How to Choose the Right Inverter for Your Home in Siliguri

An inverter is one of those purchases most families make once in seven or eight years, so it is worth spending an hour getting it right. The three questions that decide everything are simple: what do you want running during a cut, for how long, and how sensitive are those appliances to the quality of power.

Step 1: List what must stay on

Walk through your home and note the appliances you genuinely need during an outage. In most Siliguri households that is lights, ceiling fans, a television, the Wi-Fi router and phone charging. A refrigerator and a water pump are the usual additions, and both change the sizing considerably because of their starting surge.

• LED light — about 10 watts each
• Ceiling fan — 70 to 80 watts each
• Television — 80 to 120 watts
• Wi-Fi router and set-top box — around 30 watts together
• Refrigerator — 150 to 250 watts running, with a higher start-up surge

Step 2: Convert your load into inverter VA

Add your wattage, then divide by roughly 0.8 to get the VA rating you need. A 400 watt load points to about a 500 VA inverter; add a fridge and you are closer to 900 VA. Leaving 20 to 30 percent headroom is sensible — it covers the appliance you add next year and keeps the inverter from running at its limit through a long summer evening.

Step 3: Sine wave or square wave?

Pure sine wave inverters produce power similar to the grid supply. They run televisions, refrigerators, computers and modern LED lighting quietly and without stress on the electronics. Modified or square wave units cost less but can cause humming in fans, flicker in some lights and extra heat in sensitive equipment. For a home with any modern appliances, pure sine wave is the sensible default.

Step 4: Think about Siliguri conditions

Local outages tend to cluster around monsoon storms and peak summer load, and they can last from a few minutes to several hours. Humidity also matters: an inverter mounted in a damp, unventilated corner ages faster. Choose a spot with airflow, away from direct rain spray, and keep the battery on a stand rather than a wet floor.

Step 5: Buy where service is local

An inverter is a serviceable machine, not a sealed box. Fuses blow, charging boards fail, and batteries need periodic checks. Buying from a shop in Siliguri means someone can be at your home the same day rather than a courier claim taking weeks.
