The inverter’s IP66 and C5 anti-corrosion protection enables it to perform reliably even in challenging environments.

These inverters also support active and reactive power control, featuring the ‘Q at Night’ function for grid support and LVRT and HVRT capabilities for grid stability. Additional features like PID recovery maintain system efficiency, while the IP66 and C5 anti-corrosion protection ensure durability. These inverters are compatible with bifacial modules and are certified for the EU market. The SN125PT string inverter, designed for the 1100 Vdc commercial and industrial segment, includes 5 MPPTs and advanced features such as night-time PID recovery and a built-in arc-fault circuit interrupter for improved safety. Its smart I/V curve diagnosis offers real-time PV system monitoring.
