A garden solar lamp A child in Zambia studying by the light of a lamp charged by solar power during the day. A solar lamp, also known as a solar light or solar lantern, is a lighting system composed of an LED lamp, solar panels, battery, charge controller and there may also be an inverter.
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 [191] 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 [192]

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. Such type of solar charger setups generally use an intelligent charge controller.
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 industrial settings such as telecommunications racks, bulk power may be distributed at a low DC voltage (e.g. from a battery backup system) and individual equipment items will have DC/DC switched-mode converters to supply required voltages. A common use for switched-mode power supplies is an extra-low-voltage source for lighting.
