Product Description

The Sungrow SG50CX-P2 Three-Phase Solar Inverter | 50 kW is a professional 1000 Vdc string inverter designed for commercial and industrial three-phase installations that require maximum performance, advanced safety, and intelligent O&M. With 4 independent MPPTs and 8 inputs (2 per MPPT), it optimizes rooftops with different orientations or partial shading. The high-efficiency electronics (up to 98.5%) reduce internal losses, while the IP66 protection with C5 corrosion class ensures reliability outdoors and in coastal areas. It incorporates AFCI 2.0, SPD DC Type I+II, and SPD AC Type II, as well as PID recovery function and intelligent I-V curve diagnostics to maintain stable production and facilitate preventive maintenance via iSolarCloud.

Main Features

Nominal AC power: 50 kW three-phase, maximum apparent power 55 kVA for demand peaks.
PV architecture of 1000 Vdc with maximum input voltage 1100 V and MPPT range of 160–1000 V.
4 MPPT / 8 strings (2 per MPPT), ideal for multi-pitched roofs and bifacial modules.
Maximum DC current: 120 A (30 A × 4); max Isc: 160 A (40 A × 4); DC connector up to 30 A.
Maximum efficiency 98.5% (European 98.3%) and night consumption < 7 W for more usable kWh.
Safety: AFCI 2.0, anti-islanding, string current monitoring, PID recovery, SPD DC Type I+II, and SPD AC Type II.

Advantages or Benefits

Higher annual production thanks to 4 MPPTs that minimize losses due to mismatches and partial shading.
High availability: active protections (AFCI 2.0 and SPD I+II/II) and intelligent IV diagnostics that detect issues before they affect performance.
Fast and tidy installation: moderate weight (~41 kg), plug & play, AC terminals for Al/Cu cable, and “buckle” design.
Reliable outdoor operation: IP66, C5 class, and intelligent forced cooling to maintain power in hot climates.
Simplified O&M: iSolarCloud with 24/7 monitoring, alarms, grid fault logs, and OTA updates.

Purpose or Applications

Ideal solution for three-phase self-consumption in industrial buildings, businesses, farms, solar car parks, and SMEs with high daytime demand (air conditioning, cold storage, processes, and electric vehicle chargers). Its multi-MPPT architecture allows adaptation to complex roofs with different slopes and orientations.
