Multifunctional meter

• High quality
• Stainless steel

Multifunctional meter for comprehensive installation analysis. The Sonel MPI-540-PV meter is an advanced tool designed for comprehensive diagnostics of electrical installations, both in residential and industrial buildings, especially those equipped with photovoltaic systems. The device combines the functions of many specialized meters, providing precise measurements and facilitating verification of compliance with applicable standards, including PN-EN 62446. This makes it indispensable for installers, service technicians and those responsible for energy safety and efficiency.

The MPI-540-PV meter allows for a full range of photovoltaic installation tests, from measuring DC and AC parameters to analyzing inverter efficiency and detecting potential shading problems. Automatic conversion of results to STC (Standard Test Conditions) simplifies comparison with catalog parameters and evaluation of system performance. Additionally, the device allows for recording measurement data and generating reports, which significantly streamlines the documentation and analysis process.

Functionality and application

The MPI-540-PV meter offers a wide range of measurements, including:

• Photovoltaic installation measurements: protective conductor continuity, grounding resistance, DC insulation resistance, open circuit voltage (UOC), short circuit current (ISC), DC and AC currents and powers, and inverter efficiency.
• Electrical measurements: loop impedance, RCD parameters (automatic test), insulation resistance, grounding resistance (various measurement methods), protective and equalization conductor continuity, illumination intensity, and phase sequence test.
• Power quality analysis: alternating voltage and current (TRMS), active, reactive and apparent power, power factor (PF), harmonic voltage and current, and total harmonic distortion (THD).
• Data logging: ability to save measurement results in the device's memory and transfer them to a computer via USB or wirelessly (Bluetooth/Wi-Fi).

Thanks to this, the meter finds application in:

• Acceptance of electrical installations: verification of compliance with standards and regulations.
• Service and maintenance: troubleshooting and assessment of the technical condition of installations.
• Photovoltaic installations: measurements of PV system operating parameters and evaluation of its performance.
• Power quality control: analysis of grid parameters and detection of disturbances.

Comfort of use and additional functions

The MPI-540-PV meter is equipped with a number of features that increase comfort of use:

• Large 7” touchscreen LCD: provides a clear display of measurement parameters and intuitive operation.
• Built-in help system: contains measurement diagrams to facilitate correct device connection.
• Software update capability: provides access to the latest features and fixes.
• Removable microSD card: allows easy expansion of the device's memory.
• Li-Ion battery power supply: provides long operating time without the need to replace batteries.
• LoRa wireless communication: enables communication over longer distances than Bluetooth!
• Automatic data synchronization: reSYNC function facilitates work with multiple devices simultaneously.

Thanks to this, the Sonel MPI-540-PV is not only a precise meter, but also a user-friendly tool that significantly streamlines the work of professionals involved in electrical and photovoltaic installations. A set with F-3A flexible clamps and IRM-1 solar power meter expands the diagnostic capabilities of the device with measurements of solar irradiance and temperature of photovoltaic panels – key parameters affecting the efficiency of the entire system.
