Panel builders, installers, engineering department,…Before the multiplication of energy efficiency solutions to install in the small buildings and commercial buildings, you are facing many difficulties to choose the best technology for the energy collection; the one which will address the needs of your customers, while being easy to use and to install.
The lack of information, knowledge and means makes you take a risk and also lose valuable time.
Installing an inappropriate device, partially replying to the technical requirements specifications, calling on a local collaborator whom reliability and reputation remain uncertain, taking a specific programme causing additional cost, is a significant risk factors and does not guarantee the working of your installation.
A lot of panel builders – maybe like you? – do not even respond to a call to tender involving energy efficiency solutions! Yet, theses are increasing demands and you won’t be able to develop your company without incorporating these solutions in and earning this expertise.
Facing this issue, we decided to go into action to test solutions for energy data logger for small buildings and commercial buildings. Here is how we made these tests:
We dissociated two aspects:
- The connectivity of the data logger and the interfacing possibilities
- The configuration of the software (i.e user-friendliness and features)
We’ve rather compared solutions intended for panel buildings and products from manufacturers who propose offers available in the greatest number of countries.

What do you think about our comparison? Feel free to give your opinion on these solutions and let’s exchange about the other options you have in your countries.
Is there any way to measure energy with out disturbing the installation and moniterd wireless
on remote terminal.
Yes you can install current transformers with no need to loosen any wires.
These transformers can be opened to be installed.

Of course a short removal of voltage can be necessary for safety reasons.
This is the informative and useful plate form for the electrical engineers. Thanks for providing good plate form.
Thanks for this information , how we calculate the power factor & diversity factor of any load panel?

Do you mind if I quote a couple of your posts as long as I provide credit and sources back
to your blog? My blog is in the exact same niche as yours and my users would truly benefit from
a lot of the information you present here. Please let me
know if this alright with you. Appreciate it!
how we calculate ( power factor , demand factor , diversity factor ) in a sub distribution board , final distribution board , main distribution board )?
