Luminous unveils integrated lithium battery inverter


Luminous Power Technologies has unveiled Li-ON series inverters with integrated lithium-ion battery as a compact, safe and efficient power backup solution for retail and domestic segments. The new inverters provide high rated performance with negligible maintenance compared to conventional battery-based inverters.

The integrated lithium battery promises a three times longer life than conventional batteries. Additionally, the inverter supports fast charging and can completely charge the battery with grid electricity in just four hours.

Li-ON 1250, the first in the Li-ON series, features a battery management system (BMS) that manages the performance of both the inverter and the battery, thereby increasing its performance and life. The 1,100VA inverter can run a maximum of 880W of load and is ideal for running up to a three-bedroom house or a large showroom with a backup time of more than three hours at 50% load. An advanced LCD screen displays running statistics like battery charging time and backup time.

“The product supports energy efficiency with less power required to charge the lithium-ion battery than conventional batteries. In addition, the lithium battery provides a consistent backup over its lifecycle,” Amit Shukla, senior vice president and head (Power Solutions Business), Luminous Power Technologies, told pv magazine.

Space is not a constraint with Li-ON integrated inverters. “Customer need not look for a separate space to keep this inverter as it’s quite compact, approximately 60% lesser in size than conventional battery-based solutions,” added Shukla.

The Li-ON power backup solution is safe as it eliminates the risk of accidental contact by doing away with wires and terminals. Its pure sine wave output protects connected appliances from voltage surges and short circuits.

“Overall, the product is designed to offer new-age features which add value to the lives of the consumer. Three times longer battery life, three times faster charging, consistent backup time, maintenance-free and five-years warranty are real differentiators and drivers for any consumer to buy this product,” as per the company.

Loads supported by the 1100VA model include lighting, TV sets, refrigerators, audio systems, fans, and computers but not air-conditioners and microwave ovens.

“The electronics part, including the battery management system, is in-house designed and manufactured by Luminous. So, we are only outsourcing the battery component. Moving forward, we plan to start assembling batteries too in-house only,” said Shukla.

Luminous plans to launch more products in this particular segment with this technology by the end of this year. It is also working on other lithium technology products that are ready to connect to solar power too.

Luminous’ Li-ON integrated inverter is priced at approximately INR 50,000 and will initially be available across Metro and Tier-1 locations in India. The company plans to leverage its existing sales network of more than 35,000 distributors and dealers to reach households across the country.
