Product Description

The Solis S5-GR3P6K Three-Phase 6kW On-Grid Solar Inverter delivers extra power while maintaining the same reliable and secure platform of the S5 series. Its dual MPPT with 16 A per input supports next-generation panels, while the 98.6% efficiency, DC oversizing up to 150%, and IP66 enclosure ensure performance and durability. Includes arc protection (AFCI), anti-islanding, and RS485 communications with Wi-Fi/GPRS option for remote management and diagnostics.

Main Features

Nominal AC power: 6 kW (6.6 kVA max.) on 3/N/PE 230/400 V, 50/60 Hz.
2 MPPT / 2 strings; flexible design for two orientations or subfields.
PV input: up to 1100 V; MPPT range 160–1000 V; startup 180 V.
Current per MPPT: 16 A (admissible Isc 20 A) suitable for TOPCon/HJT modules.
Max. efficiency 98.6%; European efficiency ~98.0%; THDi <2%.
Compatible export control (feed-in management) and integration with SolisCloud.

Advantages or Benefits

Greater consumption coverage for homes with heat pumps or small businesses.
Optimized production even with variable irradiance and E/W roofs thanks to 2 MPPT.
Compatibility with high-current panels up to 16 A per string.
Quick and silent installation with natural convection, MC4, and fast AC plug.
Enhanced safety: AFCI, anti-islanding, and comprehensive electrical protections.

Purpose or Applications

Designed for three-phase self-consumption in high-demand homes, offices, workshops, and SMEs. Ideal for projects with feed-in limitation requirements and for designing long strings thanks to its high input voltage and 180 V startup.
