2. Power rating - Wikipedia

   en.wikipedia.org/wiki/Power_rating

   Audio amplifier power ratings are typically established by driving the device under test to the onset of clipping, to a predetermined distortion level, variable per manufacturer or per product line. Driving an amplifier to 1% distortion levels will yield a higher rating than driving it to 0.01% distortion levels. [14]

3. Grid-tie inverter - Wikipedia

   en.wikipedia.org/wiki/Grid-tie_inverter

   A grid-tie inverter converts direct current (DC) into an alternating current (AC) suitable for injecting into an electrical power grid, at the same voltage and frequency of that power grid. Grid-tie inverters are used between local electrical power generators: solar panel , wind turbine , hydro-electric , and the grid.

4. List of Yamaha Corporation products - Wikipedia

   Yamaha recommend that this device be used with the Yamaha VL70m Virtual Acoustic Tone Generator. The WX7 was the first model that Yamaha produced, beginning in 1987. [ 43 ] This was followed by the WX11 in 1993, [ 44 ] and then the WX5 in 1999—2001. [ 45 ]

5. Volt-ampere - Wikipedia

   en.wikipedia.org/wiki/Volt-ampere

   Some devices, including uninterruptible power supplies (UPSs), have ratings both for maximum volt-amperes and maximum watts. A common prefixed derived unit is "kilovolt-ampere" (symbol kVA). The VA rating is limited by the maximum permissible current, and the watt rating by the power-handling capacity of the device.

6. Rating plate - Wikipedia

   en.wikipedia.org/wiki/Rating_plate

   A typical electrical generator rating plate contains the following parameters: [4] power rating is specified in terms of apparent power (KVA or MVA), since the exact power factor will be determined by the external factors; [5] power factor (PF) is the nominal power factor for other ratings; usually PF = 0.8; [5]

7. Inverter-based resource - Wikipedia

   en.wikipedia.org/wiki/Inverter-based_resource

   An inverter-based resource (IBR) is a source of electricity that is asynchronously connected to the electrical grid via an electronic power converter ("inverter"). The devices in this category, also known as converter interfaced generation ( CIG ), include the variable renewable energy generators (wind, solar) and battery storage power stations ...
