Electric Kettle	❌ No Exceeds continuous power limits.
Clothing Iron	❌ No High power draw.
Electric Geyser / Water Heater	❌ No Requires a much larger, dedicated system.

Quick Checklist Before Buying an Appliance

Find the appliance's running watts and starting watts (if it has a motor).
Sum the loads you'll run at the same time and keep the total below 2.8 kW.
Check your inverter's surge rating for fridges, pumps, or AC units.
Plan to run heavy loads during peak sun hours.

Important Note

If you need to run high-power items like an electric stove, geyser, or large air conditioner, you will need a larger system. Plan for a 5kVA inverter (or bigger), more solar panels, and a significant battery bank for reliable performance.
