Modelo: SG12RT- Sku: SUNGINV019
- Vendor: Sungrow
Specifications
Product Description
The Sungrow SG12RT Three-Phase Solar Inverter | 12 kW is a high-performance string inverter for three-phase self-consumption that prioritizes efficiency, safety, and professional connectivity. Its optimized electronics, dual MPPT input, and compatibility with bifacial modules allow for maximum daily production, while its IP65 housing with C5 corrosion resistance ensures reliability outdoors and in coastal environments. Integration with iSolarCloud offers advanced monitoring, guided commissioning, and predictive maintenance to reduce downtime.
Main Features
- Nominal AC power: 12 kW three-phase (3/N/PE, 230/400 V, 50 Hz) with adjustable power factor and export control.
- PV architecture at 1000 Vdc: maximum input voltage 1100 V and wide MPPT range of 160–1000 V for multiple string configurations.
- 2 independent MPPTs with intelligent I-V scanning, ideal for rooftops with different orientations or partial shading.
- Maximum reference efficiency: 98.5% (typical European ~97.6%), reducing internal losses and improving energy yield.
- Comprehensive safety: AFCI for arc detection, PID Recovery function, anti-islanding, and Type II SPD on both DC and AC sides.
- Professional-grade connectivity: WiFi, Ethernet, and RS485, DI/DO, and centralized management in iSolarCloud with OTA updates.
Advantages or Benefits
- More usable kWh thanks to high performance and stable MPPT tracking over a wide voltage range.
- Operational continuity: active protections (AFCI, SPD II) and PID recovery minimize incidents and downtime.
- Quick and clean installation with compact design, push-in connectors, and commissioning assistant via app.
- Reduced O&M costs through remote diagnostics (I-V curve), alarms, and remote firmware updates.
- Silent operation with natural cooling, suitable for installation near inhabited areas.
Purpose or Applications
Focused on advanced residential three-phase self-consumption and SMEs with high daytime demand (air conditioning, cameras, light machinery, electric vehicle chargers). Its IP65 and C5 rating allow installation outdoors in protected and coastal environments.
