Multifunctional meter of electrical installation parameters from the manufacturer Sonel. The product catalog number is WMPLMPI540PV. It is an advanced tool created in particular to measure the parameters of photovoltaic installations. With the help of one device, it is possible to perform a whole range of tests on the DC and AC side in accordance with the guidelines of the PN-EN 62446 standard. It is also used to carry out all measurements to determine the safety of home and industrial electrical installations. during the measurement of the parameters of the photovoltaic installation, the meter automatically recalculates the parameters to the reference conditions STC (Standard Test Conditions). Measurements of voltages, currents and power on the AC and DC side of the inverter will verify its efficiency. After transferring the data stored in the meter's memory to the Sonel PE6 program, it is possible to generate a test report on the parameters of photovoltaic installations. The meter has been additionally equipped with the function of testing residual current circuit breakers in Auto mode. The device also has measurement sequences pre-programmed by the manufacturer (so-called self-tests), which can be expanded with your own sequences if necessary.
