Regulators RSS

Solar controllers are used in between the solar panel and the battery.
Most of today’s 12 volt solar panels come in 16-22 volts double for 24volt panels, and obviously batteries are 12 volt. The controller stops the panel from pumping in over charge and regulates the flow whilst allowing for faster or more volts when the battery is low, and slower or less volts as it fills. They then hold a “float” to keep the battery topped up.
Most these days also have USB ports to charge devices at 5volts (USB Voltage) and a spot for a 12 volt accessory.
