Off-Grid Solar and Battery Power
The SNA 6K is built for systems where dependable battery-backed AC power is a priority. Its 48V / 51.2V battery architecture allows it to integrate with Fogstar battery storage while supporting high charge and discharge currents of up to 140A.
With 6kW of continuous output and up to 12kW surge power for 5 seconds, the inverter can handle demanding household and off-grid loads while still providing the short-duration power needed by equipment with higher start-up requirements.
High Solar Input with Dual MPPTs
Up to 9,600W of solar PV input allows the inverter to support larger solar arrays, while dual MPPT trackers provide improved flexibility when panels are installed across different roof orientations, array sections or ground-mounted strings.
Maximum MPPT efficiency of 99.9% helps the system capture available solar energy efficiently across changing conditions, making it a strong choice for off-grid solar systems where maximising daily energy harvest is especially important.

Generator and Hybrid System Support
The SNA 6K supports generator integration alongside AC coupling and smart load functionality, giving installers greater flexibility when building complete off-grid or hybrid energy systems. This makes it suitable for applications where solar and battery storage may need to work alongside a generator or alternative AC power source.
Fast transfer between grid and off-grid operation helps maintain continuity of supply, while pure sine wave output provides clean AC power for sensitive electronics, appliances and communications equipment.
Scalable Parallel Operation
Up to 18 units can be operated in parallel, providing substantial expansion potential for larger off-grid solar and battery storage systems. This makes the platform suitable not only for residential installations, but also for larger properties, workshops, remote buildings and commercial off-grid applications where greater power capacity may be needed.
