Warranty Policy
Effective date: 15 October 2026
This manufacturer’s warranty policy is issued by K.J Advanced Energies Private Limited for eligible KAEL products purchased through authorized channels. The applicable invoice, product-specific warranty card and any written product-specific terms should be kept for reference. Consumer rights under applicable law remain unaffected.
1. Warranty duration by product
| Product category | Covered component | Manufacturer warranty |
|---|---|---|
| 1100VA integrated lithium inverter | Inbuilt lithium battery | 3 years, repair-only |
| 1100VA integrated lithium inverter | Inverter electronics | 2 years, repair-only |
| 2500VA integrated lithium inverter | Inbuilt lithium battery | 3 years, repair-only |
| 2500VA integrated lithium inverter | Inverter electronics | 2 years, repair-only |
| Eligible 12V retrofit lithium batteries, including 105Ah and 150Ah variants | Battery pack | 5 years, repair-only |
The warranty period begins on the original purchase invoice date, unless the product-specific written warranty expressly states a different legally valid start date. Any charger or third-party accessory has only the warranty separately stated for that item, if applicable.
2. What the manufacturer’s warranty covers
During the applicable warranty period, we will inspect reported faults and repair covered manufacturing or material defects in the relevant product or component, subject to diagnosis and the conditions below. Repairs may involve servicing or replacement of internal parts with suitable equivalent components. A completed repair does not restart or extend the original warranty period unless required by applicable law or confirmed in writing.
3. Exclusions and limitations
This limited manufacturer warranty does not cover damage caused by improper electrical connection, reversed polarity, short circuit, incompatible charger or inverter, operation outside published limits, physical impact, fire or external flooding, unauthorized modification, deliberate tampering, or other misuse. Ordinary cosmetic wear and externally caused damage are not manufacturing defects. Normal capacity variation with age and use is not automatically a defect; a claimed performance fault will be assessed against the applicable written product specifications and operating conditions. An exclusion will be applied only where relevant to the failure being assessed and to the extent permitted by law.
4. Customer responsibilities
Use the product according to the user manual and specified limits. Preserve proof of purchase, serial number labels and relevant installation details. Do not open the enclosure, interfere with the BMS, bypass safety protection or attempt unsafe repairs. Stop using the product if it becomes unusually hot, swollen, damaged or otherwise unsafe, and contact support for instructions.
5. Making a warranty claim
- Contact KAEL with your name, phone number, purchase invoice or order number, product model, serial number and description of the problem.
- Our support team may request photographs, fault indications, usage details and basic safe troubleshooting information.
- If physical inspection is required, we will arrange or explain the service or collection process and any applicable conditions before proceeding.
- Once diagnosed, we will communicate whether the fault is covered and the proposed repair process. Charges for work outside warranty, if any, will be explained for approval.
6. Service arrangements
Service arrangements depend on location, product accessibility and the nature of the fault. Availability of on-site inspection or service should be confirmed with our team; an on-site visit is not automatically included for every product. Do not ship lithium batteries without our transport instructions.
7. Legal rights
This is a repair-only manufacturer’s warranty, not a restriction of rights that cannot be excluded under applicable Indian consumer law. Where a customer is legally entitled to another remedy, including replacement, refund or compensation, the applicable law prevails.
