      Off-Grid Ready with Hybrid Flexibility
      Reliable Energy for Off-Grid and Weak-Grid Areas

      SNA 3–6K provides stable power in off-grid or unstable-grid conditions. Its hybrid-ready design allows seamless integration of solar PV, batteries, grid, and generator inputs for flexible, cost-effective energy control.

      Efficient Solar Harvesting
      Dual MPPT with Wide PV Input Range

      Two independent MPPTs support up to 9.6 kW PV input. Capture more energy under diverse roof orientations and partial shading.

      Intelligent Dispatch
      Time-of-Use and AI Energy Optimization

      Prioritize self-consumption and reduce energy costs. AI-driven charge and discharge strategies optimize energy flow and maximize savings.

      Generator Support
      Automatic Generator Control

      When solar and battery energy are low, the inverter can automatically trigger a generator for seamless power supply and battery recharge.

      Remote Monitoring & Service User-Friendly LuxCloud App

      Check real-time PV output, battery status, and power usage anytime. Change settings and receive firmware updates with ease — from your phone or computer.

      Built to Last Engineered for Challenging Environments

      With an IP20-rated enclosure and optimized thermal design, SNA 3–6K ensures stable performance in typical indoor and semi-sheltered installation sites.
