How to install
This solar energy monitor will need to be installed by a qualified electrician in most cases. To successfully use this monitor you will need to be able to completely isolate your ‘household consumption’ from ‘solar production’ at your meter board. This is an example of how the unit can be installed:

- The “HOUSE” sensor/transmitter should be installed on the consumption only side of the main power switch at your meter board. It will only pick up your consumption – it doesn’t matter whether that consumption is being supplied by the solar panels or the grid.
- Next, the “SOLAR” sensor/transmitter is installed on the AC output side of the inverter. It will measure solar PV production.
- Finally, the display screen calculates a NET value of the above readings and will show you the approximate amount of power being exported to or imported from the grid.
