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.
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.

Frequently Asked Questions
Yes, it comes with 4 voltage sensing leads. 3 Current sensing coils, that can measure up to 600A, and a USB power supply and cable. If you want to measure higher currents, then you have to buy larger Rogowski coils, also available here.
According to the manual only 7 hours, but in our experience the batteries last up to 48 hours (Rechargeable 2500 mAh Duracell). When logging longer periods of time it is recommended to use a USB power supply and connect it to the USB C power supply port on the meter. Alternatively one could also use a large USB power bank, just make sure it is large enough to last the duration you want to log for. A 10 0000 mAh Power bank will last 3 days in our experience.
No, the meter needs to have power supplied to it’s USB C port, either by a USB power supply or a USB Powerbank. If no USB power is connected, then it will stop working as soon as its internal batteries are flat, after about 72 hours.
The amount of space required for one day’s logging at 1-minute intervals is 1 kB. So, on a 4 GB SD card, one can log for more than 8 years.
At ten-second intervals, it will be, six times more data, that will work out to about 4.5 MB per day. So, one will be able to log for about 1.3 years on a 4GB SD card.
The amount of space required for one day’s logging at 1-minute intervals is 1 kB. So, on a 4 GB SD card, one can log for more than 8 years.
Each meter is factory-tested and calibrated. The allowable variance is less than 0.02% Click here to see an example 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.
If you are using CTs then use the ratio specified on the CT, however, if you are using Rogowski coils then there is no ratio to be set. You can set the option to use CTs or the Rogowski coils under “Wire settings” in the menu, then “iCon” (Current Connection). So use “CTCon” for CTs and “RCoilCon” for Rogowski coils.
It is possible that your loads can generate negative reactive energy. Read this article on Wikipedia.
The maximum size that can be used with the meter is 32 GB, please ensure the SD card size is 32 GB or smaller. Also, the SD card must be formatted with the FAT 32 file system. Please format the SD card on your computer with the FAT 32 File system.
The current value may not be displayed if the duration that the current flows, is below 1 second. The current is still measured and taken into account for the energy consumption. So if the current flows for very short periods of time, then it will not be recorded. The overall energy usage will still be recorded accurately
Another reason is if the 3000A coil is used, and the current flow is less than 3A, then it can not be measured.
It seems that there might be an error in the wiring configuration. Please confirm if it is set to 3-phase 4-wire (3PH4W).

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.
