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

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
