Sonex Smart Energy Tool — Version 1

Fan Energy & Electricity Cost Calculator

Estimate how many electricity units your fans may use, compare an existing fan with Sonex, and understand the currently published electrical specifications. Model-specific speed, airflow and laboratory data will be added after technical verification.

Calculate your fan running cost

Choose a Sonex technology preset or enter your own verified wattage.

Electricity rate: Rs 60/unit is only an editable example. Enter the effective rate you want to use from your bill. Taxes, fuel adjustments, slabs and fixed charges are not calculated separately.

Actual consumption varies with speed, voltage, operating conditions and exact model/variant.

Currently published Sonex data

Important: “Inverter 30 Watt” is a series name, not a promise that the fan consumes exactly 30W at every speed. The calculator uses the published range until speed-by-speed factory readings are received.

Compare your current fan

Enter your current fan’s verified wattage. The comparison uses the same fan count, daily hours and electricity rate.

What the current calculator can use

Inverter 30 Watt series56-inch; BLDC; 140–220V AC; 5–45W published consumption; 120–370 RPM; speeds 1–6; PF 0.99. AC/DC on AC supply56-inch; BLDC; 140–220V AC; 5–55W published consumption; 160–375 RPM; speeds 1–6; PF 0.99. AC/DC on DC supply12V; 120–335 RPM; listed current 3.5A. This Version 1 does not convert that figure into battery-runtime promises. 220V versionsAvailable in the Sonex catalog, but exact verified wattage is not loaded yet.

Calculation formula: Monthly units (kWh) = Watts × hours/day × days/month × number of fans ÷ 1000. Results are estimates, not guaranteed bills or savings.
