Sungrow 125kW grid-tie inverter – Inverter Sungrow SG125CX-P2 is officially distributed by XBSolar Joint Stock Company. It is a string inverter with 12 independent MPPTs, achieving a maximum efficiency of up to 98.5%. It is compatible with various types of solar panels (mono, poly, bifacial, and thin-film technology). With a range of superior features, users can experience ease of operation and maintenance through various communication and monitoring options provided by the Isolarcloud web platform or application.
- The solid aluminum alloy casing design ensures durability while maintaining a lightweight construction, weighing only 87 kg, making installation tasks easier. All Sungrow solar inverter components are designed with separate boards for easy replacement and maintenance over time during operation.
- The integrated software allows users to monitor intelligent current flow on each string, perform online IV curve scans and diagnostics, and accurately locate abnormal PV positions. With advanced system diagnostics, remote data upgrades facilitate convenient operations and maintenance (O&M) tasks.
- The integrated Recovery PID function addresses Potential-Induced Degradation (PID), which can significantly impact the performance of solar systems. PID is a complex process influenced by various factors, resulting in decreased power output of both individual PV modules and entire strings over time. System power output can decrease by up to 90% due to PID. The Recovery PID function can repair degraded PV modules and increase productivity by up to 10%.
- Sungrow 125kW grid-tie inverter is designed to be compatible with both copper and aluminum AC cables, offering flexibility in design and optimizing installation costs. It can connect two DC cables in 1, replacing the traditional method of connecting DC cables, thereby saving DC electrical cable costs.
- With an intrusion protection rating of IP66 for the inverter, IP68 for the intelligent cooling fan, and corrosion protection rated at C5, the Sungrow 125kW grid-tie inverter demonstrates excellent resistance to environmental factors. This makes it suitable for various installation scenarios and harsh environments, including coastal areas in Vietnam.
- The P&Q function at night, LVRT (Low Voltage Ride Through), HVRT (High Voltage Ride Through), active and reactive power control, and power ramp rate control.
- Active shading optimization mode.
