Solis 6kW 4G Single Phase Inverter: High-Capacity Residential Solar Power

The Solis 1P6K-4G-US-APST is a robust 6kW string inverter designed for larger residential solar installations. As a high-output member of the Solis 4G-PLUS series, it is engineered to handle higher-wattage panel strings while maintaining the signature high efficiency of the Solis platform. Featuring Dual MPPT (Maximum Power Point Tracking), this inverter allows for two independent strings of panels, making it the perfect solution for roofs with East-West orientations or varying tilt angles.

Safety and compliance are at the forefront of the 1P6K-4G-US-APST design. It features a fully integrated Arc Fault Circuit Interrupter (AFCI) to proactively detect and mitigate DC arc faults, ensuring your system meets the most modern NEC safety requirements. With its NEMA 4X rated enclosure and natural convection cooling, this 6kW inverter offers silent, reliable performance in any climate.

Key Technical Advantages:

• Maximum Solar Yield: Dual independent MPPT trackers allow for versatile system design, ensuring that shading on one string does not impact the production of the second string.
• High Conversion Efficiency: Boasts a 97.8% peak efficiency and a wide MPPT voltage range (100V–500V), allowing your system to harvest energy even in low-light conditions.
• Code-Ready Safety: Built-in AFCI significantly reduces fire risk and ensures compliance with UL 1741 SB, IEEE 1547-2018, and California Rule 21.
• Silent & Durable: The fanless, natural convection cooling design eliminates a common point of mechanical failure and ensures whisper-quiet operation near living spaces.
• Smart Connectivity: Fully compatible with Solis WiFi, LAN, or Cellular monitoring sticks for real-time system tracking via the SolisCloud app.
• Weatherproof Reliability: NEMA 4X (IP65) enclosure provides industry-leading protection against dust, rain, and corrosive salt air.
