It is well known that adding battery storage to a solar system minimizes the reliance on the national grid, reducing your energy bills and increases your use of green energy. VARTA Storage GmbH will upgrade their pulse energy storage systems with “Energy Manager” grid charging capabilities. This new feature will allow the homeowner not only to store the surplus electricity from the solar system during the day and use it when the energy costs are high, but also to charge the storage system during the night, when the energy is available at the lowest tariffs (off peak). As a result grid charging can improve the total economics of an energy storage system substantially.
Benefits at a glance
During the selected month, the storage system will charge during the off peak period to the configured State of Charge (SOC) with the selected charging power. When full charge is reached the storage system will change into deep sleep mode. After the off peak period the storage system changes back into standard operation mode to optimize your self-consumption. Now the low cost energy can be used during the peak period of the day. If a solar system is connected and the self-produced energy isn’t needed immediately, this will also be stored in the storage system.
Energy Manager Settings
In our example, the off-peak period is from 10 pm to 6 am. In this time the energy storage system is charged with low cost electricity. Between 6 am and 10 pm, when the electricity costs are typically higher, the storage system will provide the stored energy, allowing the use of off-peak electricity during peak times.
Grid charging will be available for pulse systems in the UK and Australia, as well as a free retrofit solution for existing pulse energy storage systems by remote software update of VARTA Technical Service.
