I have purchased Luminous inverter and battery in 2021. The battery gave good backup for 1 year, then after 1 year, it started giving backup for 2 to 3 hours, loan only 2 fans and 1 light then I filed a complaint, the technician checked and said that it was fine . After 2 years same condition thene replaced the battery in this year 2024 and sme issues again no backup.
Very bad services and quality.
