Sonel MPI-540 PV Electrical tester

Automatically Security inspection of equipment
The device enables the safety inspection of electrical systems in residential, commercial and industrial buildings. Measurements can be easily automated by:
• Testing of residual current circuit breakers in AUTO mode,
• Automatic processes – i.e. freely configurable,
• Use AutoISO-1000C adapters to test the insulation resistance of 3-, 4- and 5-core cables.

Monitoring PV systems
The MPI-540-PV is a versatile and universal measuring device specially developed for the testing of photovoltaic systems. The equipment enables a complete testing of the DC and AC side according to the guidelines of the EN 62446 standard. The measurement parameters of the photovoltaic system are automatically converted by the device into the reference conditions STC (standard test conditions). The efficiency of the inverter can be checked by measuring voltage, current and power on the AC and DC side.
The Sonel REPORTS PLUS software enables the creation of a test report for the photovoltaic system with the saved measurement results in the measuring device.

3-phase power analyzer
The device has a three-phase power analyzer with LIVE mode and the option to register electrical mains parameters such as voltage, current, power, harmonic and THD. The measuring device enables the reading of selected parameters and their graphical display in real time. These parameters are measured and displayed at the same time as recording on the memory card. In LIVE mode, the user can see:
• Voltage and current wave forms (oscilloscope),
• Voltage and current time-range recordings,
• Phasorgraph,
• View of several parameters simultaneously in table form,
• Spectrum graph of current and voltage harmonics.

Brilliant images
The device is equipped with a color TFT LCD touch screen of 800 x 480 pixels and a 7 inch diagonal screen, which enables easy operation and reading of parameters and recorded waveforms. This screen size allows you to view more information at the same time that is currently available. The user interface is easy to read under all lighting conditions. The pen included in the delivery also enables use with insulated gloves.

Integrated help menu
The device has integrated help menus with connection diagrams. Thanks to this, you can quickly and easily check and ensure how you need to connect the device to a specific system, depending on the type of measurement.

Increased resistance
The MPI-540 / MPI-540-PV device is designed for use under difficult environmental conditions. The protection against penetration of dust and water is ensured by the unique IP51 casing. It is also extremely robust to cope with mechanical external influences. A special design of the lid also protects the display against damage. Despite the design for protecting the device, it is nevertheless comfortable to use and transport.

Interfaces and software
The numerous communication interfaces and the cooperation with external software are to be highlighted. Transfer readings to your computer via a USB port, removable SD memory cards, or wireless (Bluetooth, Wi-Fi). To report electrical shock protection measurements, use the Sonel REPORTS PLUS software. The saving of the downloaded data in the most common formats and the printing is done via the free software Sonel reader. The special, free Sonel analysis software serves for reading and analyzing the data of the power analyzer.
