A With a Net Feed In Tariff FIT this is determined by how much energy your ZEN Energy System is generating and how much you are using Any excess or unused energy is exported to the grid Example 1 Export mode putting energy back into the grid for any given period If your ZEN Energy System has generated 5kWh and you have used 2 5kWh then 2 5kWh will be put back exported to the grid during that time Example 2 Import mode importing energy from the grid for any given period If your ZEN Energy System has generated 5kWh and you have used 7 5kWh then you have used imported 2 5kWh from the grid Q Why is the reading on my ZEN Energy System not the same as the import export meter A The reading on your display on your ZEN Energy System shows the Gross or total amount of energy being generated by your ZEN Energy System at that time The import export meter only shows the excess amount of solar energy your ZEN Energy System has put back into the grid Varying home electricity usage with a Net Feed In Tariff system will also cause major differences of these two values Q Will my ZEN Energy System be able to generate power for use during a power failure A No for safety reasons your ZEN Energy System will automatically turn off during a network power failure It will also automatically turn back on again once the power has been restored This feature is mandatory as it protects grid line workers who may periodically need to carry ou
