Charge regulators sit between the solar panel and the batteries that store the energy collected by the photovoltaic panels. They regulate the volts and amps flowing from the solar panel into the battery. These regulators serve a number of purposes, including: protecting batteries from overcharge; preventing battery energy from flowing back to the solar panels when the sun isn't shining; providing information about the status of the battery charge and the flow of electricity from the solar panels. Our house uses five Solar Boost 3048 charge regulators, with an output current rating of 24 amps. The 1.1kW units will be located in the attic.
