SDT G4 Series 15-33kW | 3-Phase Multi-String

Residential PV Inverter SDT G4 Series 15-33kW | 3-Phase Multi-String

The SDT G4 Series smart PV inverter is engineered for residential and small commercial applications across 15-33kW power ranges. Featuring silicon carbide (SiC) semiconductor design for high power density and reduced losses, it achieves up to 98.7% max efficiency. With operational noise <45dB, zero derating at 300V voltage imbalance, and full-load output at 45°C ambient temperature, it delivers quiet, reliable performance.

160V low startup voltage and 21A max input current ensure compatibility with high-efficiency modules for maximized ROI. IP66 protection and Type II AC/DC surge protection guarantee resilience in harsh environments. Supports aluminum wiring to lower installation costs and dual RS485 channels for flexible "Four-Criteria" grid compliance. Advanced features include:

Single/multi-unit anti-reverse power flow

String current monitoring

Nighttime power supply
