Product Description

The Solis S5-GC25K Three-phase 25kW On-Grid Solar Inverter is a professional string inverter for commercial and tertiary installations that require high performance, safety, and real-time data. With 3 independent MPPT and 6 total inputs, it allows the design of systems with multiple orientations or partial shading, maintaining a maximum efficiency of 98.5% and a European efficiency of 98.1%. Its IP66 protection rating and redundant fan cooling ensure outdoor reliability, while AFCI arc protection and Type II SPD on DC/AC reinforce electrical safety.

Main Features

3 MPPT / 6 strings for greater flexibility on E/W roofs or with different inclinations.
Max. efficiency 98.5% (EU 98.1%) and THDi < 3% for clean energy delivery.
Wide MPPT range 200–1000 V, start-up voltage 180 V and U_DC max. 1100 V.
16 A per string (I_sc 20 A) and 32 A per MPPT, ready for TOPCon/HJT modules.
String monitoring and I-V curve analysis with SolisCloud; RS485 and Wi-Fi/GPRS option.
Supports export control and DC/AC oversizing up to 150%.

Advantages or Benefits

Higher annual production thanks to 3 MPPT and high photovoltaic oversizing.
Proactive O&M: monitors each string and uses I-V scanning to detect anomalies.
Compatibility with high-current panels without input throttling.
Agile installation with MC4 connectors on DC and OT terminals on AC; guided commissioning.
Enhanced safety with AFCI, anti-islanding, Type II SPD, and thermal monitoring.

Purpose or Applications

Ideal for three-phase self-consumption of 25 kW in warehouses, supermarkets, workshops, farms, and office buildings. Allows the design of fields with various orientations and to limit export when required by regulations.
