XOLTA Compact
BESS entry ports.
The battery is equipped with a site controller. The site controller is the ’brain’ of the BESS and is responsible
for battery system energy management and communication with the various system components. It also
provides Internet connectivity for the XOLTA cloud.
3.3 Software description
The system control logic and data analysis are shared by our site controller and the Cloud. The site controller
takes care of all the fast response requests from the grid. It can ensure that the system operates safely
without the internet connection and collects moderate amount of data as back up. As shown in Figure 3.3,
the Cloud is a bigger playground for all the data to drop in and to be processed for supporting further analytical
functions, such as monitoring, alert, economic summary, forecasting, advanced control algorithm, etc.

The communication between the site controller and the Cloud is through a secured https connection.
This ensures the cyber security of the XOLTA system.
