LuxpowerTek SNA 14K Off-Grid Inverter 14kW single phase off-grid inverter for high-demand residential and commercial systems. Up to 24kW PV input with dual MPPT and high battery throughput for large storage banks. Parallel operation up to 16 units for scalable systems up to well over 100kW. Overview The Fogstar x LuxpowerTek SNA 14K Off-Grid Inverter is built for high-demand off-grid and backup systems, combining 14kW AC output with up to 24kW of PV input and 270A battery charge/discharge capability. It is designed to work with 48V lithium-ion and lead-acid batteries and supports flexible configurations for larger homes and commercial applications. With dual MPPTs, dedicated generator support, fast UPS switching and parallel capability up to 16 units, the SNA 14K provides a powerful and scalable platform for reliable energy supply. It can be used purely off-grid or as part of an “eco hybrid” architecture where solar, generator and grid (where present) can be coordinated to meet site demand. Key features Rated output power 14000W at 230V single phase with sine wave output for sensitive loads. Max. PV input power 24000W (12000/12000) with two independent MPPT inputs and wide 100–480V DC input window. High battery throughput with 270A max. charge/discharge current at 48/51.2V, suitable for large 48V battery banks. UPS switching time <10ms plus overload handling up to 1.5 × rated power for short durations. IP20 wall-mount inverter with smart cooling, integrated breakers and remote monitoring via LuxpowerTek app, RS485, Wi‑Fi and CAN. Typical applications Ideal for high-demand off-grid homes, large rural properties, workshops, small commercial premises and sites currently running large generators. With suitable Fogstar 48V batteries, it can provide long runtimes for HVAC, refrigeration, IT, lighting and process loads, with generator support where needed. Recommended Fogstar battery Best overall: Fogstar Energy 48V 32kWh – balanced capacity and performance for most high-demand residential and off-grid systems. Premium option: Fogstar Energy 48V 48.3kWh Modular Battery – maximum storage for extended runtimes and heavy usage in large homes or commercial sites. Scalable option: Fogstar Energy 48V 16.1kWh / 16.1kWh ECO / 10kWh – modular options to start smaller and expand over time as loads grow.
