Tired of heavy batteries that need constant maintenance? The Invertek Li+ Series is a wall-mounted lithium ion UPS that combines the inverter and LiFePO4 battery into one slim, powerful unit.
No acid. No water. No servicing. Just pure, reliable lithium ion backup power. 3500 plus charge cycles. 10-year battery life. Zero maintenance. Available from 1050VA to 3150VA. ISO 9001:2015 certified. Made in India. 36-month direct warranty.
Old lead-acid inverter batteries are heavy, messy, and unreliable.
They need water top-ups every month.
They corrode. They lose capacity within 2 to 3 years.
They take up floor space and release harmful fumes.
There is a much better way now.
The Invertek Li+ is a complete lithium UPS system that fits neatly on your wall like a split AC unit.
It is compact, clean, and completely maintenance-free.
Why choose a lithium UPS over a traditional inverter battery?
Here is what makes the difference.
A lithium ion UPS battery backup lasts 3500 plus charge cycles compared to just 400 to 500 cycles from a standard lead-acid battery.
That means your lithium UPS battery backup lasts up to 8 to 10 years without replacement.
No water. No acid. No corrosion. No monthly maintenance visits.
The lithium ion UPS battery backup charges 3 times faster than a standard battery.
It delivers consistent power output right until the battery is fully discharged.
No dimming lights. No fan slowdowns. Just steady, reliable power throughout the outage.
The Li+ series works at voltages as low as 70V.
Even during weak grid supply or brownouts, your home stays fully powered.
Every unit delivers clean pure sine wave output that is completely safe for sensitive appliances like laptops, LED TVs, and modern refrigerators.
Lithium UPS maintenance tips are simple because there are almost none.
Just mount it on the wall, connect it, and forget it.
No periodic checks. No electrolyte refills. No terminal cleaning.
Our BMS technology handles battery protection, charge monitoring, and health management automatically.
ISO 9001:2015 certified. BIS approved. 100 percent factory tested before dispatch.
36-month direct manufacturer warranty.
100 plus authorised service partners across India.
24 to 48 hour service resolution guaranteed.
