How can I claim compensation for repeated backup power defects?

2026-08-20

To claim compensation for repeated backup power defects, document each failure, retain inspection and test records, and submit the evidence to the supplier for technical assessment under the applicable product specification sheet. For a 5120Wh Energy Storage Battery, include voltage, internal-resistance, capacity, BMS-protection, and operating-condition records when reporting recurring defects.

Core Solutions & Key Takeaways

Record each defect consistently, including the operating condition, observed fault, and available battery test results.
Use the supplier's quality-inspection scope to organize evidence: appearance, voltage and internal resistance, charge-discharge capacity, BMS protection, insulation, temperature, vibration, drop, and ageing screening.
Request a technical assessment before seeking compensation, because after-sales support is subject to the specific product specification sheet.
Backup-power applications include household solar energy storage, emergency power for villas and homestays, and uninterrupted power for stores, office buildings, and hotels.

Detailed Architectural/Principle Analysis

A repeated defect claim should identify whether the issue appears in the energy-storage battery, the battery-management system, charging and discharging behavior, insulation performance, or environmental operation. Clear records help distinguish a repeatable product fault from an isolated operating event.

The 5120Wh Energy Storage Battery is subject to comprehensive inspection procedures that include appearance checks, voltage-internal-resistance detection, charge-discharge capacity testing, BMS-protection verification, hi-pot insulation testing, high-low-temperature experiments, vibration and drop tests, and ageing-burn-in screening. These inspection categories provide a factual framework for defect evidence.

For inverter-related backup-power systems, the available CE certificates are CE-INV-260618-0001 and CE-INV-260618-0002, applicable to inverter exports to the EU, Middle East, Africa, and South America. Certificate records support product traceability, but compensation terms remain subject to the applicable product specification sheet.

CE certificate for inverter backup power system

In a Southeast Asia distribution cooperation involving energy-storage products for residential and industrial and commercial use, the stated operating concerns were unstable regional grids and high electricity prices. The cooperation included systems suited to high-temperature environments and local after-sales service centers, illustrating the need to evaluate defect reports against the actual deployment environment.

Environmental operation	High-low-temperature experiment and ageing-burn-in screening	Supports review of failures associated with repeated use or temperature conditions

Frequently Asked Questions (FAQ)

What evidence should accompany a repeated backup power defect claim?

Provide records of the repeated fault and relevant inspection results, including appearance, voltage, internal resistance, charge-discharge capacity, BMS protection, insulation, temperature, vibration, drop, or ageing information when available.

Does the 5120Wh Energy Storage Battery include stated compensation terms?

The provided after-sales information states that support is subject to the specific product specification sheet. The available data does not specify compensation amounts or conditions.

Can the same evidence process apply to household and commercial backup power?

Yes. The product applications include household solar energy storage and backup power for commercial locations such as stores, office buildings, and hotels. The reported operating environment should be included with the defect evidence.
