Description
The Deye SUN-3K-G is a compact, highly efficient 3 kW single-phase grid-tied string inverter designed for small residential rooftop solar installations.Engineered for direct PV-to-grid power conversion without battery storage, it features a low startup voltage of 80V to extend daily power generation hours into early morning and late afternoon periods.Equipped with an integrated DC switch, zero-export application support, and natural convection cooling, it provides reliable, silent, and low-maintenance operation.
Key Features & Benefits
Low Startup Voltage (80V):Allows the inverter to turn on early and operate across a wide MPPT range (70V–500V) for maximum daily yield.
High Conversion Efficiency:Delivers up to 97.5% maximum efficiency (97.3% European efficiency) to minimize energy conversion losses.
Zero Export & VSG Application: Integrates power limiting control when paired with an external meter or CT to meet strict zero-feed-in grid requirements.
Silent & Maintenance-Free Operation:Natural cooling design (no external fans) ensures quiet operation under <25 dB, ideal for home environments.
Integrated Protection:Built-in DC switch, Type II AC/DC surge protection, anti-islanding, and ground fault monitoring.
Compact & Lightweight Form Factor:Weighing under 5 kg, the ultra-compact housing allows for easy wall-mount installation by a single technician.
