DN3-Series(30-50KTL)

Product Introduction  

The DN3 Series (30 – 50KTL) Three-Phase Grid-Tied Inverter is a core component of solar power systems, engineered for efficient and stable power conversion. It works seamlessly with PV modules over 600W, unlocking their full power generation potential. With a 150% DC input overload capability, the inverter maintains stable performance even under complex and fluctuating DC input conditions. It also supports 110% AC overload, providing extra power during demand peaks. Remote firmware upgrades ensure that the inverter stays up to date with the latest features and performance enhancements. Selected models offer optional AFCI (Arc Fault Circuit Interrupter) and intelligent PID recovery, further enhancing system safety and energy yield. With a startup voltage as low as 200V, it can begin power generation even under weak sunlight. Additionally, both DC and AC sides are equipped with Type II SPDs (Surge Protection Devices), protecting the system from electrical surges and ensuring safe operation.
