Siemens AG, Europe’s largest industrial manufacturing company has made its move into the battery storage system segment with the launch of its Junelight Smart Battery System recently.
With the Junelight Smart Battery, Siemens is offering its first battery storage specially geared to the requirements in private homes for the storage and use of self-generated energy. The lithium-ion storage combines functions for intelligent and safe energy management and modern design. Homeowners can use it to maximise the share of their self-generated energy, e.g. from photovoltaic systems, for their own consumption, to minimise their energy procurement costs and to make a long-term contribution towards the reduction of CO2 emissions.
The Junelight Smart Battery coordinates the predictive charging and discharging procedures depending on the weather-related yield forecast of the photovoltaic system and the individual consumption profile of the household. Using the mobile Junelight Smart App, all energy flows – from production, through storage, right down to consumption and grid in-feed – can always be monitored in real time.
The storage capacity can be flexibly adapted to individual needs at any time, encompassing up to 19.8-kilowatt hours (kWh). The Junelight Smart Battery is now available in Germany and will be launched in Austria in April 2019.
”More and more homeowners are generating their own solar power – and, in light of sinking feed-in tariffs and rising electricity prices, they want to use it completely for their own consumption wherever possible. The Junelight Smart Battery creates the technical basis for future-driven, sustainable and economical energy management within the home. This allows homeowners not only to lower their energy costs, but they are also making a substantive contribution towards the success of the energy transition,” says Andreas Matthé, CEO of the Siemens Business Unit Low Voltage & Products.
When charging and discharging the battery, the Junelight Smart Battery automatically takes user-specific weather and consumption forecasts into account. This means the battery is only completely charged in times with high photovoltaic power dissipation, thus minimizing power losses. The high quality and safety of the Junelight Smart Battery have been confirmed by the VDE Association for Electrical, Electronic and Information Technologies: both the manufacturing process and the complete system have been certified according to all relevant standards. In addition, each software update is tested by the VDE in terms of safety-relevant influences. This guarantees maximum safety for both persons and buildings.
The capacity of the Junelight Smart Battery allows for unlimited modular expansion at any time: up to six battery units with a net capacity of 3.3 kWh each can be retrofitted and flexibly adapted to changes in consumer behaviour, e.g. when connecting heat pumps or charging electric vehicles. The standard hardware of the Junelight Smart Battery is equipped with all relevant connections for future functional expansions, e.g. for new app features or functions involving intelligent consumption control. As a result, the system provides for easy successive expansion via software updates.
The Junelight Smart Battery is receiving this year IF Design Award 2019 both for the outstanding design of the hardware and the mobile Smart App.
