High-Power Off-Grid Solar and Battery Storage

The SNA 14K is built for larger off-grid energy systems where substantial continuous power and battery throughput are required. With up to 14kW continuous output, it can support considerably higher electrical loads than smaller residential off-grid inverters, making it suitable for properties running multiple appliances, pumps, workshop equipment and other demanding loads.

Its low-voltage battery architecture supports 48V and 51.2V battery storage systems, with up to 270A maximum charge and discharge current. This high battery throughput allows large battery banks to supply substantial loads while also supporting rapid charging when sufficient solar or supplementary power is available.

Up to 24kW Solar PV Input

A maximum solar PV input capacity of 24,000W gives the SNA 14K significant renewable energy harvesting capability. This is particularly valuable in off-grid installations, where generating sufficient energy during available daylight hours is critical to maintaining battery state of charge and reducing dependence on generator power.

Dual MPPT inputs allow separate solar arrays or different roof orientations to be managed independently. Maximum MPPT efficiency of 99.0% helps maximise available solar energy as irradiance and operating conditions change throughout the day.

Generator Integration and Backup Power

A dedicated generator port with automatic start and boost functionality allows a generator to form an integrated part of the off-grid energy system. This provides an additional source of power when solar generation is insufficient or when unusually high electrical demand needs to be supported.

Automatic generator functionality is particularly valuable for remote and fully off-grid properties, where maintaining battery state of charge during prolonged periods of poor weather can be essential. Solar generation remains the primary renewable energy source while generator capability provides an additional layer of resilience.

Dual AC Outputs and Fast Transfer

Dual AC outputs provide additional flexibility when connecting and managing loads within a larger off-grid installation. This can help installers separate different load groups and build a more practical power distribution arrangement around the inverter.

A transfer time of less than 10ms helps maintain continuity of supply when switching power sources, while pure sine wave output provides clean AC power suitable for sensitive electronics, communications equipment and household appliances.

Scalable Parallel Operation

Up to 16 SNA 14K units can operate in parallel, giving the platform significant expansion potential for larger off-grid and high-load energy storage projects. This allows an installation to grow beyond the capability of a single 14kW inverter where additional power capacity is required.

Combined with high solar input and substantial battery throughput, this scalability makes the SNA 14K suitable for demanding renewable energy projects where future expansion needs to be considered from the outset.
