Solis Solar Inverter 100K-5G-PRO Three-Phase 100kW On-Grid

Product description

The Solis 100K-5G-PRO Three-Phase 100kW On-Grid Solar Inverter is an industrial string inverter designed to maximize production and reduce operating costs in large self-consumption installations. With 10 MPPT and up to 20 strings, it allows the photovoltaic generator to be segmented into multiple zones with different orientations, shading, or inclinations, reducing mismatch losses and increasing the annual energy yield. Its high-performance electronics achieve a maximum efficiency of 98.7% (EU 98.3%), while the IP66 chassis and redundant fan cooling ensure reliability outdoors. It features AFCI for arc detection, Type II SPD on DC/AC, I-V curve scanning, and string monitoring for predictive O&M. In addition, it offers optional PID recovery and RS485 communication with Wi-Fi/GPRS/PLC options for monitoring in SolisCloud.

Main features

• 10 MPPT / 20 strings for complex designs with multiple roof sections and partial shading.
• MPPT range 180–1000 V (start-up 195 V) and max. U_DC 1100 V for long strings.
• Input per MPPT: 26 A (I_sc max. 40 A) compatible with TOPCon/HJT and bifacial modules.
• Max. efficiency 98.7 %, power factor >0.99 (0.8 cap…0.8 ind), and THDi <3 %.
• Nighttime SVG function and possibility of DC/AC oversizing ≥150 %.
• Advanced diagnostics: string-level monitoring and integrated I-V curve analysis.

Advantages or benefits

• Higher annual production thanks to high efficiency, wide MPPT range, and the possibility to oversize the PV array to improve the plant factor.
• True design flexibility: ten independent MPPTs allow optimization of areas with different orientations, inclinations, and irradiance conditions.
• Proactive O&M: I-V scanning and string monitoring detect soiling, PID, or string faults within minutes, reducing downtime.
• Industrial safety with AFCI (activation required), anti-islanding, and Type II SPD on DC/AC; optional AC Type I for demanding environments.
• Simple integration with standard RS485 and optional Wi-Fi/GPRS/PLC modules for remote management in SolisCloud and export control (zero feed-in).
• Weatherproof robustness: IP66 enclosure and intelligent fans for stable operation in hot or dusty climates.

Purpose or applications

Focused on large industrial rooftops, solar car parks, logistics centers, agri-food facilities, and tertiary buildings with high demand and the need for string-level monitoring. Perfect for high-power three-phase self-consumption, projects with surplus compensation or zero feed-in regulations, and plants requiring advanced diagnostics and high availability.

Technical specifications

Compatibilities

Compatible with high-power monofacial and bifacial photovoltaic modules within electrical limits; Wi-Fi/GPRS/PLC connectivity modules for SolisCloud; meters/relays via RS485 and export control solutions (zero export). Supports “Y” connectors on the DC side when required by the design.

The Solis 100K-5G-PRO Three-phase 100kW On-Grid Solar Inverter is the professional platform for large-scale projects that demand maximum efficiency, advanced diagnostics, and IP66 reliability with 10 MPPT.
