Information on Zero Export Devices

• 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

Inverter Control/Solar PV Production

• 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.

2.1 Compatible Inverters

• 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.
