At the Đồng Nai Hydropower Station in Vietnam, we’ve completed a 180kW solar installation featuring 1 × 𝗦𝗧𝗧-𝟭𝟭𝟬𝗞𝗧𝗟 and 1 × 𝗦𝗧𝗧-𝟱𝟬𝗞𝗧𝗟-𝗠 Sunways on-grid inverters. The system helps the plant achieve cleaner and more stable internal power supply through a practical water–solar complementary setup.

Project Highlights
- Stable Energy Supply: Solar compensates for reduced hydropower during the dry season; hydropower remains stable during rainy months.
- Internal Load Support: Sunways inverters provide efficient power to auxiliary systems within the plant.

Inverter Performance
STT-110KTL
- IP66 protection for demanding environments
- Up to 98.8% efficiency
- 10 MPPTs for flexible string design
STT-50KTL-M
- 4 MPPTs for precise tracking
- Low standby consumption for higher overall efficiency
- Flexible configuration for diverse system layouts

This project enhances the station’s energy self-sufficiency and demonstrates a practical example of Vietnam’s move toward diversified clean energy.
