Large-scale inverters for three of Stella Futura’s larger sites
During the autumn, Stella Futura's engineers, in collaboration with our supplier SMA's engineering team, developed a design for the central inverters that will ensure efficient transfer of energy between the electricity grid and the total of 30 MW battery systems, that were delivered in April.

Large-scale inverters act as powerful converters, transforming direct current from the batteries into alternating current that can be distributed into the grid and vice versa.
In addition to optimising energy flow, large-scale inverters can also monitor and control the battery storage system to ensure optimal performance and long-term technical durability. By continuously monitoring parameters such as voltage, current, and temperature, large-scale inverters can both identify and avoid potential problems in real time, reducing the risk of downtime and maintenance costs.
A further important feature of large-scale inverters is their ability to balance the frequency of the power grid. The frequency of an electricity grid is an indicator of its stability and balance between the demand and supply of electricity. By quickly regulating the amount of energy fed into or out of the batteries, large-scale inverters can help stabilise the frequency, thereby ensuring reliable electricity supply.
