Product Description

The Solis S5-GC40K Three-phase 40kW On-Grid Solar Inverter is the highest power option in the GC series for commercial and industrial rooftops. With 4 MPPT (8 inputs), it allows the generator to be segmented into several subfields and reduces losses due to orientation or shading. The maximum efficiency of 98.7%, wide MPPT range, and IP66 chassis with intelligent ventilation ensure stable outdoor operation. It incorporates AFCI, string monitoring, and I-V curve scanning for predictive O&M, as well as compatibility with export control (zero feed-in) and optional PID recovery.

Main Features

4 MPPT / 8 strings for maximum flexibility on complex rooftops and carports.
Max. efficiency 98.7% (EU ≈98.3%) and THDi < 3%.
MPPT range 200–1000 V, start-up voltage 180 V, and max. U_DC 1100 V.
16 A per string (admissible I_sc 20 A) and 32 A per MPPT: suitable for high-current TOPCon/HJT modules.
DC/AC oversizing up to 150% to improve the plant factor.
RS485 communications and Wi-Fi/GPRS option in SolisCloud for alarms and remote diagnostics.

Advantages or Benefits

Superior production by independently managing four PV zones with different irradiance.
Proactive O&M: string monitoring and I-V scanning detect soiling, PID, or string faults.
Robust outdoor design: IP66 enclosure and redundant fans for demanding climates.
Professional installation: MC4 on DC, OT terminals on AC, and commissioning assistant from the LCD.
Advanced safety with AFCI, Type II SPD on DC/AC, anti-islanding, and thermal control.

Purpose or Applications

Ideal for three-phase self-consumption of 40 kW in light industry, logistics, agri-food, supermarkets, and tertiary buildings. Suitable for projects with surplus compensation or zero feed-in and for large rooftops with multiple orientations.
