A charge controller is a device controlling the charge of batteries within a PV system by properly managing the current and the battery voltage. Charge controllers protect the battery and ensure the solar system’s efficient operation which in turn delivers a system that will last for years to come.
It is a term that has quite a straightforward principle behind it but has a wide range of applicability and relevance. Perhaps the simplest way of getting your head around the idea of the microgrid concept is to see it as an energy system where there are generators, consumers and necessary components to ensure function, connected electrically by a suitable method. This is effectively just as the name suggests, a scaled-down version of a traditional electrical power grid; a microgrid.
