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 IP21-rated enclosure and optimized thermal design, SNA 3–6K ensures stable performance in typical indoor and semi-sheltered installation sites.
