SDT G3 Series 8-15kW | 3-Phase Dual-String

Residential PV Inverter SDT G3 Series 8-15kW | 3-Phase Dual-String

The SDT G3 Series smart PV inverter delivers versatile performance for residential and small commercial rooftop systems across 8-50kW power ranges. Its unified design features magnesium-aluminum alloy stretch-forming technology for robust aesthetics. With ultra-quiet operation (as low as 29dB) and advanced control achieving 98.8% max efficiency, it ensures optimal energy harvest through 160V ultra-low startup voltage and 22A max input current – compatible with all high-efficiency modules.

IP66 protection withstands harsh environments, while optional DC arc-fault protection (AFCI), rapid shutdown (RSD), and Type II surge protection enhance safety and system longevity. Supports aluminum wiring for cost savings and offers smart features including:

String current monitoring

IV curve scanning

Nighttime power supply

✅ 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 Hunting Technology

AFCI 3.0 leverages AI algorithms to process mass data, building proprietary arc signatures through A5 deep learning architecture. Continuously evolving detection models improve noise immunity while supporting:

30A high-current compatibility (matches large-format modules)

200m detection range

Dedicated control chip: Shutdown in <0.5s (vs. 2.5s industry standard)

100% accuracy: Zero false positives/negatives

AFCI 3.0: Faster (<0.5s) | More Precise | Safer

Comprehensive arc capture • Instant intelligent shutdown
