Solar Reverse Panel
The Zero Export Devices are available in single & three phase models suiting to various types of inverters and manufactures. The Zero Export Device has a power analyser, data logger and controller all assembled together which comes as a single component solution. At any time, the ZERO EXPORT prevents the solar system from feeding in to the grid and DG SET. The Reverse power protection panel is located close to the Solar AC distribution board. It can operate in stand-alone mode or interface with the Grid Protection Relay for added features and simpler installation. The grid voltage provides the power supply for the relay energising circuit and phase reference for the phase sensitive detector. Current reference to the detector is taken from generator load current The output from the detector is compared with a reference which is set by the trip set point potentio meter. When the set point value is exceeded an electronic trip operator to energise the relay circuit though an adjustable time delay.
