S6 4.6kW 2MPPT 1PH Inverter - with DC

Solis S6 4.6 kW 2-MPPT 1-Phase Inverter (with DC)

Ideal for residential rooftop solar installations

Overview
The Solis S6 4.6 kW inverter is part of the latest Series 6 lineup from Solis, crafted specifically for small to mid-sized residential grid-tied PV systems. With dual MPPT (Maximum Power Point Tracking) inputs and a broad DC input range, it’s optimized for flexible panel layouts and modern rooftop conditions. 

Key Specifications & Features

• Rated AC output: 4.6 kW single-phase. 

• Dual MPPT design enables two independent string groups for better yield when panels face different directions or have minor shading.

• Maximum DC input (PV array) power up to approx 6.9 kW. 

• Wide DC input voltage range: Start-up voltage at ~120 V, maximum DC input voltage up to ~600 V

• High conversion efficiency: Max efficiency ~97.6%, European efficiency ~97.1%. 

• Integrated protective features:

  • AFCI (Arc-Fault Circuit Interrupter) on DC side to reduce fire risk. DC switch and reverse-polarity protection, short-circuit/over-current protections. 

• Export-limitation/control ready (important for grids with restrictions). Requires external CT clamp for export limiting.

• Enclosure rated IP66 — suitable for outdoor installations in demanding environments. 

• Compliant with South African grid-tie standards (e.g., NRS 097-2-1) and is ideal for our local market. 

Applications & Benefits

• Excellent for residential homes in South Africa where panel arrays can face multiple angles, or have shading challenges: the dual MPPT helps maximize output.

• Its robust design (IP66, integrated protection) makes it suitable for outdoor wall-mounting in harsh climates.

• Streamlines installation with modern safety and grid-compliance features built-in, lowering the need for bespoke add-ons.

• With a relatively compact size and lightweight build, it's installer-friendly and suitable for retrofit jobs as well as new installations.

Installation Notes / Considerations

• Although rated 4.6 kW output, the PV array can be oversized (up to ~6.9 kW) under suitable conditions. Careful string design is needed to ensure voltage/current are within limits. 

• Export limitation function activates only when correct CT clamp and setup are installed — ensure your installer includes that if required by your utility.

• For optimal yield, design your strings to keep each MPPT operating in its optimum range (i.e., group panels by orientation/tilt/shade) to leverage the dual-MPPT advantage.

• Verify latest firmware, grid-compliance settings (especially for South Africa’s grid code) and monitoring options (WiFi/RS-485) if you want remote data/logging.

Summary
The Solis S6 4.6 kW inverter is a high-value choice for residential solar systems: dual MPPT flexibility, strong efficiency, built-in safety and export-control features make it well suited for modern homes. If you’re looking to highlight a reliable, well-spec’d inverter for the rooftop market — this is a strong contender.
