SONEL - MPI-540PV multifunction meter with a calibration certificate

Sonel multi-function meter for electrical installation parameters is an advanced tool created especially for measuring the parameters of photovoltaic installations. With the help of a single device, it is possible to perform a whole range of tests on the DC and AC side. In addition, the meter is also used to carry out all measurements to determine the safety status of domestic, as well as industrial electrical installations. The presented meter is a device with advanced capabilities, dedicated to specialists operating in the installation and electrical industry. When measuring the parameters of a photovoltaic installation, the meter automatically recalculates the parameters to the STC (Standard Test Conditions) reference conditions. Measurements of voltages, currents and power on the AC and DC side of the inverter will allow to verify its efficiency. After transferring the data stored in the meter's memory to the Sonel PE6 program, it is possible to generate a report on the test parameters of photovoltaic installations. With a view to automating measurements, the meter has been further enhanced with a function for testing residual current circuit breakers in Auto mode. The instrument also has pre-programmed measurement sequences (so-called autotests) by the manufacturer, which can be expanded with own sequences if necessary.
