Solis S6 125kW 3 Phase Grid-Tied Inverter

Solis Three-Phase Grid-Tie String Inverter

Commercial solar workhorse for large-scale C&I installations in Southern Africa converting maximum PV energy into clean grid power with outstanding efficiency and intelligence. NRS 097-2-1:2024 certified for South African grid connection and manufactured by Ginlong to IEC standards, the S6-GC125K delivers 10 independent MPPTs, 98.7% peak efficiency, and a flexible parallel architecture in an IP66 package built for Southern African conditions.

Key Features & Specifications:

Ten Independent MPPTs for Maximum Commercial Yield

Ten dedicated solar trackers across 20 string inputs independently optimise energy harvest regardless of module orientation, shading, or mismatch. With a 42A max input current per MPPT and a 160–1000V working range, the S6-GC125K accommodates the latest high-power commercial modules in any large array layout.

98.7% Peak Conversion Efficiency

Industry-leading energy conversion means more kilowatt-hours from every watt of installed PV; directly improving the financial return on commercial solar investments over a 20+ year system lifetime.

NRS 097-2-1:2024 Grid Certified

TÜV Rheinland certified to South Africa's latest SSEG grid connection standard, ensuring full compliance for utility interconnection, municipal feed-in, and Eskom grid connection applications; removing compliance risk from large commercial projects.

Parallel Scalability up to 1.25MW

Up to 10 units operate in a master-slave configuration without an external controller, scaling from 125kW to 1.25MW. Optional three-phase unbalanced output control allocates power per phase on demand for flexible grid compatibility.

AFCI Safety with Real-Time PV Monitoring

AI-based millisecond arc fault detection (AFCI 2.0, optional) and real-time PV grounding detection identify hazards before they escalate; with optional Rapid Shutdown (RSD) co-operation for enhanced fire safety on commercial rooftop installations.

Export Power Management & Generator Integration

Built-in EPM controls solar export for self-consumption and anti-reverse flow compliance. Supports single and multiple genset applications natively; no external controller needed.

IP66 All-Weather Enclosure with Intelligent Fan-Cooling

Fully sealed against dust and high-pressure water, rated for outdoor installation across Southern Africa's coastal, highveld, and bushveld conditions; intelligent fan-cooling maintains optimal temperature during peak generation hours.

Warranty Protection Solis Inverter:

• 5-year standard product warranty
• 10-year extended warranty available, purchasable via the SolisCloud app or through your authorised Solis distributor
• T&C may apply.

The Solis S6-GC125K Three-Phase Grid-Tie Inverter delivers the efficiency, grid compliance, and scalability that Southern African commercial and agricultural solar installations demand. Whether maximising self-consumption for a factory or warehouse roof, building a large commercial PV plant, or scaling to multi-unit installations up to 1.25MW, the S6-GC125K is NRS-certified and ready.
