Industrial-grade 3-phase inverter optimized for heavy machinery and off-grid manufacturing sites across Japan.
Engineered for bidirectional energy management and battery storage microgrids in Japan's public and industrial infrastructure.
Equipped with digital DSP control, this 3-phase hybrid inverter provides high-precision pure sine wave output for sensitive industrial electronics.
Advanced Power Conversion System (PCS) tailored for utility-level battery integration, supporting high-voltage battery banks.
Japan is rapidly shifting from the traditional Feed-in Tariff (FIT) scheme to the Feed-in Premium (FIP) market-integrated model. This transformation demands that industrial solar installations and microgrids operate with intelligent, grid-responsive power systems. Power plants must dynamically balance load profiles, actively participate in peak-shaving, and prevent grid congestion under utility areas like TEPCO, KEPCO, and Chubu Electric.
To maintain profitability under the FIP scheme, developers require robust power conversion systems (PCS) capable of bidirectional control, immediate battery dispatch, and rapid response to grid frequency fluctuations. Our specialized systems are designed to bridge this technical gap, ensuring Japanese commercial energy assets yield optimal ROI while strictly complying with local electricity business laws.
Compliant with METI grid connection guidelines, featuring active anti-islanding detection and high-speed FRT (Fault Ride-Through).
Engineered cabinet frames and structural durability parameters adapted for high seismic and typhoon zones in Japan.
