SG 3/4/4.6/5KTL-M

Product catalog summary

Overview: The SG 3/4/4.6/5KTL-M is a grid-friendly, efficient solar inverter with dual MPPT and a wide MPP voltage range. It supports multiple communication methods, including RS485 and optional WiFi, and features a DC switch for safe maintenance.

Specifications: The inverter offers active power adjustment from 0 to 100% and reactive power control with a power factor adjustment range from 0.8 overexcited to 0.8 underexcited. It achieves a maximum efficiency of 97.4% to 97.6% and supports a wide DC input voltage range up to 550V.

Certifications: The device is TÜV, CE, AS4777, AS/NZS 3100, and VDE AR N 4105 certified, ensuring compliance with international standards.

Efficiency Curve: The efficiency curve indicates normalized output power efficiency ranging from 90% to 100% across different DC voltages (200V, 360V, 500V).

Input and Output Data: The inverter supports a maximum PV input power of 3000W to 4600W, with a nominal AC output power of 3000W to 4600W. It operates at a nominal AC voltage of 230Vac and a grid frequency of 50Hz/60Hz.

Mechanical and System Data: The inverter is transformerless, with an IP65 ingress protection rating, and supports natural cooling. It operates in ambient temperatures from -25°C to 60°C and at altitudes up to 4000m.

Protection Features: The inverter includes anti-islanding protection, DC reverse connection protection, AC short circuit protection, and leakage current protection. Overvoltage protection is provided by varistors.

Communication and Display: The inverter features a graphic LCD display and supports RS485 communication, with optional WiFi connectivity.
