Conclusion First

For overseas customers, when evaluating energy storage systems, their priority concerns extend beyond mere performance metrics. Instead, they focus on system reliability, life-cycle economic viability, regulatory compliance, post-installation maintainability, and service support. These factors directly determine whether the project can operate stably as expected and continuously generate value over the years.

I. Reliability: A Core Concern

Common Questions from Overseas Customers:

• “Can the system operate stably under extreme environmental conditions (high temperature/high humidity/low temperature)?”
• “What is the failure downtime rate? What is the Mean Time Between Failures (MTBF)?”

Engineering Perspective:
Reliability is not a single parameter but a system-level indicator, encompassing:

• Thermal stability of the Power Conversion System (PCS) and battery modules.
• Coordinated control strategies between the Battery Management System (BMS) and Energy Management System (EMS).
• Thermal design, overload protection, and redundancy mechanisms.
• On-site/remote monitoring and early warning capabilities.
  Highly reliable systems often employ excellent thermal design, module redundancy, and automatic fault isolation mechanisms, significantly extending continuous operation time.

II. Life-Cycle Economic Viability (LCOE + Payback Period)

Concerns from Overseas Customers:

• How long will it take for the project to break even?
• What is the total life-cycle cost?

Core Engineering Considerations:

• Stability of peak-valley arbitrage and peak-shaving response revenues.
• System efficiency (including PCS, BMS, and thermal dissipation losses).
• Impact of battery degradation on annual available capacity.
  The life-cycle economic model often relies on:
  LCOE = (Capital Expenditure (CAPEX) + ∑ Operational Expenditure (OPEX)) / ∑ (Annual Available Electricity × Electricity Price Differential Revenue)
  The engineering optimization goal is to reduce LCOE and enhance capital return per unit.

III. Regulatory and Certification Compliance

Requirements in Overseas Markets:

• IEC/UL safety standards.
• EMC/protection class requirements.
• Grid interconnection codes and grid support requirements.
  Overseas customers are not just purchasing equipment but seeking a comprehensive system solution that is compliant, grid-interconnectable, and safe.

IV. Post-Installation Maintenance and Service Support

Key Concerns:

• Guarantee of spare parts supply.
• Response time for remote/on-site services.
• System monitoring platform and early warning mechanisms.
  After equipment deployment, a good service system can significantly reduce downtime losses and maintenance costs.

V. Engineering-Based Decision-Making Logic Summary

Overseas customers prioritize evaluating energy storage systems based on:

• Can it operate stably under extreme environmental conditions?
• Is the total life-cycle cost minimized, and the payback period controlled?
• Does it comply with local regulations and safety standards?
• Is maintenance guaranteed, and service response prompt?
