Photovoltaic and electrical installation testers
Photovoltaic electrical installation safety testing is a special area of electrical installation safety testing as it also entails tests and measurements on DC systems, which are relatively uncommon in most domestic, commercial and to a certain extent industrial environments. There is also the addition of photovoltaic-specific tests that are outside the realm of standard test and measurement procedures.
Metrel has two dedicated photovoltaic electrical installation safety testers. One representing a complete test and measurement solution with support for line/loop impedance testing, type A, AC, B RCD testing, and power and energy measurements, while the other is a more streamlined testing tool for simplified assessment of photovoltaic installations.
