Solar Battery Storage Systems


High-performance solar battery storage systems, designed for residential and commercial & industrial (C&I) projects, offer seamless integration, flexible sizing, and full compliance with UK standards. Alternergy supplies these systems to UK installers with expert support and reliable delivery.

We partner with leading global brands – including Dunext, Huawei FusionSolar, Sungrow, Growatt, and Fox ESS – to deliver battery storage solutions that maximise energy efficiency and suit a variety of property sizes, energy usage profiles, and project budgets.


Explore Battery Storage Solutions

All our solutions are available to the trade, with competitive pricing and manufacturer-backed technical support, ensuring professional installers have the resources needed for successful solar battery storage project delivery.

They include:

  • Residential battery storage systems: Understanding the customer’s typical energy consumption and peak demand periods helps determine the appropriate battery size and discharge strategy.
  • Commercial battery energy storage systems (C&I BESS): Evaluate the available space for installation, whether indoors or outdoors. It is important to consider factors such as ventilation, safety clearances, and compliance with UK electrical and fire safety regulations.
  • Hybrid inverters for new solar installations, combining solar panel output and battery storage in a single solution
  • AC-coupled inverters, ideal for retrofitting existing PV systems with string inverters
  • Solar battery packages which are designed to simplify selection and installation by bundling compatible products into one solution
  • Modular battery designs for flexible and scalable expansion
  • Full range of energy management product, including battery management systems (BMS), smart monitoring tools, smart controllers, and accessories

Why Choose Solar Battery Storage?

Benefits of installing battery storage with solar PV systems:

  • Store excess solar energy by solar panels during the day for use in the evening, during peak electricity tariff periods, or in the event of a power outage
  • Maximise self-consumption and reduce grid dependency
  • Helps reduce energy bills and overall energy costs for both residential and commercial customers, including homeowners and businesses
  • Support smart grid integration and participate in demand response schemes
  • Reduce carbon footprint while ensuring reliable power

Solar Battery Storage Solutions: Our Brands vs Alternatives

While brands like Tesla, Sigenergy, and GivEnergy are available options in the UK solar battery storage market, our trusted partners deliver greater value, flexibility, and installer-focused support across both residential and commercial energy storage projects.

How Our Solar Battery Brands Compare:

  • Huawei and Sungrow offer UK installers the best of both worlds: premium solar battery storage performance without the typical limitations of the premium market. Their systems are just as capable — and often more practical — than higher-cost competitors in real-world residential and commercial applications.
  • For installers working within the value-to-mid-tier segment, Growatt and Fox ESS offer performance that matches or exceeds alternatives like GivEnergy, SolaX, Pylontech, and Dyness, particularly considering value, flexibility, and ease of installation.
    Growatt battery storage is especially popular for residential use, known for its modular design, seamless inverter integration, and cost-effective pricing — making it a smart choice for domestic installations.
  • Dunext, like Huawei and Sungrow, competes in the commercial and industrial (C&I) battery storage market and is a rising player in the UK. Dunext delivers scalable DC-coupled battery storage for large-scale solar projects at great value.
