Frequently Asked Questions
Have questions about our racking system? Some of these might help.
What applications is this energy storage system designed for?
Our BESS supports grid-tied, off-grid, and hybrid applications, making it ideal for solar + storage, peak shaving, backup power, and microgrids. The system features advanced thermal management designed to ensure stable, efficient operation across a wide range of environmental conditions.
Why is liquid cooling a key advantage of this BESS?
Liquid cooling maintains extremely stable cell temperatures, with differences of less than 3 °C across the battery packs. This extends battery lifespan, improves efficiency, and ensures reliable performance even in high-temperature environments.
How safe is the system for long-term operation?
Safety is ensured through LiFePO₄ battery chemistry, an intelligent BMS, continuous monitoring, gas detection, ventilation, and integrated aerosol fire suppression. These layered protections enable secure and reliable long-term operation.
Is the system compliant with FEOC-free requirements?
Yes. The system is designed using FEOC-free materials and supply chains, supporting compliance with US regulatory and procurement requirements. This makes it suitable for projects requiring transparent, non-restricted sourcing.
Is the system suitable for outdoor and harsh environments?
Yes. The system is designed for outdoor installation with a robust enclosure, corrosion protection, and a wide operating temperature range from –30°C to +60°C. This makes it suitable for diverse climates and demanding site conditions.
