1. 1 TATA STEEL TECHNICAL INSTITUTE SHOPTALK PRESENTATION ON DIFFERENCE BETWEEN GENERATOR & INVERTER TATA STEEL TECHNICAL INSTITUTE, NEAR DURGA PUJA MAIDAAN, BURMAMINES, JAMSHEDPUR- 831007 SUBODH HANSDA TOKEN NO. : BNTC2324044 SECTION : E2

2. 2 TATA STEEL TECHNICAL INSTITUTE, NEAR DURGA PUJA MAIDAAN, BURMAMINES, JAMSHEDPUR- 831007 INTRODUCTION Inverters and generators are essential for backup power. Inverters convert DC to AC power, ideal for small devices. Generators produce electricity by burning fuel, suitable for larger appliances. Each has its pros and cons, depending on your needs .

3. 17-Aug-25 3 Generators came first (1830s), invented by Michael Faraday. → They convert fuel into electricity using mechanical motion. → Used in factories, power plants, and homes for backup power. Inverters are newer (1950s–70s), developed with electronics. → They convert battery (DC) power into AC electricity. → Grew in use with solar systems, battery storage, and quiet backup needs. HISTORY

4. Inverter vs. Generator 17-Aug-25 4 Feature Inverter Generator Power Source Converts DC (battery/solar) to AC Produces AC power via fuel combustion Fuel Type Battery (charged by grid, solar, etc.) Gasoline, diesel, propane, or natural gas Noise Virtually silent Usually noisy (unless inverter-type) Maintenance Minimal (mostly battery health) Regular oil changes, fuel filters, etc. Startup Time Instant (or auto-switch) Few seconds delay (manual or auto-start) Usage Time Limited to battery capacity As long as you have fuel Portability Often lightweight and compact Heavier and bulkier

5. 🔧 Troubleshooting: Generator 17-Aug-25 5 Problem Possible Causes Fix Won’t start Empty fuel, bad spark plug, low oil Refill fuel, clean/replace spark plug Low/no output power Faulty AVR, tripped breaker, bad wiring Check AVR, reset breaker, test output Engine runs rough Dirty air filter, old fuel Clean filter, drain/replace fuel Shuts down suddenly Overload, low oil sensor triggered Unplug load, check oil level Noisy operation Loose parts, poor maintenance Tighten bolts, service regularly

6. Troubleshooting: Inverter 17-Aug-25 6 Problem Possible Causes Fix Inverter not turning on Low battery, loose wires, blown fuse Recharge battery, check connections Beeping or alarm Low voltage, overload, overheat Reduce load, check ventilation No output (AC side) Output fuse blown, fault mode Reset inverter, check for short circuit Frequent switching/off Bad battery, unstable input, faulty ATS Replace battery, check ATS/wiring Overheating Poor ventilation, overload Improve airflow, reduce connected load

7. 17-Aug-25 7 Inverter generators – Quieter, fuel-efficient, cleaner power Dual fuel – Runs on gasoline and LPG Auto start via ATS – Automatically turns on during power cuts Compact & portable designs – Easier to carry, store Digital display – Shows voltage, runtime, errors Generator – Feature Trends

8. 17-Aug-25 8 Lithium battery integration – Longer life, faster charging Hybrid systems – Solar + grid + generator compatible Smart inverters – App control, remote monitoring Pure sine wave standard – Safer for electronics All-in-one units – Built-in MPPT, battery, inverter, UPS in one box Inverter – Feature Trends

9. 17-Aug-25 9 An inverter converts stored electrical energy (usually from a battery) into AC power, making it quiet, clean, and ideal for short-term or indoor use. A generator , on the other hand, produces electricity by burning fuel (like petrol or diesel), making it suitable for longer power outages and heavy loads but noisier and more polluting. CONCLUSION
