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 ...
In the context of domestic PV installations, the kilowatt (symbol kW) is the most common unit for nominal power, for example P peak = 1 kW. Colloquial English sometimes conflates the quantity power and its unit by using the non-standard label watt-peak (symbol W p), possibly prefixed as in kilowatt-peak (kW p), megawatt-peak (MW p), etc.
A power inverter, inverter, or invertor is a power electronic device or circuitry that changes direct current (DC) to alternating current (AC). [1] The resulting AC frequency obtained depends on the particular device employed. Inverters do the opposite of rectifiers which were originally large electromechanical devices converting AC to DC.

The generator, which is approximately 34% of the wind turbine cost, includes the electrical generator, [64] [65] the control electronics, and most likely a gearbox (e.g., planetary gear box), [66] adjustable-speed drive, or continuously variable transmission [67] component for converting the low-speed incoming rotation to high-speed rotation ...
The Smartstream G2.5 GDi is an inline 4-cylinder engine with both direct and multi-port injection and a 13.0:1 compression ratio; the engine makes 194 PS (191 hp; 143 kW) at 6,100 rpm and 25 kg⋅m (181 lb⋅ft; 245 N⋅m) of torque at 4,000 rpm in the Sonata, for the Azera and Cadenza the engine makes 198 PS (195 hp; 146 kW) at 6,100 rpm and ...
By 1998, Huawei had signed agreements with municipal and provincial telephone bureaus to create Shanghai Huawei, Chengdu Huawei, Shenyang Huawei, Anhui Huawei, Sichuan Huawei, and other companies. The joint ventures were actually shell companies, and were a way to funnel money to local telecommunications employees so that Huawei could get deals ...
For fossil fuels the free enthalpy of reaction is usually only slightly less than the enthalpy of reaction so from equations and we can see that the energy efficiency will be correspondingly larger than the energy law efficiency. For example, a typical combined cycle power plant burning methane may have an energy efficiency of 55%, while its ...
The DOHC 16-valve powerplants were mated to a second generation common rail injection system and a variable-geometry turbocharger, pushing power to 136 PS (100 kW; 134 hp) (RHR). It is fitted with a six-speed manual transmission or six-speed Aisin- automatic transmission (in Citroën C5 from summer 2004 onwards).
