How many HP is 1kva?

Equivalent kVA and Horsepower Ratings

kVA HP
750 kVA 804.3 HP
875 kVA 938.3 HP
1,000 kVA 1,072 HP
1,125 kVA 1,206 HP

What size generator do I need for 3hp compressor?

A 3 hp compressor needs to be powered by a motor of at least 2.3 kW, and that’s assuming 98% efficiency, which is unlikely at best.

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 can a 4.5 kVA generator power?

‎ A 4.5kVA generator can power a deep freezer, 1 Air conditioner,1 TV, Home theatre and Water pump along with most of the fans and bulbs in the home or small office.

How do I calculate kVA?

Calculate power rating in KVA when you know voltage and output resistance. Use the formula: P(KVA) = (V^2/R)/1000 where R is resistance in ohms. For example, if V is 120 volts and R is 50 ohms, P(KVA) = V^2/R/1000 = (14400/50)/1000 = 288/1000 = 0.288 KVA.

What is kVA and HP?

Hp is the unit of active power and kVA is the unit of apparent power. Apparent power S(kVA) is equal to the 0.746 times of P(HP) real power in HP divided by the power factor. For converting HP to kVA use the below-mentioned formula. S(kVA) = 0.746 x P(HP) / pf.
