Mains Power Energy Monitoring Configuration
An expanded range of new Wiki pages are being created for IPEM Plus, but also relate to other IPEM, IPEM PiHat and EPEM boards.
What is a Power Energy Monitor?
A power energy monitor is a device that safely samples the AC Voltage, and Current flow, from one, or more, electrical phases, and from this, derives a range of accurate mains power measurements which can then be used for smart metering, or energy monitoring purposes.
These individual measurements can then be extrapolated into a range of useful real-time data such as total RMS Power, Active, Re-Active Power, Harmonic Power, Power Factor, Phase Angles, Frequency, etc.
The purpose of extracting the power energy data within Solar Inverter installations, as an example, will enable you to much better manage what you do with the available energy, ways of storage, EV Charging, divert under certain conditions, and control flow from, and to, the grid.
All this data is far more extended information than the basic electric meter functionality, allowing for smart IoT systems and greater efficient use of our own energy. It may sound complicated but it does not need to be and all depends on your setup, use-case and what you want to achieve.
Installation Types
These pages go through the various aspects and configuration for:
- Single phases (Up to 3 individual current inputs on the same installation, such as ring, kitchen and garage)
- Two phase, Dual phase and Split phase (Typically for USA i.e. 2 x 110V)
- Three-phase three-wire (3P3W, Y or Δ), systems (3 x Live)
- Three-phase four-wire (3P4W, Y0, Three Phase Live with Neutral)
