How it works

Store It. Manage It. Use It When It Counts.

1

Store

Your ESS charges from solar panels, the grid, a generator or wind, whichever power sources your site has.

2

Manage

Our built-in Energy Management System decides when to store and when to supply, automatically.

3

Use

Stored energy powers your site when you need it, and takes over within 10 milliseconds if the grid goes down.

Works with any power source, and can run your site fully off-grid:
