Product Description

The Solis S5-GR3P12K Three-Phase 12kW On-Grid Solar Inverter increases power while maintaining the high-performance platform of the S5 series. Its dual MPPT with 4 strings supports high-current modules, while the 98.7% efficiency, wide MPPT range, and IP66 protection rating provide more energy and reliability outdoors. It incorporates AFCI for arc fault protection and RS485/Wi-Fi communications for agile remote monitoring and diagnostics.

Main Features

Nominal AC power: 12 kW (13.2 kVA max.) at 3/N/PE 230/400 V; 50/60 Hz.
2 MPPT / 4 strings (2 per MPPT) to combine two orientations or subfields.
DC input up to 1100 V; MPPT range 160–1000 V; startup 180 V.
16 A per string (I_sc allowable 20 A), suitable for TOPCon/HJT modules.
Max. efficiency 98.7%; European efficiency ~98.2%; THDi < 2%.
Supports up to 150% photovoltaic oversizing (DC/AC).

Advantages or Benefits

Greater consumption coverage and better capacity factor for demanding businesses and homes.
Optimized production with 2 independent MPPTs for E/W roofs or with partial shading.
Simple installation and O&M: MC4 connectors, natural convection, and SolisCloud for alerts and data.
Enhanced safety with AFCI, anti-islanding, and comprehensive electrical protections.
Outdoor robustness: IP66 weatherproof enclosure.

Purpose or Applications

Ideal for three-phase self-consumption in businesses, workshops, offices, or large homes. Perfect when export limitation is required or when designing long strings with high input voltage and startup at 180 V.
