what is 5kv when converted to watts?

Question

I need to buy 5kv inverter.the shops are quoting in watts.Thanks for your anticipated answer[s]

Answer 1

You need to know the current.

Power [watts]= Voltage [volts] * Current [amps]

Answer 2

To try to summarize the above answers and perhaps explain how you're getting into trouble...

I think you are mistaken in your need for 5KV. Rarely do people need 5,000 volts (5 kilovolts) to power a device. You are probably looking for 5KVA (5 kilovolt-amps) based the information provided in a spec sheet for the device you are wanting to power with an inverter.

5KVA (5 kilovolt-amps) for resistive loads (like light bulbs) is equivalent to 5KW (5 kilowatts). For motors and other devices, it's not quite the same thing. Not knowing what you want to power, it's difficult to tell you the equivalent watts (due to something called Power Factor Correction), but the industry standard for motor based equipment is to assume 60%, in which case 3KW would be equal to 5KVA.

You're safer just going with 5KW (kilowatts). Shop for that.

Also, understand that what you're asking for won't come cheap. A 48VDC to 120VAC inverter at 5KW looks something like you'll find at the following link (check the UNV48-5.0F unit on the far right column). Won't surprise me a bit if you discover that a true sinusoidal inverter of this power comes with a $5,000 price tag. This is the sort of thing you'd find in a telecom system. If your requirements aren't as strict, I've seen them for half that.

Answer 3

You will need to know both voltage and wattage of the device(s) you want to feed with the inverter

5 kV is the voltage at which the machine/device runs, but you still need to know what kind of power (watts) is required. If the device nameplate does not show Watts, you can calculate it using number of phases (1 or 3) and either full load amps or kVA.

Hope that helped a bit?

Answer 4

Kv To Watts Conversion

Answer 5

5 kv is a voltage. 5 KVA is a power rating which is expressed in terms of watts.
