What is an Insulation Tester for PV (photovoltaic) systems?

QWhat is the difference between a general insulation tester and the Insulation Tester IR4053 model ideal for PV systems?


The Insulation Tester IR4053 for solar power systems has a dedicated PV function "PVΩ".
The PV dedicated function "PVΩ" can be used to measure the insulation resistance between the solar panel and ground without being affected by power generation.
Turn off any disconnector devices and separate from the power conditioner before starting the measurements for the solar battery panel.

Use the normal insulation resistance range when measuring between the junction box output terminal and ground and between the power conditioner and ground.
