  2. Charge controller - Wikipedia

    en.wikipedia.org/wiki/Charge_controller

    In solar applications, charge controllers may also be called solar regulators or solar charge controllers. Some charge controllers / solar regulators have additional features, such as a low voltage disconnect (LVD), a separate circuit which powers down the load when the batteries become overly discharged (some battery chemistries are such that ...

  3. Solar charger - Wikipedia

    en.wikipedia.org/wiki/Solar_charger

    A solar charger is a charger that employs solar energy to supply electricity to devices or batteries. They are generally portable . Solar chargers can charge lead acid or Ni-Cd battery banks up to 48 V and hundreds of ampere hours (up to 4000 Ah) capacity.

    The controller then resumes operation with the voltage controlled at a fixed ratio, such as 0.76, of the open-circuit voltage . [24] This is usually a value that has been predetermined to be the MPP, either empirically or based on modelling, for expected operating conditions.

  5. Solar controller - Wikipedia

    en.wikipedia.org/wiki/Solar_controller

    The simplest solar controller circuit uses a comparator with two temperature inputs, one at the solar panel and one at the thermal store's heat exchanger, and an output to control the pump. Commercial controllers use a microprocessor usually with a LCD display and simple user interface with a few pushbuttons.

  6. Photovoltaic system - Wikipedia

    en.wikipedia.org/wiki/Photovoltaic_system

    A photovoltaic system, also called a PV system or solar power system, is an electric power system designed to supply usable solar power by means of photovoltaics.It consists of an arrangement of several components, including solar panels to absorb and convert sunlight into electricity, a solar inverter to convert the output from direct to alternating current, as well as mounting, cabling, and ...

  7. Stand-alone power system - Wikipedia

    en.wikipedia.org/wiki/Stand-alone_power_system

    Schematic of a stand-alone PV system with battery and charger. In stand-alone photovoltaic power systems, the electrical energy produced by the photovoltaic panels cannot always be used directly. As the demand from the load does not always equal the solar panel capacity, battery banks are generally used.

  8. Solar panel - Wikipedia

    en.wikipedia.org/wiki/Solar_panel

    A photovoltaic system typically includes an array of photovoltaic modules, an inverter, a battery pack for energy storage, a charge controller, interconnection wiring, circuit breakers, fuses, disconnect switches, voltage meters, and optionally a solar tracking mechanism. Equipment is carefully selected to optimize energy output and storage ...

  9. Power inverter - Wikipedia

    en.wikipedia.org/wiki/Power_inverter

    In other applications, a conventional inverter can be combined with a battery bank maintained by a solar charge controller. This combination of components is often referred to as a solar generator. [15] Solar inverters are also used in spacecraft photovoltaic systems.
