Advanced module view and waveform:

Set channel phase:

To correctly compute the active power in three phase panels, each current sensor must be set with the matching phase line which powers the current sensor wire. The Phases 1, 2 and 3 respectively match the voltage inputs L1,L2 and L3. The x phase to be set is the one for which the voltage between the wire and the concentrator's Lx input is null (the others are around 400 Volts). In the case of a mono phase panel, all channels must be set to the only phase (usually L1) which powers the concentrator.
To not forget to configure a phase, you can use the initialization function on the touchscreen module (cf next video)

Initialize a Multivoies system:

Set Clock:

Set recording period:

With Multivoie system, data are continuously recorded. A period change creates a new line in the data file with the time the change occurred.

Download datas to SD card:

GPRS module:

Before using GPRS module, you must create the correct folder on the ftp server \"FTP folder set in GPRS module"\"Concentrator SN"\
(example : \0002\01001224\)

The GPRS module list must be up to date (button UPD. LIST)


Multivoies is a multi channel electricity metering and monitoring system dedicated to detailed analysis of the electricity bill. It is modular, compact and can be easily and quickly installed in all kinds of switchboards. The variety of miniaturized, openable or flexible current sensors offers a wide range of power measurement from 0 to 120 kW per phase. Multivoies acts also as a platform for wireless sensors monitoring all the building parameters : pulse, temperature, humidity…It has a user-friendly wireless (infrared or radio) local interface on a PDA or PC enabling the setup and the real-time display of power loads on all channels. GPRS and Ethernet additional devices allow the transfer on a server and the analysis of the data on your computer wherever you are. Primarily designed for short term monitoring campaign, it can also be implemented for permanent surveys.
