LuxpowerTek SNA 6K Off-Grid Inverter 6kW single phase off-grid inverter for sites with weak, unreliable or no grid supply. Intelligent off-grid and hybrid modes, with seamless switching and wide PV input voltage range. Scalable design – support for up to 16 units in parallel for systems from 3kW to around 50kW. Overview The Fogstar x LuxpowerTek SNA 6K Off-Grid Inverter is part of the SNA 3–6kW series, designed for areas where grid power is unstable or scarce. It can operate as a pure off-grid inverter or in hybrid mode, supporting solar and utility jointly taking the load and allowing you to choose between self-consumption and charge-priority operation. The SNA 6K supports paralleling of up to 16 inverters, enabling systems from 3kW to 50kW for residential, agricultural and small commercial applications. It provides seamless off-grid switching, a separate generator port and good battery compatibility with 48V lithium-ion and lead-acid batteries. Key features Intelligent off-grid and hybrid modes with seamless switching between sources. Wide PV input voltage range with dual MPPT, and support for single phase or unbalanced 3‑phase systems via parallel operation. Separate generator port and host inverter auto-generation to manage multi-inverter systems. Compatible with lithium-ion and lead-acid batteries at 48V nominal, including force wake-up from PV and grid. Compact wall-mount design (303 × 505 × 135 mm) with LCD+LED display and RS485/Wi‑Fi/CAN communications. Typical applications Suitable for off-grid homes, cabins and holiday lets, farms, remote workshops and telecoms sites where diesel generators are currently used. It can act as backup power or replace generators, using solar and batteries to reduce running costs and noise. Technical specifications PV input (DC) Max.
