Frequently Asked Questions

Everything you need to know about lithium UPS systems with inbuilt batteries and BMS protection.

Lithium UPS systems use advanced lithium-ion batteries (LiFePO4) offering ≥5000 charge cycles vs ~500 for lead-acid, 3× lighter weight, no maintenance (no water topping), faster 25A charging, and longer backup per kWh. Built-in BMS prevents deep-discharge and overcharge, extending lifespan significantly.
 
Pure sine wave output matches grid power quality, ensuring safe operation of sensitive electronics (computers, medical equipment, variable-speed motors, audio systems). DSP-controlled inverters eliminate harmonic distortion, preventing overheating and equipment damage.
 
Our Li+ UPS models support up to 25A charging current (1C rate for compatible batteries), allowing rapid battery replenishment when grid power returns. For example, a 100Ah battery can charge in ~4 hours vs 10-15 hours with conventional chargers. BMS regulates charging to prevent over-current and over-voltage.
 
Every Li+ UPS includes: (1) Overload protection, (2) Short circuit protection, (3) Over-temperature shutdown, (4) Deep-discharge cut-off (BMS), (5) Over-charge prevention (BMS), (6) Over-current protection. Galvanic isolation transformer adds electrical isolation for enhanced safety.
 
Yes. All Li+ UPS models feature automatic bypass and wide input voltage range (230V ± 25%), making them compatible with diesel/petrol generators. The UPS automatically switches to bypass mode during generator operation if needed, protecting the inverter.
 
3-year comprehensive warranty covering inverter electronics and lithium battery. Free home service for installation support. Extended warranty plans available. Excludes damage from misuse, lightning, or unauthorized modifications.
 
For typical 2-3 BHK home (WiFi, TV, 4-5 lights, 2 fans, laptop): Li+ 1100/12V (compact wall mount). For larger homes or small offices (additional load like desktop PCs, printer): Li+ 2000VA or 2500/24V (floor standing). Calculate your total wattage and choose a model with 20-30% headroom.
 
Yes, we ship pan-India via Shiprocket/Delhivery. Free shipping on orders ₹20,000+. Installation guides (PDF) included. Professional installation available in metro cities (contact support for quote). Typical delivery: 3-7 business days depending on PIN code.
