Powering Agricultural Sustainability with the AlphaESS StaX-M50

Discover how Immersa and Natural Generation delivered one of the UK’s first AlphaESS StaX-M50 commercial battery storage systems.

The AlphaESS StaX M50 delivers advanced battery storage solutions for the agri sector

Working alongside energy storage specialist Immersa and renewable energy installer Natural Generation, AlphaESS UK supplied one of the UK’s first StaX-M50 commercial battery energy storage systems at Chynoweth Farm, Cornwall. Combining advanced battery storage with solar PV generation, the project demonstrates how agricultural businesses can maximise renewable energy utilisation, reduce grid dependency and future-proof their energy infrastructure.

Battery energy storage is transforming the economics of on-farm renewable energy, enabling agricultural businesses to capture more of the power they generate, reduce reliance on the grid and build greater resilience against future energy costs.

Turning Surplus Solar Generation into a Valuable Energy Asset

For agricultural businesses, maximising the value of renewable energy generation is becoming increasingly important as energy costs continue to fluctuate and pressure grows to improve sustainability performance.

Chynoweth Farm had already invested in significant solar generation capacity but wanted to capture and utilise more of the electricity being produced on site. Without battery storage, surplus solar energy generated during periods of lower demand would otherwise be exported to the grid, limiting the overall value of the renewable energy investment.

Working closely with the client, Immersa developed a solution designed to:

Increase solar self-consumption and reduce reliance on imported grid electricity.
Improve return on investment from renewable energy generation.
Enhance long-term energy resilience.
Create a scalable platform for future growth.
Maximise the use of available grid capacity.

The project required a flexible commercial battery storage solution that integrates seamlessly with the site’s solar PV system while delivering long-term performance and scalability.

Designing a Smarter Energy Storage Solution for Chynoweth Farm

Immersa chose the AlphaESS StaX-M50 platform for its ability to handle large DC-coupled solar setups and flexibility for commercial and agricultural needs. AlphaESS UK supplied the battery storage technology and product expertise, while Natural Generation undertook the installation and commissioning of the complete system.

The solution combined:

100 kWp rooftop solar PV
AlphaESS StaX-M50 commercial battery storage system
144.6 kWh battery storage capacity
85 kWp DC-coupled solar connected directly to the battery inverter
50 kW battery inverter platform

This setup captures excess solar for later use, helping maximise renewable energy use on the farm.

Why AlphaESS StaX-M50?

The StaX-M50 has been designed specifically for commercial and industrial energy storage applications where performance, flexibility and future scalability are essential.

Advanced DC-Coupled Architecture
The StaX-M50 supports up to 200% DC oversizing, allowing up to 100 kWp of solar to connect to the 50 kW inverter, maximising solar use and project value.
Scalable Commercial Energy Storage
The modular design allows businesses to deploy a battery storage system tailored to their current energy requirements while retaining the flexibility to expand capacity as operational needs evolve.
Supporting Grid-Constrained Projects
By intelligently integrating solar generation and battery storage, the StaX-M50 can help improve project viability where grid connection limitations may otherwise limit renewable energy development.
Comprehensive Technical Support
AlphaESS UK works closely with partners such as Immersa and Natural Generation, providing technical guidance, commissioning expertise and ongoing product support whenever required throughout the project lifecycle.

Delivering Measurable Benefits

The completed installation enables Chynoweth Farm to make greater use of the on-site renewable electricity, helping improve energy efficiency and reduce dependence on imported power.

Key benefits include:

Increased solar self-consumption
Reduced electricity imports from the grid
Improved utilisation of renewable energy generation
Enhanced energy resilience and reduced exposure to future energy price volatility
A future-ready energy storage platform capable of supporting expansion

By storing excess solar generation for use when it is needed most, the system helps maximise the long-term value of the site’s renewable energy investment.

Partnership Driving Performance

The Chynoweth Farm project demonstrates the value of collaboration between specialist energy storage providers, installation partners and technology manufacturers.

By combining Immersa’s expertise in battery storage integration, Natural Generation’s installation capabilities, and AlphaESS UK’s advanced commercial energy storage technology, the project has delivered a robust, scalable renewable energy solution tailored to the needs of a modern agricultural business.

As organisations across the agricultural and commercial sectors seek to improve energy resilience and reduce operating costs, projects such as Chynoweth Farm highlight the important role of battery storage in supporting a more sustainable, energy-independent future.

Looking Ahead: Unlocking More Value from Renewable Energy

The Chynoweth Farm installation showcases how advanced battery storage can transform the performance of commercial solar assets.

Through the combination of intelligent system design, high-performance battery technology and experienced project delivery, AlphaESS UK, Immersa and Natural Generation have created a solution that not only maximises renewable energy utilisation today but also provides a scalable platform for future growth.

For agricultural and commercial businesses looking to reduce costs, increase energy independence and strengthen sustainability performance, battery energy storage is rapidly becoming an essential part of the energy transition.
