Luminous — Persistent failure of luminous solar inverter system

Subject: Strong Complaint Regarding Persistent Failure of Luminous Solar Inverter System

Dear Luminous Customer Support,

I am writing to lodge a strong complaint regarding my Luminous solar power system, which has remained unresolved despite repeated service visits and multiple repairs over the last two months.

The issues are as follows:

* Every morning, the inverter has to be switched OFF and ON manually.
* Whenever there is a power cut during the day, the entire solar system shuts down and remains OFF.
* This happens regularly, especially between 10:30 AM–4:00 PM and 4:00 PM–7:00 PM.
* Each time, we have to manually press the push button to restart the system.
* A local technician made several attempts to fix the problem but could not resolve it.

The service history is extremely concerning:

1. The Luminous service engineer replaced the PCB/card five times.
2. Even after multiple PCB replacements, the inverter never charged from the solar panels.
3. It continued to charge only from the grid supply.
4. This issue has persisted for the last two months.
5. We were instructed to improve the earthing, which we completed, but there was no improvement.
6. The engineer even took the inverter for inspection/testing.
7. Despite all these efforts, the problem remained unresolved.
8. Only after the final PCB/card replacement did the system start functioning.
9. This strongly indicates that the previously installed PCBs/cards were faulty or not properly tested before installation.

I request Luminous to explain:

* Why were multiple faulty PCBs installed one after another?
* Why was the issue allowed to continue for two months despite repeated service visits?
* Why was unnecessary time, effort, and inconvenience caused to the customer?

This has resulted in significant inconvenience, repeated service visits, loss of confidence in the product, and disruption to the performance of the solar system.

I request a thorough investigation, a written explanation, and a permanent resolution. I also expect appropriate action to ensure that such negligence is not repeated with any customer.

Please treat this matter as urgent and respond at the earliest.
