If your Luminous inverter or home UPS has stopped charging, isn’t switching over during a power cut, or is showing a fault, you can register a complaint directly with Luminous online — no need to visit a store. Here’s the exact process, using Luminous’s official support channels.
Step 1: Check If Your Product Is Registered
Luminous recommends registering your product after purchase, which speeds up any future complaint significantly since your details and warranty status are already on file. If you haven’t registered yours yet, do it first at Luminous’s official “Register your product” page (linked from luminousindia.com/support) — it takes a few minutes and needs your invoice details and serial number.
If you skipped this step, don’t worry — you can still register a complaint using your invoice as proof of purchase.
Step 2: Gather What You’ll Need Before Registering
- Invoice/proof of purchase, with date
- Model name and serial number (printed on a sticker on the unit itself)
- A brief, clear description of the issue (e.g., “not charging after power cut,” “backup fuse blows on restore,” “battery shows low even after full charge”)
- Photos of the unit/fault if relevant
Step 3: Register Your Complaint Online
Luminous offers a dedicated online complaint form. Go to:
luminousindia.com → Support → Book a Complaint
Fill in your product details, describe the issue, and submit. You should receive a complaint/ticket number — save this, as it’s your reference for all future follow-ups.
Step 4: Alternative Ways to Register a Complaint
If you prefer not to use the online form, or want to register through another channel:
- Toll-free number: 1800-103-3039 (9:00 AM – 6:00 PM)
- Phone: +91-7042833939
- Email: care@luminousindia.com — attach your invoice and describe the issue clearly, this also creates a written record automatically
Step 5: What Happens After You Register
Once your complaint is logged, a service technician is typically assigned to visit and inspect the unit, especially for inverter/UPS units that aren’t easily portable. Make sure someone is available at the registered address during the technician’s visit window, and keep your ticket number handy — it’s the first thing they’ll ask for.
Realistic Timelines
Straightforward issues (a blown fuse, a loose connection) are often resolved within a few days of the technician visit. More involved repairs — like PCB replacement or battery diagnosis — can take 1–2 weeks depending on parts availability and your service center’s workload. If you’re well past this without any update, that’s your cue to follow up actively rather than wait.
If Your Complaint Isn’t Being Addressed
Unfortunately, non-responsiveness is a genuine, recurring complaint pattern people report with several appliance and inverter brands. If your complaint has gone unanswered:
- Follow up by email (care@luminousindia.com), referencing your ticket number and complaint date directly — this is more effective than repeated calls, since it’s documented
- Ask explicitly to escalate to a senior support representative or service manager when you call
- If there’s still no resolution after a reasonable window (1–2 weeks past the promised timeline), you can:
- File with the National Consumer Helpline — call 1915, use the UMANG app, or go to consumerhelpline.gov.in. This is a free government mediation service and tends to get faster movement than individual follow-ups, since it’s tracked against the company.
- If the issue remains unresolved or involves a significant cost, file a formal complaint with your local Consumer Disputes Redressal Commission via the e-daakhil portal (e-daakhil.nic.in) — no lawyer needed to file.
A Practical Tip
If your inverter is under warranty and a technician tries to charge you for a repair you believe should be covered, ask for the warranty status to be confirmed against your registered product/serial number before agreeing to pay — this avoids disputes over charges after the fact.
FAQs
Q: Is there a cost to register a complaint? No, registering a complaint through Luminous’s official channels — online form, phone, or email — is free. You may be charged separately only for repairs or parts not covered under warranty.
Q: Can I track my complaint status online? Check the Luminous support page for a complaint tracking option using your ticket number; if unavailable online, you can also get a status update by calling the toll-free number and quoting your ticket.
Q: What if I don’t have my invoice anymore? If you registered your product after purchase, Luminous should have your purchase details on file. Otherwise, check your email for an order confirmation, or your retailer/dealer for a duplicate invoice.
Q: Does registering a complaint affect my warranty period? No, raising a complaint doesn’t extend or shorten your warranty — the original warranty period is based on your purchase/invoice date regardless of how many complaints are raised during that window.
