The Zero Export Device has a power analyser, data logger and controller all assembled together which comes as a single component solution. The Zero Export Devices are available in single & three phase models suiting to various types of inverters and manufactures.
OZTRON Reverse Power Controller (RPC) actively modulates the solar inverters even under rapidly fluctuating loads and varying solar output to ensure that the solar power is always maintained just below the consumption level and tripping is avoided. This causes inconvenience and would result in loss of production. The Grid Protection Relay mandated by the Network Provider would trip the Solar Generator under such a situation. While this may be fine on a working day, for a week-end or a holiday the PV generation may exceed the demand. Some commercial Solar PV installations are for self-consumption only and grid export is not permitted.
