The 20KVA UPS price in India typically ranges from ₹1,00,000 to ₹1,50,000+ depending on technology, battery backup duration, phase configuration, and brand. For smaller setups, a complete online UPS 1KVA system starts from ₹15,000, while mid-range 6–10 KVA configurations cost ₹40,000 to ₹50,000. Lento Industries Private Limited offers the complete Zector and Vector series — covering 1KVA to 20KVA — with double conversion online UPS technology, 0ms transfer time, and a proven 2 to 3-year warranty across all models.

Why UPS Capacity Matters: From 1KVA to 20KVA

Choosing the right UPS capacity is the single most important buying decision. Too small and your system shuts down under load; too large and you overpay for idle capacity. Here's how capacity maps to real-world applications:

Capacity	Best For	Price Range
1–3 KVA	Home office, workstation, clinic, small office	₹15,000 – ₹30,000+
6–10 KVA	Server rooms, telecom racks, hospitals, banks	₹40,000 – ₹50,000+
10–20 KVA	Data centres, industrial automation, enterprise	₹1,00,000 – ₹1,50,000+

A home UPS system typically sits in the 1–3 KVA bracket, while the 20KVA range serves mission-critical commercial and industrial infrastructure.

Double Conversion Online UPS: The Technology That Matters

All Lento Zector and Vector series models use double conversion online UPS architecture — the gold standard in power protection. Unlike offline alternatives, double conversion means:

• Your load always runs on inverter-generated power — never raw grid supply
• 0ms transfer time during power failure — zero interruption, zero data loss
• Continuous voltage and frequency regulation regardless of grid quality
• Complete harmonic filtering and galvanic isolation from the mains

The contrast between online UPS and offline UPS is stark: an offline UPS reacts to failure with a 4–20ms gap — acceptable for basic home computers, catastrophic for servers, medical equipment, or industrial automation. Every Lento UPS eliminates this risk entirely.
