Description

The Luxpower SNA14000 14 kW Off-Grid Eco Hybrid Inverter delivers powerful, flexible, and intelligent energy management for large residential, commercial, and off-grid solar + battery systems. Designed to integrate seamlessly with solar PV arrays, batteries, generators, and grid power, this hybrid inverter is ideal for environments where reliable backup power, continuous energy flow, and smart control are essential.

With 2 MPPT controllers handling up to 24 kW of PV input, this inverter maximises solar energy harvest, even in challenging panel configurations. Each MPPT supports two PV strings for flexible string design and optimal performance. The unit supports high-current charging/discharging up to 250 A, making it compatible with large battery banks — whether lithium-ion or lead-acid — for efficient energy storage and delivery.

The SNA14000 includes dual AC output ports for essential and non-essential loads, a dedicated generator port with auto start/stop control, and integrated load and battery breakers for protection and convenience. It also features auto wake-up from PV, AC, or generator input, enabling adaptive power supply depending on available energy resources and system priorities.

Built-in Wi-Fi remote monitoring and flexible operating modes allow you to customise charge and load priorities, track system performance, and diagnose issues remotely. With pure sine wave output, fast transfer times (<10 ms), and robust efficiency, the Luxpower SNA14000 ensures reliable backup and continuous power even during outages.
