Validating that your installation is correct
If...
Then...
Otherwise...
Circuit current rating is less
than the R-coil rating.
The correct size R-coils
are installed.
Contact Wattwatchers
support.
Install data shows three
voltages around 220V, less
than 265V.
The voltage connections
are good.
Check the voltage
connections to P1, P2, P3
are three phases.
Three-phase solar inverter
circuits that have equal
current and PF=1.
Solar R-coils are
installed correctly.
Check R-coil wiring, phase
and orientation.
With the solar inverter
turned off, PF is +ve and
expected value on all
circuits.
Grid and load R-coils are
installed correctly.
Ensure R-coil phase and
orientation are correct.
R-coils on the wrong
phase may cause negative
PF readings. Where there
is solar operating, Grid
circuits show -ve PF if
there is “feed in”.
Current measured with
tongs meter is the same
as current reported in
the data.
The Auditor is
configured correctly.
Check R-coil rings are
fully rotated to the locked
position. Use onboarding
tools to change the R-coil
to the correct size.
