It features a photovoltaic resistance function that can safely and accurately measure PV insulation resistance even while generating solar power.

Using normal methods, short-circuiting is usually needed when measuring a generating PV to get an accurate result; however, with the IR4053’s PV measurement mode, this is not necessary. Thanks to its special designed specs it can still provide precise measurements without being affected by generated power that would normally interfere with traditional insulation testers.

The five ranges (50/125/250/500/1000V) make it easy to perform normal insulation resistance measurements. Furthermore, it has a built-in 1000 VDC voltage measurement for open voltage tests of PV systems that support 1000 V as well as a comparator function and drop-proof design that withstands drops onto concrete from 1 meter high.

With its ease of use and wide range of functions, the Hioki IR4053 Insulation Tester is an indispensable tool for photovoltaic generation system applications.
