What size generator do I need for a 3 hp compressor?
Strictly speaking 3hp will be a 3kw, but no way will a small 3kw generator cope with a big electric motor starting current. I’d think you’d want at least double the capacity ie 6kw.
What size generator do I need to run a 3 HP motor?
A generator rated 3 kVA will run a 3 hp motor. The engine that drives the generator may be rated 4 hp. If the motor load is hard starting, then you might need a larger generator, 4–5 kVA. Usually generators are rated in kilowatts, so a 3kW generator could be large enough, 4kW will work ok in most all cases.
How big of a generator do I need to run a air compressor?
Example: A 1 horsepower air compressor with a type L motor draws 10 amps at 120 volts or 1200 watts. 1200 watts x 6 = 7200 watts. A 7200 watt generator is required to run this compressor. Example: A circular saw runs a universal motor at 12.5 amps.
How many watts does a 3 horsepower motor use?
Approximate Running Wattage
| Approximate Starting Wattage | Approximate Running Wattage | |
|---|---|---|
| Capacitor Start Induction Run 1 1/2Horsepower | 4200 | 1600 |
| Capacitor Start Induction Run 2 Horsepower | 5100 | 2000 |
| Capacitor Start Induction Run 3 Horsepower | 6800 | 3000 |
| Capacitor Start Induction Run 4 Horsepower | 9800 | 4800 |
What can you run on a 6.5 KVA generator?

- Refrigerators. Refrigerators can be powered with a 6,500-watt generator.
- Window Air Conditioners.
- Electric Clothes Dryer.
- Televisions.
- Electric water heater.
- Other.
How many kVA is a 3hp motor?
Equivalent Horsepower and kVA Ratings
| HP | kVA |
|---|---|
| 1 HP | 0.933 kVA |
| 2 HP | 1.87 kVA |
| 3 HP | 2.8 kVA |
| 4 HP | 3.73 kVA |
What size generator do I need to run a 2 HP air compressor?
2 HP Air Compressor: 7770 watts for starting wattage and 2800 for running wattage.
How fast is 3 horsepower?
To give you a simple reference, a 3 hp electric outboard can push a 12 ft boat with 150 kg (331 lbs) load at a max speed of 9 km/h (5.6 mph). That’s to say the 3 hp outboard motor can provide more than sufficient propulsion for a 10 ft tender or work as an auxiliary power for a daysailer of up to 1.5 tonnes (3307 lbs).
What size generator do I need to run a 3HP motor?
A generator rated 3 kVA will run a 3 hp motor. The engine that drives the generator may be rated 4 hp. If the motor load is hard starting, then you might need a larger generator, 4–5 kVA. Usually generators are rated in kilowatts, so a 3kW generator could be large enough, 4kW will work ok in most all cases.
What kVA generator do I need to run a motor?
The Full load input of the motor assuming an efficiency of 80\% and a power factor of 0.8 lag the KVA input at FL = 20 x 0.75 / (0.8 x 0.8) = 23.44 KVA. If the motor is started with FL on the shaft and a starter to limit the starting current, may be you will require about 40 to 45 KVA generator.
How many tons of AC can a 20kva generator run?
Keeping in view the values and the relevant factors, one can find a load of 1.5 ton AC. How many ac can run on a 20-kVA generator? A 20-kva generator can run up to 6 air conditioners that consuming 2 500 watts of power each. Because 20 kva is equivalent to 16 000 watts by assuming the power of factor is 0.8.
How big of a generator do I need to run an air compressor?
How big of a generator do I need to run an air compressor? You will need to figure 1800 to 2000 watts for the air compressor needs on start up. I would recommend a 2500 watt generator .
