How does it work?

PhiSaver monitors up to 14 sub-circuits and provides highly reliable operation without batteries or maintenance.

A mobile-phone-sized data collector is installed in your switchboard, and connects via WiFi.

Individual circuits (up to 14) are monitored continuously. The data is stored in the cloud for viewing.

Consumption by circuit is available via phone or PC.

Solar and battery systems can be integrated into the system.

How is it different?

Simple wireless energy monitors only monitor the whole-of-building usage and, being battery powered, are notoriously unreliable. In-built solar panel systems monitor only solar and whole-of-building usage.

What savings are available?

  • Identify faulty equipment (10-30% savings): poorly configured hot water systems, high standby load air-conditioners, over-running pool and hot water pumps.
  • Identify energy hungry appliances (0% – 20% savings): older fridges and outside lights can be economically replaced.
  • Awareness (5% – 20%): a quick glance at your monitor before leaving the building, or going on holidays can prevent inadvertent wastage.
  • Maximise solar use (0% – 30%): track your solar production and configure equipment to run when you have surplus energy.
