Battery energy storage systems with grid-connected solar photovoltaics BR 514
Battery energy storage systems with grid-connected solar photovoltaics: A technical guide (BR 514) was written by Martin Cotterell and Edited by Chris Coonick, Steve Pester and Jonny Williams. It was published by BRE on 5 September 2017.
This 36-page guide covers battery energy storage systems for domestic or small commercial grid-connected solar photovoltaics (PV). Adding energy storage to these installations is considered for two main reasons; storing surplus solar PV energy for use later in the day, and providing a back-up power supply in the event of a power cut.
The guide focuses on grid-connected solar PV systems, although some of the principles described may apply to other forms of energy generation. It does not cover systems that make use of ‘spare’ storage capability available from an electric vehicle.
The guide allows customers to assess the benefits of energy storage systems, the pros and cons of different system types and the implications of different system sizes and operating regimes, and it also allows system designers and installers to undertake safe and effective design, specification and installation.
It considers the design, sizing and specification of energy storage systems that use established battery technologies to store solar surplus for use later in the day. Typical operating patterns and characteristics are also examined, and examples are given for how systems can be configured and connected within a building, and the process for sizing batteries and other components.
The contents are:
- Battery charging.
- System components and configurations.
- System operation.
- Design and installation requirements.
- References and further reading.
