VA Sizing for Indian Homes
850VA handles: 3 fans + 4 lights + TV + router (~400–500W). 1100VA handles: 4 fans + 6 lights + TV + fridge on backup (~600–700W). 2KVA handles: AC + fridge + all fans + lights. Rule: add up watt ratings of all devices you want backed up, multiply by 1.2 for safety margin = minimum VA required.
Li-ion vs Lead Acid Battery — 2026
Lead-acid (100–200Ah): cheaper upfront (₹8,000–12,000), needs distilled water monthly, produces acid fumes, lasts 3–4 years. Li-ion (Genus MaxiLion, Microtek): ₹20,000–25,000 more upfront, zero maintenance, no fumes (safe for flats), lasts 10+ years. Over 10 years, Li-ion is actually cheaper. For flats: Li-ion is the 2026 recommended choice.
Pure Sine Wave vs Square Wave
All 5 inverters in this list are Pure Sine Wave — the only correct choice for 2026. Square wave inverters damage refrigerators, ACs, washing machines, and modern electronics. Pure Sine Wave (like grid power) is 100% safe for all appliances. Never buy a square wave inverter for an Indian home.
How to Calculate Backup Hours
Formula: Backup hours = (Battery Ah × 12V × 0.8 efficiency) ÷ Total Load Watts. Example: 150Ah × 12 × 0.8 ÷ 400W = 3.6 hours. A 200Ah battery at 400W load = 4.8 hours. Same 200Ah at 200W load (night — fewer devices) = 9.6 hours. Real backup depends on actual wattage of running devices.
Battery Maintenance for Indian Climate
Indian summers (40–48°C) are brutal on batteries. Always: keep battery in ventilated area (not enclosed cabinet), check distilled water level every 45 days in summer vs 60 days in winter, clean terminals with baking soda + water monthly. Li-ion batteries require zero maintenance in any climate — a major advantage for North Indian heat zones.
Installation & Inverter Placement
Lead-acid batteries emit hydrogen gas during charging — never install in enclosed rooms or near flames. Use a ventilated utility room, balcony, or under-staircase area. Li-ion inverters (Genus MaxiLion, Microtek wall-mount) can be placed in any room — living room, bedroom — because they produce zero fumes. Always get installation done by certified electrician — wrong wiring causes fires.
