  1. Zero Export DevicesZED 1, 2, 3, 4GNT Engineering Zero Export Devices by GNT Engineering is now in administration. If you need help with your solar installations please call BCJ Controls on 02 9534 8465

  2. Zero export devices

  3. The Zero Export Device technology within the ZED family: • Inverter management of solar PV productionMaximum Solar PV production while minimizing grid consumptionZero export to the gridSecondary protection as per AS 4777.3 2005 and IEC 60255-5 and IEC 60255-22 Information on Zero Export Devices:

  4. 1. The ZED devices communicate with the inverter via three (3) protocols, the choice of protocol is dependent on specific inverter compatibility. These protocols are 4 or 6 bit binary and RS 485 protocols. The 4 bit binary provides 16 levels of solar PV production between 0 and 100%. The 6 bit binary provides 64 levels of solar PV production between 0 and 100%. 2. RS 485 provides solar PV production in 1% increments. Inverter Control/Solar PV Production

  5. There is a range of inverters that are compatible with the ZED family of devices can manage Solar PV production and deliver Zero Export.Inverters which can be controlled via 4 or 6 bit binary will require a management card supplied by the manufacturer of the inverter; these are often referred to as Power Control Modules, Power Management Units, Data Managers or controllers.Inverters that have RS 485/Modbus connection are managed via inverter specific protocols. Inverter performance and compatibility with the ZED family has been validated by GNT Engineering. • To date a number of inverters have been validated by GNT Engineering and are managing Zero Export solutions for 3 phase and single phase installations. 2.1 Compatible Inverters
