Most properties with a three phase supply will have a single meter for all three phases, so provided your meter is on our compatible meter list all should work fine. The meter will simply report the combined consumption across all three phases to Powerpal combined, giving an accurate read out of the total electricity consumption for your home.
However some older properties may have a seperate meter for each phase. In this situation it will not be possible to monitor all three phases as Powerpal can only be connected to one electricity meter.
If you are unsure if your three phase meter is compatible please email support@powerpal.net with a photo of your switchboard and we'll be happy to check for you.
