Description
14kW LuxPower SNA-EU 14000 Off-Grid Inverter
The 14kW LuxPower inverter is a high-capacity single-phase energy solution designed for properties with demanding electrical loads. It is suitable for large residential solar systems, farms, workshops, offices and small commercial properties requiring dependable backup or off-grid power.
With a continuous output capacity of 14,000W, the LuxPower SNA-EU 14000 can support multiple household or business appliances when the system is correctly designed. Its pure sine wave output provides stable power for sensitive electronics, motors, pumps, refrigeration and other essential equipment.
High Solar Input With Dual MPPT Technology
The LuxPower 14kW inverter features two independent MPPT solar charge controllers with four PV strings. It supports up to 24kW of total solar-panel input, allowing the system to produce more power during the day while supplying loads and charging the batteries.
The two MPPTs also make it easier to divide solar panels across different roof orientations or panel arrays while maintaining efficient solar production.
Powerful 48V Battery Charging
The LuxPower SNA-EU 14000 works with compatible 48V lithium-ion and lead-acid battery banks. It supports battery communication through CAN and RS485 and provides up to 250A charging and discharging current.
For the best performance, the inverter should be paired with a properly sized high-capacity battery bank capable of safely delivering the required current.
Dedicated Generator Support
A separate generator input allows the inverter to work with a compatible backup generator. The system can use generator power to supply loads and recharge the batteries when solar or grid power is unavailable.
Its generator control features make the 14kW LuxPower inverter suitable for farms, remote properties and businesses requiring longer backup periods.
Smart Load Management
The inverter includes dedicated load and smart-load outputs, allowing selected appliances or non-essential circuits to be managed according to available solar power, battery capacity and system settings.
This helps prioritise essential equipment while controlling larger loads such as geysers, pumps and other high-consumption appliances.
Remote LuxPower Monitoring
Built-in communication support allows the system to be monitored through the LuxPower mobile app and online platform. Users can view solar production, battery charge level, household consumption and inverter operating status remotely.
Compatible communication equipment also allows authorised technicians to adjust settings, perform diagnostics and install supported firmware updates remotely.
