Inverters & UPS Price Tracker

VA Rating Sizing

Calculate your total load in watts and add a 20% buffer to determine the VA rating. A 900VA inverter handles fans, lights, TV, and router comfortably for a 2BHK. For ACs or heavy appliances, step up to 2kVA or higher. Undersizing causes overload shutdowns and reduces equipment lifespan.

Waveform Types

Pure sine wave inverters are essential for sensitive electronics—laptops, refrigerators, and medical equipment. Modified sine wave units cost 30–40% less but cause motor humming and can damage modern appliances. For Indian homes with mixed loads, pure sine wave is the only practical choice today.

Battery Compatibility

Match your inverter's charging current to battery type. Flat plate batteries charge faster but last 2–3 years; tubular batteries need slower charging but deliver 4–5 years of service. Most branded inverters offer selectable battery-type modes. Never pair a low-VA inverter with an oversized battery—it prolongs charging and stresses the transformer.

Warranty & Service

Luminous, Microtek, and V-Guard offer 2-year standard warranties with pan-India service networks across 500+ cities. Check whether the warranty is on-site or carry-in. Register your product online within 15 days of purchase. Extended warranties (₹500–₹1,500) are worthwhile for inverters above ₹10,000 given high repair costs.
