Specifications
Product description
The Sungrow SG3.0RS Single-Phase Solar Inverter | 3 kW is a next-generation string inverter for homes seeking reliability, safety, and high performance in self-consumption. With two independent MPPTs, a wide operating range, and IP65 protection rating, it makes better use of energy from the early hours of the day and withstands demanding outdoor conditions. It incorporates top-level protections (Type II SPD on DC and AC and optional AFCI function according to regulations) and complete connectivity (Ethernet/WLAN/RS485) to manage the installation from iSolarCloud with I-V analysis and remote diagnostics.
Main features
- Nominal output power: 3,000 W (3,000 VA) at 230 V single-phase.
- Dual MPPT with MPP range 40–560 V; start-up voltage 50 V, minimum 40 V.
- PV input up to 600 V; max. total current 32 A (16 A/16 A) and Isc 40 A (20 A/20 A).
- Max. efficiency of 97.9% and European efficiency of 97.0%.
- Advanced protections: Type II SPD on DC/AC, leakage detection, reverse polarity, and AFCI (optional).
- Connectivity: Ethernet, WiFi, RS485, and DI input for power control; monitoring on iSolarCloud.
Advantages or benefits
- Enhanced safety with SPD on both sides and arc extinction (AFCI) available to minimize risks.
- Higher production thanks to its dual MPPT and low start-up voltage, ideal for rooftops with two orientations.
- IP65 design and C5 anti-corrosion with natural cooling: silent and prepared for outdoor use.
- Quick start and “plug & play” commissioning, with real-time data and cloud-based alarms.
- Integrated PID Zero function to protect modules and maintain long-term performance.
Purpose or applications
Oriented towards small-scale residential self-consumption installations (3 kW), solar pergolas, garages, or rooftops with 1–2 strings. Its dual MPPT facilitates design with different inclinations or orientations, ensuring stability, efficiency, and full control from your mobile device.
