What is a Kilowatt (kW)?
The demand limit and usage displayed on the demand controller is measured by kilowatts
(kW). One kW is equal to 1,000 watts. For example, if you have ten 100 watt light bulbs
on at one time, the demand is 1,000 watts or 1 kW. If they remain on for one hour, the
energy used is one kilowatt-hour (kWh).
