Action Instruments

Amit Somla from Action Instruments in action training the new members at SolarSaver on the Sonel - Measurement Instruments PVM1021 Photovoltaic Meter. This compact, professional photovoltaic meter is used for commissioning, diagnostic, and safety testing of solar systems up to 1000 V. It performs essential Category 1 tests (per EN 62446-1) and can automatically convert test results to Standard Test Conditions (STC) using a wireless link as well as multiple measurement functions.
