High Voltage LFP Battery Rack – 176S280
Grade A LFP(lithium iron phosphate) cells to ensure safety and performance
LFP (lithium iron phosphate) cell to ensure the highest safety
Product Details
Watt Low Voltage Residential Energy Storage System – Compact Series
This high-voltage lithium iron phosphate (LFP) battery rack is designed for large residential, commercial, and industrial energy storage systems where reliability, safety, and scalability are critical. Built with advanced LFP cells, it delivers long service life, stable performance, and high energy efficiency even under demanding operating conditions.
With a modular rack-based architecture, the system allows flexible expansion to meet growing energy needs. It supports optimal self-consumption of solar energy, reduces dependence on the public grid, and helps lower overall energy costs. The integrated battery management system (BMS) continuously monitors voltage, current, temperature, and state of charge to ensure safe and balanced operation.
Engineered for high efficiency and long endurance, this solution is ideal for hybrid solar systems, backup power applications, and grid-connected energy storage projects. Its robust cabinet design, wide operating temperature range, and high cycle life make it suitable for long-term deployment in both indoor and controlled outdoor environments.
