Technology
Sierra is the world’s first fully bidirectional power converter.
The three ports (two AC and one DC) built into each module can all function as input and output.
This means that you can use it to secure AC & DC loads and charge batteries at the same time.
Sierra is also the right choice for energy management applications such as peak shavings, phasebalancing or innovative solutions based on energy sharing via a DC distribution.

How it works?
At the heart of each module, there is a DC energy buffer. It uses the energy that comes, whatever its source, to feed what needs it. The total output
power is shared live between the loads and the batteries. It’s that simple! No configuration is required, you are totally autonomous.
