Solis 7.6kW 4G Single Phase Inverter: Ultimate Efficiency with Triple MPPT

The Solis 1P7.6K-4G-US-APST is a high-capacity 7.6kW string inverter designed for demanding residential solar projects. This "Plus" version is a standout in the 4G series, featuring an industry-leading Triple MPPT (3 independent trackers). This allows for maximum energy harvest on homes with complex rooflines—such as those with panels on South, East, and West faces—without the losses typically associated with shading or varying orientations.

Safety is seamlessly integrated with a built-in SunSpec certified module-level rapid shutdown transmitter and an Arc Fault Circuit Interrupter (AFCI). These features ensure your installation is fully compliant with the latest NEC safety codes while providing proactive fire risk mitigation. The NEMA 4X enclosure and natural convection cooling ensure the unit remains silent and durable, even in harsh outdoor environments.

Key Technical Advantages:

• Triple MPPT Design: Three independent trackers provide the ultimate flexibility for complex roof geometries, ensuring each panel string operates at its peak performance.
• High-Current Compatibility: Supports string currents up to 14A, making it fully compatible with the latest high-power and bifacial solar modules.
• Comprehensive Safety: Includes integrated AFCI and a built-in Rapid Shutdown transmitter, simplifying NEC 690.12 compliance for installers.
• Exceptional Efficiency: Boasts a 97.5% CEC weighted efficiency and an ultra-low 120V startup voltage to maximize daily energy production.
• Silent & Weatherproof: Fanless, natural convection cooling within a NEMA 4X (IP65) enclosure provides whisper-quiet, maintenance-free operation in any climate.
• Advanced Monitoring: Real-time system tracking via SolisCloud with optional WiFi, LAN, or Cellular communication sticks.

Technical Tip: Due to the 31.7A output, this inverter typically requires a 40A dedicated double-pole breaker. For installs utilizing the Triple MPPT feature, ensure your conduit fill calculations account for three separate DC string pairs.
