   Sales prices of single-family homes across New York decreased by 10.1% from a median of $344,828 in October to $310,166 in November. Since November 2022, the sale price of single-family homes ...

3. Power inverter - Wikipedia

   en.wikipedia.org/wiki/Power_inverter

   Sine wave. A power inverter device that produces a multiple step sinusoidal AC waveform is referred to as a sine wave inverter. To more clearly distinguish the inverters with outputs of much less distortion than the modified sine wave (three-step) inverter designs, the manufacturers often use the phrase pure sine wave inverter.

4. Grid-tie inverter - Wikipedia

   en.wikipedia.org/wiki/Grid-tie_inverter

   Inverters that target commercial applications are available for 208, 240, 277, 400, 480 or 600 VAC and may also produce three phase power. Peak efficiency: The peak efficiency represents the highest efficiency that the inverter can achieve. Most grid-tie inverters on the market as of July 2009 have peak efficiencies of over 94%, some as high as ...

   Internal view of a solar inverter. Note the many large capacitors (blue cylinders), used to buffer the double line frequency ripple arising due to single-phase ac system.. A solar inverter or photovoltaic (PV) inverter is a type of power inverter which converts the variable direct current (DC) output of a photovoltaic solar panel into a utility frequency alternating current (AC) that can be ...

7. Harmonics (electrical power) - Wikipedia

   en.wikipedia.org/wiki/Harmonics_(electrical_power)

   Because this is a deviation from a pure sine wave, the deviation is in the form of a periodic function, and by definition, the voltage distortion contains harmonics. When a sinusoidal voltage is applied to a linear time-invariant load, such as a heating element, the current through it is also sinusoidal. In non-linear and/or time-variant loads ...

8. Resonant inverter - Wikipedia

   en.wikipedia.org/wiki/Resonant_inverter

   This type of inverter produces an approximately sinusoidal waveform at a high output frequency, ranging from 20 kHz to 100 MHz, and is commonly used in relatively fixed output applications, for example, induction heating, sonar transmitters, fluorescent lighting, or ultrasonic generators. Due to the high switching frequency, the size of the ...

9. New York City steam system - Wikipedia

   en.wikipedia.org/wiki/New_York_City_steam_system

   Approximately 30% of the ConEd steam system's installed capacity and 50% of the annual steam generated comes from cogeneration. [7] Cogeneration and Heat Recovery Steam Generation (HRSG) significantly increase the fuel efficiency of cogenerated electricity and thereby reduce the emission of pollutants, such as NOx, sulfur dioxide, carbon dioxide, and particulate matter, as well as the city's ...
