2. Charge controller - Wikipedia

   en.wikipedia.org/wiki/Charge_controller

   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. Higher array voltage means lower array current, so the savings in wiring costs can more than pay for the controller. [citation needed] Charge controllers may also monitor battery temperature to prevent overheating.

3. Maximum power point tracking - Wikipedia

   en.wikipedia.org/wiki/Maximum_power_point_tracking

   [7] [8] MPPT samples cell output and applies the proper resistance (load) to obtain maximum power. [9] MPPT devices are typically integrated into an electric power converter system that provides voltage or current conversion, filtering, and regulation for driving various loads, including power grids, batteries, or motors.

4. Lithium-ion battery - Wikipedia

   en.wikipedia.org/wiki/Lithium-ion_battery

   A lithium-ion or Li-ion battery is a type of rechargeable battery that uses the reversible intercalation of Li + ions into electronically conducting solids to store energy. In comparison with other commercial rechargeable batteries, Li-ion batteries are characterized by higher specific energy, higher energy density, higher energy efficiency, a longer cycle life, and a longer calendar life.

5. Battery management system - Wikipedia

   en.wikipedia.org/wiki/Battery_management_system

   A battery management system (BMS) is any electronic system that manages a rechargeable battery (cell or battery pack) by facilitating the safe usage and a long life of the battery in practical scenarios while monitoring and estimating its various states (such as state of health and state of charge), [1] calculating secondary data, reporting that data, controlling its environment ...

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. Battery charger - Wikipedia

   en.wikipedia.org/wiki/Battery_charger

   Other battery types cannot withstand over-charging, becoming damaged (reduced capacity, reduced lifetime), over heating or even exploding. The charger may have temperature or voltage sensing circuits and a microprocessor controller to safely adjust the charging current and voltage, determine the state of charge, and cut off at the end of charge ...

8. 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).

9. Tesla Powerwall - Wikipedia

   en.wikipedia.org/wiki/Tesla_Powerwall

   The Tesla Powerwall is a rechargeable lithium-ion battery stationary home energy storage product manufactured by Tesla Energy. The Powerwall stores electricity for solar self-consumption, time of use load shifting, and backup power. [1] [2] The Powerwall was introduced in 2015 as Powerwall 1 with limited production.
