Tantangan,Philippines, February 3, 2026 — SinengElectric, in partnership with global solar developer ib vogt, supplied itsstring inverters to the 99 MWp Tantangan Solar Power Project in South Cotabato,Philippines, and successfully completed Factory Acceptance Test (FAT) inaccordance with the requirements of the Philippine Grid Code. Witnessed by theNational Grid Corporation of the Philippines (NGCP), the test marked a major step toward ensuring grid-ready operation.
For the project, Sineng Electric providedits 350 kW string inverters (SP-350K-HB1), paired with two types of integratedtransformer solutions—theITS-6400-MV and ITS-8960-MV. Together, these solutions are engineered todeliver high efficiency, robust grid support, and long-term reliability.
The NGCP-witnessed FAT verifiedthe stable performance of Sineng inverters across a wide range of gridconditions. The test evaluated key grid-support features, including low- andhigh-voltage ride-through (LVRT/HVRT), frequency response, voltage regulation,and overall system stability under grid disturbances.
At the core of theproject is Sineng’s 350kW string inverter, delivering up to 99% efficiency and equippedwith multiple MPPTs to ensure optimal energy harvest. Designed for the localhot, humid, and rain-intensive climate, the inverter features IP66 protectionand C5 anti-corrosion rating, enabling reliable operation under demandingenvironmental conditions.
In addition, theinverter delivers millisecond-level rapid reactive power response, allowingfast grid dispatch and dynamic voltage support—capabilities that areincreasingly essential for solar plants operating within modern, flexible powersystems.
Once fully operational, the TantanganSolar Power Project is expected to generate over 150,000 MWh of cleanelectricity annually, reducing CO₂ emissions by approximately 66,000 tonnes peryear. The facility will supply energy to power over 62,000 households,significantly reducing reliance on fossil fuels. The project also contributesto local employment and aligns with the Philippines’ broader energy transitionand decarbonization objectives.
By successfullycompleting FAT witnessed by NGCP, Sineng Electric reaffirms its ability todeliver grid-ready solar solutions, supporting the country’s transition toward aresilient, secure, and low-carbon energy system.
