Lithium Ion Battery Technology Solutions
Features & Benefits
- Integrated electronics for battery cell monitoring & protection
- Plug and Play connection to easily install and safely remove module from the string
- Safety features include protection against rapid discharge and current limitation
- Configurable for energy systems from 24 VDC to 600 VDC
Each module contains an internal battery management system to monitor and protect the battery cells
Solar Shelters & Hybrid Power with Li-Ion
ETI’s innovative Lithium-Ion Battery modules integrate with our solar, wind, fuel cell & engine generator technologies, and are compatible with our robust power conditioning, power distribution, energy storage/backup and intelligent power managment products. By engineering each of these technologies as modular interacting systems, ETI can create hybrid power systems that are both configurable and scalable for specific needs while minimizing fuel requirements.
