the future, the company plans to develop 3-4KW high-power micro-inverters for export to the European market.
