Battery Module BST‑20.0LV
System with energy capacity 21.68 kWh is environmentally friendly. It contains four lithium iron phosphate battery modules and a unique battery management system.
Due to the characteristics of the batteries, charging will be derated at temperatures below 15 °C. The actual usable capacity of the system is affected by the ambient temperature, the output power of the power supply module and its efficiency.
