Setup
Switching On
After completing and checking the wiring of the supply and the current transformers (CTs), switch on the
zappi
via
the circuit breaker.
zappi
will start-up and the main screen will be presented after a few seconds.
If
zappi
has been installed alongside another
zappi
unit or another
myenergi
device, refer to
Linking Devices
section
for guidance on pairing devices. Also refer to the instruction documentation for the other devices.
Testing
Before leaving site, it is important that a few checks are carried out, ensuring the sensors have been correctly
installed and are functional.
1.
Check that the time and date are correct and are displayed on the bottom left of the main screen. If
they are not present or are incorrect, set the correct time and date in the Other Settings/Time & Date
menu option.
2.
Check that the EV will charge in FAST mode.
3.
Check the Grid Power reading at the top right of the main screen is showing sensible readings and the
direction of power flow is as expected.
4.
With the EV plugged in, switch to ECO mode and check that the charge power is at minimum (about
1.4kW) OR that it is 'tracking' the surplus power (i.e. the Grid Power reading is 0.0kW)
5.
If a Generation CT has been installed, check that the generated power is shown in the top left of the
main screen. If the generation reading is missing, the most likely cause is the associated CT input is
not enabled – see Ct Config on page 29
27
.
If a (!) symbol is displayed in the top left-hand corner then the generation CT needs to be reversed.
If the Grid Sensor is wired to a
harvi
ensure the device settings are set correctly
Remember – only one CT (or three phase set of CT’s) can be set to Grid
