SDT G3 Series 27-50kW | 3-Phase Multi-String

Residential PV Inverter SDT G3 Series 27-50kW | 3-Phase Multi-String

The SDT G3 Series smart PV inverter is engineered for residential and small commercial rooftop solar systems, covering power ranges from 8-50kW. Featuring a unified aesthetic with magnesium-aluminum alloy stretch-forming technology, it delivers both industrial elegance and durability. Ultra-quiet operation (as low as 29dB) ensures minimal noise disruption. Advanced inverter control achieves up to 98.8% max efficiency, 160V ultra-low startup voltage, and 22A max input current – fully compatible with high-efficiency modules for increased energy yield.

With IP66 protection for harsh environments, optional DC arc-fault detection (AFCI), rapid shutdown (RSD), and Type II surge protection enhance system safety and lifespan. Supports aluminum wiring to reduce installation costs, while integrated string monitoring, IV curve scanning, and nighttime power supply enable intelligent energy management.

✅ Key Advantages

1.5x DC overmatching | 1.1x AC continuous overload

IP66 dust/water resistance

DC arc-fault protection support

AC/DC Type II lightning surge protection

⚡ AFCI 3.0 | Advanced Arc Detection Technology

AFCI 3.0 employs AI algorithms to process massive datasets, creating proprietary arc signature libraries through continuous deep learning (A5 architecture). This dynamically adapts to unknown frequency spectra and noise interference. Key innovations include:

30A max compatibility for high-power modules

200m detection range

Solid control chip: Achieves shutdown within <0.5s (vs. industry standard 2.5s)

Zero false positives/negatives: 100% detection accuracy

AFCI 3.0: Faster (<0.5s) | Smarter | Safer

Precision data capture • Instant shutdown response
