WARNING:
The XOLTA outdoor BESS should not be installed at the following locations:
• Areas prone to earthquakes
• Altitudes above 2000 meters above sea level; up to 4000 meters might be permissible but
will require converter’s maximum power derating
• Areas prone to flooding, open flames, explosion and extreme changes of ambient temperature
3.3 Installation procedure
3.3.1 Electrical requirements
The XOLTA outdoor BESS has been designed for connection to low voltage three phase
400V AC 50Hz electrical grids. However, the system can also be connected to grids with other
voltage levels (e.g. medium voltage level) if appropriate power/voltage conditioning units such
as power transformers are in place. Each XOLTA outdoor BESS cabinet (rack) has the following
electrical requirements:
• 3 P+PE 400V AC 50Hz connection point;
• 1 P+N+PE 230V AC 50Hz connection.
Electrical installations and protection circuits must only be undertaken by an authorized electrician.
Figure 3.2 shows the installation and protection schematics for the 30kVA battery rack.
