Solis 10kW 4G Single Phase Inverter: Maximum Power with Quad MPPT Flexibility

The Solis 1P10K-4G-US-APST is a high-capacity 10kW string inverter engineered for large-scale residential and light commercial solar installations. As the most powerful unit in the Solis 4G-PLUS series, it features an industry-leading Quad MPPT (4 independent trackers). This advanced design allows for four separate panel orientations or string lengths, making it the ultimate solution for complex rooftops that require maximum energy harvest from every angle.

Safety is built into every component, featuring a SunSpec certified module-level rapid shutdown transmitter and an integrated Arc Fault Circuit Interrupter (AFCI). These built-in features ensure your system is fully compliant with the latest NEC 690.12 requirements while providing proactive protection against fire risks. Despite its massive 10kW output, the fanless natural convection cooling design ensures silent and maintenance-free operation for decades.

Key Technical Advantages:

• Quad MPPT Tracking: Four independent trackers provide unmatched flexibility for multi-faceted roofs, ensuring shading on one section never compromises the output of the others.
• High Current Input: Supports up to 14A per string, making it compatible with the latest generation of high-power bifacial and 400W+ solar modules.
• Modern Code Compliance: Fully certified to UL 1741 SB and California Rule 21, featuring integrated PVRSS for simplified rapid shutdown installation.
• Optimized Harvest: Ultra-low 120V startup voltage and a wide 100V–500V MPPT range allow the system to produce energy in low-light and early-morning conditions.
• Industrial-Grade Durability: NEMA 4X (IP65) rated enclosure protects internal electronics from moisture, dust, and corrosive environments.
• SolisCloud Monitoring: Real-time data tracking via WiFi, LAN, or GPRS communication sticks for total system oversight from your smartphone.

Technical Tip: For this 10kW unit, a 50A or 60A dedicated double-pole breaker is typically required. Since this model features 4 MPPTs, you can optimize strings for morning, midday, and afternoon peaks across four different roof facets.
