Solis S5-GC50K 50kW three-phase on-grid inverter
Modelo: S5-GC50K- Sku: SOLIINV025
- Vendor: Solis
Specifications
Product Description
The Solis S5-GC50K 50kW three-phase on-grid inverter is a high-performance industrial string inverter for large commercial rooftops. Its architecture with 5 MPPT (10 inputs) allows the generator to be divided into several subfields with different orientations, reducing mismatch losses and maximizing annual production. With a maximum efficiency of 98.7% (EU 98.3%), IP66 C5 enclosure, and intelligent redundant ventilation, it ensures reliability outdoors and stable operation in demanding climates. It incorporates AFCI, SPD Type II on DC/AC, and thermal monitoring, as well as advanced features such as string monitoring, I-V curve scanning, nighttime SVG, and export control for zero feed-in.
Main Features
- Nominal power 50 kW (55 kVA/55 kW max.) at 3/N/PE 220/380–230/400 V, 50/60 Hz.
- 5 MPPT / 10 strings for complex designs with multiple roof sections or obstacles.
- MPPT range 180–1000 V (start-up 195 V), UDC max. 1100 V; supports long strings.
- Current per string up to 16 A; per MPPT 32 A (Isc per MPPT 40 A).
- 98.7% efficiency, THDi < 3% and PF > 0.99 (0.8 cap…0.8 ind).
- Advanced O&M: string monitoring, I-V scanning, remote update and control via SolisCloud.
Advantages or Benefits
- Higher annual energy with 5 MPPT and possibility of 150%+ DC/AC to improve plant factor.
- Predictive diagnostics per string that accelerates detection of soiling, PID, or faults.
- Compatibility with high-current TOPCon/HJT modules without throttling.
- Outdoor robustness: IP66 with C5 anti-corrosion protection and redundant fans.
- Industrial-grade electrical safety: AFCI, SPD II DC/AC, anti-islanding, and comprehensive protections.
Purpose or Applications
Three-phase self-consumption of 50 kW in warehouses, supermarkets, agro-industry, solar car parks, and tertiary buildings, with or without feed-in limitation. Ideal when several PV fields with different behavior are required.
