Solar grid connect, pv-inverter efficiency, transformer, energy, and environment monitoring : PQube3

  • Are you solar epc or owner and looking for PQM to comply with the grid code?

  • How much my energy use and how much I can save from solar?

  • Is there any affect from pv system to my power factor?

  • How about my transformer health and its performance?

  • Is there any affect of harmonics from pv inverter to my system or transformer?

  • How about my pv inverter efficiency?

  • How about the environment of my pv system

  • How about the environment in the MDB room or panel?

The PQube3 power analyzer can answer you all those questions. The ideal of this application is to install the PQube3 at your facility LV or MV to comply with the grid code for pv solar plant or rooftop.


Scenario I: install at LV (indoor)to gain grid code compliance, power sensor for zero export control, energy produce by solar, energy import from the grid, solar system efficiency/pv inverter efficiency, transformer health and efficiency or pv system environment parameters, MDB room environment parameters

  • Use benefits of multi current channels of PQube3 to capture the ac power on MDB solar and now you can compare the power imported from the grid and produce by pv solar system.

  • Use benefits of analog channels to captures the environment parameters of your pv system such as temperature, solar irradiance, and wind speed.

  • Or if you already have the data logger for the environment of pv system then you can use analog channels for measure the dc input of your inverters and now you can compare the dc input and ac output then the efficiency can calculated.

  • And alternatively use analog channels to gain the the transformer health such as temperature, oil level, pressure, vibration or oil conductivity. Implement dual voltage to gain transformer efficiency and transformer losses verification.

  • Use digital input from PQube3 to monitor the protection relay status.

  • Use benefits of ENV2 sensor to capture MDB room environment parameters such as temperature, humidity, pressure and 3-axis vibration.

Scenario II: install at MV (indoor/outdoor) to gain grid code compliance, power sensor for zero export control, energy produce by solar, energy import from the grid, solar system efficiency/pv inverter efficiency, transformer health and efficiency or pv system environment parameters, switchgear room environment parameters.


The multiple PQube3 can be implement and connect to your corporates network. The data can be push to on premise on your corporates network or on cloud.


Now, with PQube3 you can:

  • Get all the power quality parameters of your supply according to IEC 61000 - 4 - 30 class A and grid code compliance and power sensor for zero export control.

  • Get the energy data produced by your pv system and energy imported from the grid.

  • Get the pv system efficiency/pv inverter efficiency

  • Get the transformer health in control and can verify the losses in the transformer

  • Get all the environment parameters of your pv system or in your room/cabinet

  • Get the email alert in real-time, daily, weekly, and monthly report with ready to use information

  • Gain remote monitoring of your pv system, MDB, and transformer and view anywhere in the world on mobile, tablet or pc

  • Gain visibility inside your facility power system, pv system, transformer health, condition monitoring, predictive maintenance and asset management
