Product description

The Sungrow SG2.5RS-S Single-Phase Solar Inverter | 2.5 kW is designed to maximize the performance of small residential installations. Its transformerless topology, wide MPPT operating range, and integrated protections (Type II SPD on DC and AC, and AFCI) provide efficient and safe operation. Ethernet/WLAN/RS485 connectivity and the iSolarCloud platform enable professional monitoring with I-V analysis and remote diagnostics to minimize downtime.

Main features

Nominal output power: 2,500 W (2,500 VA) at 230 V single-phase.
1 MPPT with MPP range of 40–560 V; starts at 50 V to capture energy from the early hours.
PV input: max. voltage 600 V; max. current 16 A; max. Isc 20 A.
Max. efficiency up to 97.2%; THD < 3% and power factor > 0.99.
Protection rating IP65, C5 anti-corrosion housing, and natural cooling (silent).
Comprehensive connectivity: Ethernet / WLAN / RS485 / DI; real-time data and alarms.

Advantages or benefits

Enhanced safety with Type II SPD on both sides and arc detection/extinguishing (AFCI).
Greater energy yield thanks to the wide MPP range and low start-up voltage.
Plug & play installation and quick commissioning with guides and tools in iSolarCloud.
Compact design (A4 size) and 6 kg, ideal for wall mounting and limited spaces.
Intelligent management with I-V diagnostics to resolve issues without unnecessary travel.

Purpose or applications

Perfect for homes with 1 string of high-power or bifacial modules, solar pergolas, and small rooftops seeking reliability, ease of use, and 2.5 kW of power optimized for self-consumption.
