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. Battery charger - Wikipedia

   en.wikipedia.org/wiki/Battery_charger

   A battery charger, recharger, or simply charger, [1] [2] is a device that stores energy in an electric battery by running current through it. The charging protocol—how much voltage and current, for how long and what to do when charging is complete—depends on the size and type of the battery being charged.

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. Comparison of single-board microcontrollers - Wikipedia

   An adaptor board adds a JST connector for a lithium-ion battery, a charger for the battery, and a microSD card slot connected to the SPI pins. NB1A [178] An Arduino-compatible board that includes a battery backed up real-time clock and a four channel DAC. Most Arduino-compatible boards require an additional shield for these resources. NB2A [179]

7. 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 ...
