The BMS-Inverter Hybrid Project combines two central components in battery storage systems – the battery management system and the inverter – into a single solution, leading to lower system costs and increased lifespan.

How the project works

The project created a single set of electronics that unifies the function of both a battery management system and a battery inverter. Connecting directly to the battery, the BMS-Inverter will ensure safe and effective operation of the battery, as well as convert the direct current (DC) power from battery cells to mains alternating current (AC) power.

This has potential to provide substantial cost and performance benefits in new and second-life battery storage systems.

Area of innovation

The BMS-Inverter Hybrid uses sophisticated electronics that can be connected to battery cells and immediately make these AC ready, without needing an inverter. This can significantly reduce the cost of storing energy across the lifetime of a battery storage system and help deliver reliable electricity at peak times by reducing the pressure on the grid.


Stationary battery storage systems offer a path towards a reliable, sustainable and affordable power supply. Battery inverters and battery management systems together represent a significant proportion of battery storage system cost. Given the need for dispatchable power to support the increasing levels of variable renewable energy on the grid from both centralised and distributed generation, the project presents a significant opportunity to increase uptake of renewables in Australia and allow a smooth shift to a higher share of renewable energy sources.
