Specifications
Product Description
The Sungrow SG15RT Three-Phase Solar Inverter | 15 kW is a 1000 Vdc string inverter designed for three-phase installations that demand performance, safety, and advanced control. With dual MPPT, a wide tracking range, and industrial-grade protection features, it maximizes daily production and safeguards the plant’s lifespan. Its IP65 enclosure with C5 corrosion resistance, push-in connectors, and app-guided commissioning enable quick and reliable installation, while iSolarCloud allows for remote analysis and maintenance.
Main Features
- Nominal AC power: 15 kW three-phase (3/N/PE, 230/400 V) with export control and adjustable power factor.
- PV architecture of 1000 Vdc: maximum input voltage 1100 V; MPPT range 160–1000 V and start-up voltage ≈180 V.
- 2 independent MPPT / 2 strings (typical), max. PV current 50 A (25 A per MPPT) and max. Isc 64 A (32/32 A).
- Reference efficiency: up to 98.5% (European ~98.1%) for greater energy yield.
- Comprehensive safety: AFCI, anti-islanding, DC reverse polarity protection, overvoltage protection, and Type II SPD on DC/AC.
- Professional connectivity: WiFi, Ethernet, and RS485, DI/DO inputs/outputs, and full integration with iSolarCloud.
Advantages or Benefits
- More annual kWh thanks to the wide MPPT range, high efficiency, and compatibility with bifacial modules.
- High availability due to active protections (AFCI, SPD II) and PID Recovery function that stabilizes performance.
- Quick installation: 21 kg, push-in connectors, “plug & play” AC, and app-guided commissioning.
- Predictive maintenance with I-V curve analysis, alarms, and OTA updates from iSolarCloud.
- Controlled operation: intelligent forced cooling and typical noise level of 45 dB.
Purpose or Applications
Ideal for three-phase self-consumption in large homes, businesses, and SMEs with high daytime consumption (air conditioning, cameras, light machinery, EV chargers). Its IP65/C5 rating allows for protected outdoor installation and use in coastal environments.
