SNA-12KW Datasheet

⚡LuxPower SNA 12K – 12 kW Single-Phase Hybrid Inverter with Dual MPPT, <10 ms UPS Transfer & Dedicated Generator Port

A robust hybrid inverter that unifies PV + battery + grid with a dedicated generator/AC-coupling input. It supports half-wave loads, achieves ultra-fast backup transfer (<10 ms, single or parallel), continuous AC passthrough up to 100 A, and PV input up to 24 kW. Smart Load and EPS outputs each support up to 12 kW in on-grid mode—ideal for GCC & Middle East sites with mixed sources and sensitive loads.

🌍 Why SNA 12K Fits the GCC & Middle East

  • 🌦️ Instant continuity: <10 ms UPS transfer safeguards sensitive loads (IT racks, pumps, refrigeration) during grid dips.
  • 🔌 High coupling flexibility: PV + grid + battery + dedicated GEN/AC-coupling, with Smart Load & EPS outputs up to 12 kW each in on-grid mode.
  • 📈 Better yield across the day: 120–385 V MPPT range captures more energy in mornings/evenings and under high-temperature conditions.
  • 🛠️ Built for challenging grids: half-wave load support, 100 A passthrough, and stable operation for intermittent networks common in the region.

🏭 Application Scenarios

  • 🏠 Homes & villas needing true-UPS behavior with battery storage.
  • 🏪 Shops, offices, workshops, and warehouses with mixed sources (PV + grid + generator).
  • 🏭 Off-grid and small/medium commercial projects across Saudi Arabia, UAE, Oman, Qatar, Bahrain, Kuwait, and Yemen.
