Explore Battery Storage Solutions
Our battery storage range is designed to help professional installers select compatible systems for new solar PV installations, retrofit projects, and scalable commercial energy storage applications.
Available solutions include:
Residential battery storage systems
Residential battery storage helps homeowners store excess solar energy generated during the day for use in the evening, during peak tariff periods, or when solar generation is low. Understanding the customer’s typical energy consumption and peak demand helps determine the right battery size and discharge strategy.
Commercial battery energy storage systems, or C&I BESS
Commercial and industrial battery storage systems are designed for larger energy users, businesses, and sites requiring higher-capacity energy storage. When specifying a C&I BESS solution, installers should consider available installation space, indoor or outdoor placement, ventilation, safety clearances, and compliance with UK electrical and fire safety regulations.
Hybrid inverters for new solar installations
Hybrid inverters combine solar PV generation and battery storage in one system, making them suitable for new solar installations where battery storage is planned from the start.
AC-coupled inverters for retrofit projects
AC-coupled inverters are ideal for adding battery storage to existing solar PV systems, especially where a string inverter is already installed.
Solar battery bundles and packages
Battery storage packages simplify product selection by grouping compatible batteries, inverters, BMS equipment, monitoring tools, controllers, and accessories into one solution.
Modular battery storage systems
Modular battery designs allow flexible expansion over time, helping installers specify systems that can scale with future energy demand.
Why Choose Solar Battery Storage?
Solar battery storage helps residential and commercial customers make better use of the electricity generated by their solar PV systems.
Key benefits include:
Store excess solar energy
Battery storage allows customers to store solar energy generated during the day and use it later in the evening, during peak electricity tariff periods, or during a power outage.
Increase self-consumption
A well-sized solar battery system helps customers use more of their own solar power instead of exporting excess electricity to the grid.
Reduce energy costs
Battery storage can help reduce electricity bills and overall energy costs for homeowners, businesses, and commercial sites.
Support smart energy management
Battery systems can support smart monitoring, energy management, and demand response strategies, depending on the system design and product compatibility.
Lower carbon impact
By storing and using more solar-generated electricity, customers can reduce reliance on grid electricity and support lower-carbon energy use.
