FAQ
Q:
What is the system efficiency and lifespan?
A.Round-trip efficiency: >89% (AC-coupled), >93% (DC-coupled). Cycle life: 8,000 cycles at 80% DoD (10-year design life). Warranty: 5 years (or 3,000 cycles) for batteries; 2 years for PCS/PDU.
Q:
What fire protection measures are implemented?
A.Dual-layer aerosol suppression: Pack-level: 144g units (185°C thermal trigger, ≤12s response). Container-level: 300g electric-start units (smoke/temperature detection). Five-in-one sensors: H₂/CO/temperature/smoke/flame detection.
Q:
How does the thermal management system ensure safety?
A.Liquid cooling (50% glycol solution) maintains cell ΔT <3°C. Operating range: -30°C to +55°C (discharge), 0°C to +60°C (charge). Redundancy: Dual pumps + fail-safe controls.
Q:
What certifications do SolarEast’s cabinets comply with?
A.All products meet: Safety: IEC 62619, UL 1973 (battery), UL 9540A (fire). Grid compliance: CE, UKCA, IEEE 1547 for grid interconnection. Transport: UN38.3 for lithium batteries.
Q:
What is the system composition of SolarEast’s C&I ESS?
A.Battery clusters (LiFePO₄ cells, liquid-cooled packs). Power conversion: PCS (AC-coupled) or high-voltage PDU (DC-coupled). Safety systems: Aerosol fire suppression (Pack/Container-level), IP54-rated enclosures. Smart controls: Tiered BMS (BMU/BCU/BAU), EMS for energy scheduling.
Q:
What are the key product lines in SolarEast BESS’s C&I ESS portfolio?
A.What are the key product lines in SolarEast BESS’s C&I ESS portfolio? 100kWh/125kWh/215kWh/241kWh/261kWh/418kWh AC-coupled cabinets: Integrated with PCS for grid-tied applications (e.g., peak shaving, PV self-consumption). 418kWh DC-coupled systems: Designed for large-scale DC integration (e.g., solar-plus-storage plants). *Note: 100-215kWh uses 280Ah cells; 241kWh/261kWh/418kWh use 314Ah cells for higher energy density.*
Q:
Can the BESS system be customized?
A.Yes. SolarEast BESS provides OEM/ODM solutions to meet specific capacity, voltage, and integration requirements for different business needs.
Q:
How long does it take to install the system?
A.Thanks to its all-in-one cabinet design, installation is fast and straightforward, reducing onsite labor and deployment time significantly.
Q:
What safety features are included?
A.The system includes a comprehensive fire protection system with: Smoke and temperature detectors Electric aerosol fire extinguishing Real-time signal integration with a fire control host and alarm system Ensuring multi-level safety in every operating condition.
