Frequently asked questions
What people actually ask.
Answered efficiently.
Our systems primarily use Lithium Iron Phosphate (LFP) chemistry, known for its superior thermal stability, long cycle life, and enhanced safety profile compared to other lithium-ion chemistries.
Our modular architecture allows seamless scaling from 5 kWh residential units to multi-MWh grid-scale installations. Each module can be combined in parallel to meet exact capacity requirements.
Every unit includes a multi-layer Battery Management System (BMS), thermal runaway prevention, overcurrent protection, and real-time monitoring with automatic shutdown capabilities.
