  2. Maximum power point tracking - Wikipedia

    en.wikipedia.org/wiki/Maximum_power_point_tracking

    Solar inverters convert DC power to AC power and may incorporate MPPT. The power at the MPP (P mpp ) is the product of the MPP voltage (V mpp ) and MPP current (I mpp ). In general, the P-V curve of a partially shaded solar array can have multiple peaks, and some algorithms can get stuck in a local maximum rather than the global maximum of the ...

  3. Charge controller - Wikipedia

    en.wikipedia.org/wiki/Charge_controller

    Considerable efficiency gains can be achieved, particularly when the PV array is located at some distance from the battery. By way of example, a 150 volt PV array connected to an MPPT charge controller can be used to charge a 24 or 48 volt battery.

  4. Power optimizer - Wikipedia

    en.wikipedia.org/wiki/Power_optimizer

    A power optimizer is a DC to DC converter technology developed to maximize the energy harvest from solar photovoltaic or wind turbine systems. They do this by individually tuning the performance of the panel or wind turbine through maximum power point tracking, and optionally tuning the output to match the performance of the string inverter (DC to AC inverter).

    For example, Alcoa's Warrick Operation is participating in MISO as a qualified Demand Response Resource, [34] and the Trimet Aluminium uses its smelter as a short-term mega-battery. [ 35 ] Latency of the data flow is a major concern, with some early smart meter architectures allowing actually as long as 24 hours delay in receiving the data ...

  7. Switched-mode power supply - Wikipedia

    en.wikipedia.org/wiki/Switched-mode_power_supply

    Stand-alone switched-mode power supply An adjustable switched-mode power supply for laboratory use. A switched-mode power supply (SMPS), also called switching-mode power supply, switch-mode power supply, switched power supply, or simply switcher, is an electronic power supply that incorporates a switching regulator to convert electrical power efficiently.

  8. Maximum power transfer theorem - Wikipedia

    en.wikipedia.org/wiki/Maximum_power_transfer_theorem

    Simplified model for powering a load with resistance R L by a source with voltage V S and resistance R S.. The theorem was originally misunderstood (notably by Joule [4]) to imply that a system consisting of an electric motor driven by a battery could not be more than 50% efficient, since the power dissipated as heat in the battery would always be equal to the power delivered to the motor when ...

    Users with a simple phone or without the app can still receive money if the phone number is registered in the internet bank. Like many other mobile payment system, its main obstacle is getting people to register and download the app, but it has managed to reach a critical mass and it has become part of everyday life for many Swedes.
