The Sonel PVM-1020 meter is probably the world's smallest photovoltaic system meter with such a substantial number of measurement functions.
The functions are selected with a rotary switch. Additional parameters are set with buttons located on the housing. All buttons and the graphic display are backlit, which greatly facilitates operation in shaded places, e.g. when taking measurements under ground-mounted PV systems.
Large memory significantly shortens preparation of documents after the measurement.
