1. Warranty Duration
- Standard Warranties: Often, the standard warranty is two years for both performance and product defects. However, extended warranties may be available, typically ranging from 5 to 10 years or more, depending on the manufacturer and specific conditions.
- Extended Warranties: These can be purchased to cover longer periods, especially in projects requiring long-term reliability assurance.
2. Performance Metrics
- Warranties often cover specific performance metrics such as:
- Capacity: Ensures the system retains a minimum percentage of its initial capacity over time.
- Energy or Power Output: Guarantees the system can deliver a certain amount of energy or power.
- Availability and Efficiency: Covers how often the system is operational and its efficiency in converting energy.
3. Conditions for Warranty
- Operating Conditions: Maintaining the system within specified temperature and state of charge ranges is crucial. Failure to adhere to these conditions can void the warranty.
- Data Logging: Regular data logging (often at intervals like 15 minutes) is required to support warranty claims, typically stored in cloud services for easy access and reporting.
- Maintenance: Regular maintenance is necessary to ensure the system operates as intended, with some manufacturers requiring connection to cloud services for firmware updates to maintain warranty validity.
4. Repair and Response Times
- Manufacturers often specify response and repair times, which can range from 24 hours to several days for response and up to a month for repairs. Liquidated damages may be applied for delays beyond these times.
5. Warranty Scope
- Basic vs. Advanced Warranties: Some manufacturers offer tiered warranties, with basic coverage for essential components and advanced coverage that extends service terms under specific conditions (like cloud connectivity).
6. Liability and Limitations
- Manufacturers generally limit liability to repair or replace defective parts, excluding indirect or consequential damages such as lost profits or goodwill.
Understanding these terms is crucial for project owners and operators to ensure they are adequately protected against potential system failures and financial risks.
