EESS (Battery back up)
The installation of Electrical Energy Storage Systems (EESS) is a crucial aspect of ensuring the efficiency of buildings and facilities. This guide covers the basics of what an EESS system is and how they can help reduce the reliance of taking power from the grid and harvest energy.
Understanding EESS
EESS refers to the systems designed to store energy that is created from renewables such as Solar Panels (PV) or directly from the grid when the tariffs are lower. This stored energy can then be used in the property to power essential circuits either during peak hours or in the event of power failure. Any extra energy that is unused can also be used to charge Electric Vehicles or sold back to the grid with more companies offering incentives to prosumers.
Key Terminology of EESS Installation
-
Battery & Battery Management System
-
The battery units store the energy as DC power
-
The management system controls the batteries and can limit the amount of charge and discharge cycles
-
-
Inverter
-
Essential for and PV or EESS installation. The inverter is used to convert AC power that is used in homes to DC power for storage
-
Also used to convert DC to AC when used for PV installs or selling back to the grid
-
New generation hybrid inverters give prosumers both functions offering more control of your carbon footprint
-
-
Prosumer:
-
Used to describe a house hold that generates power within the building
-
Energy companies will use these terms when offering tariffs to supply to the grid
-
-
Essential circuits:
-
Include emergency lighting circuits, supplies to combi boilers, minimal socket circuits
-
Used to ensure power in grid outages or run through the night in island mode (Free from the grid)
-
Servicing and Maintenance
Regular servicing and maintenance are essential for the longevity and reliability of EESS. Here are some best practices:
-
Routine Inspections: Conduct regular checks of all components to identify wear and potential issues early.
-
Testing Schedules: Adhere to recommended testing intervals to detect and rectify faults promptly.
-
Component Replacement: Replace worn or faulty components immediately to maintain system integrity.
-
Documentation: Keep detailed records of all inspections, tests, and maintenance activities for future reference.
-
Compliance: All relevant electrical codes and standards will be followed to ensure the safety and legality of installations
