All battery cells are protected by a best-in-class battery management system (BMS) and battery protection
unit (BPU). The BMS is responsible for monitoring, protection, and diagnostics of battery cells. Battery cells
and power conditioning units are thermally managed by a heat plate which is located on the back of
the inverter.
There are three entry ports on the XOLTA Compact BESS (Figure 3.2):
• Power entry port for electrical connection
• Ethernet port for access to internet cable
• Current Transformers (CTs) signals (modbus)
Unused port hole(s) MUST be sealed off, when installation is complete
