System Overview - CARLO GAVAZZI BTM-T7-24 Manuel De L'utilisateur

Energy management
The BTM-T7 logs all the electrical variables collected from Carlo Gavazzi energy meters
(EM21, EM24, EM26, WM30). Instant values are shown in a line chart coupled with icons
(e.g. emoticons) in order to let the user see and understand the various consumptions. All
the logged data is then shown on a bar graph so that a weekly, monthly or yearly overview
can be seen by the home owner.
The various consumptions of electric, water and gas are expressed according to the entered
tariffs, with the opportunity to manage them divided into 4 time bands.
Photovoltaic plant
The BTM-T7 can also be connected to the Carlo Gavazzi solar inverters ISMG3 and ISMG1,
letting the user see how much power he has produced, how much revenue he has earned,
and if there is any alarm in the system.
All the collected data are shown throughout the year with graphical and analytical yield
trends.
