Abstract
A method, circuit and system arrangement is described for providing rapid de-energization for safety reasons of conductors having a DC power source at both ends. The invention is particularly envisaged for use in solar energy systems in which a battery is charged by solar power from a photovoltaic array, the invention comprising controlling the array to interrupt charge current flow and then isolating the battery from the conductors to be de-energized in a fail-safe manner.
