This three-phase energy logger is ideal for the following.

  • Determining the energy usage/load profile of a building’s energy usage over a period of time.
  • Determining a building’s peak power usage.
  • Testing the quality of supply for example voltage dips and harmonic analysis, and establishing if voltage levels are in the acceptable range for PV Inverters.
Power consumption graph

The results from the energy logging can be used for the following.

  • Accurately plan solar PV systems, to determine what amount of panels are needed.
  • Accurately plan backup power systems, to determine the size of the inverter and battery capacity needed.
  • Accurately plan, backup generator size requirements.
  • Identify cost-saving opportunities from energy efficiency measures.
  • Identify cost-saving opportunities from improving a building’s Power Factor
  • Identify cost-saving opportunities from Peak-demand(KVA) requirements (Monitor what is causing high KVA usage and when).
  • Monitor and check for phase imbalances to prevent overloading one phase.

Meter data analysis, visualisation and reporting

We have created an Excel template that can analyse the data and visualise it with graphs. It has the following features and graphs.

  • Maximum power per minute, hour and day
  • Energy usage per minute, hour and day
  • Maximum voltage per minute, hour and day
  • Limit data displayed to a specific day or hour
  • Supports three-phase and single-phase setups

This template and support with importing the data and using the template are included free of charge when purchasing this meter.

The template is very easy to use even for users that is not that familiar with Excel. We have also created step by step instructions document and video.

Frequently Asked Questions

Yes, it comes with 4 voltage sensing leads, 4 current sensing coils, and a USB power supply and cable. The diameter of the current sensing coils is 24mm and it can measure up to 600A, If you want to measure higher currents, then you have to buy larger Rogowski coils, also available here.

The build in LiPo batteries last 10 hours. We recommend plugin it into mains power if planning to log for longer than 10 hours.

Each meter is factory-tested and calibrated. The allowable variance is less than 0.02% Click here to see an example factory meter calibration report. Additionally each meter can be sent for calibration and receive a calibration certificate at additional cost. Click here to see an example meter calibration report.

It is possible that your loads can generate negative reactive energy. Read this article on Wikipedia.
