The new Battery Installation Standard (code-named MIS 3012) is designed to better equip the industry to roll out battery storage installations while ensuring consumer protection. It outlines requirements for MCS certified installers who supply, design, and install electrical energy storage or battery systems. It covers installations up to 50kW and Electrical Energy Storage Systems (EESS) classes 1 – 4.
MCS piloted the scheme at the beginning of 2020 with volunteer installers, in preparation for certification bodies to begin accepting applications for certification.
Battery storage systems come in numerous forms, so for the purpose of this new standard MCS has adopted a classification system aligned with the four EESS classes:
MCS developed MIS 3012 with input from industry-leading bodies, including Tesla, Sonnen, Moixa, Powervault, AceOn Group, Solar Energy UK, and REA.
Chris Roberts, Technical Director at MCS, led the project to deliver this standard in collaboration with the MCS working group and support from Graham Kenyon, Technical Author, and Principal Consultant at G Kenyon Technology Ltd.
Roberts commented: “This is a huge milestone for MCS as we publish what we believe to be the first standard suitable for the certification of complete battery storage installations. By doing so, we aim to protect customers who invest in this pioneering technology. We also want to help the industry to grow by defining what constitutes good practice in the sale, design and installation of these systems.”
Ian Rippin, Chief Executive of MCS, added: “As we continue to support the sector and its continued innovation, our battery storage standard will be backed by scheme requirements managed independently and impartially.
“For installers, this represents a one-stop-shop for all their registrations without the need to access a different system. This is also about enabling the industry to deliver the best outcomes for the consumers it serves – the ability to search for all their renewable energy needs, including battery storage solutions, in one place.”
Registrations under MIS 3012 will sit alongside existing small-scale renewable energy installations that are currently held centrally within the MCS Installation Database. This includes MCS certification of other microgeneration technologies used to produce electricity and heat from low carbon sources, such as solar PV, heat pumps and biomass.
MCS will be running an introductory offer for installers. Those who add battery storage to their offering or become newly certified for battery storage on or before 31 December 2022, will have 20 credits, worth £600, added to their MID (MCS Installations Database) account.
MCS is a quality assurance scheme, supported by the Department for Business, Energy & Industrial Strategy (BEIS). It provides the framework for the certification of microgeneration technologies used to produce electricity and heat from low carbon sources.
