How to test the open circuit of photovoltaic battery string
There are many different methods of testing strings and PV Modules. This article is just an overview of the different methods available. IMPORTANT: While most of these tests are commonly used in array fault localization and troubleshooting, some cannot be performed with a Tigo MLPE inline (or attached) to the PV-Modules. An open circuit test can be performed to measure the open circuit voltage of the module or the string. The test requires a DC voltage meter, and it helps to detect intermittent connection issues or open sub-circuits inside the. An Earthing Tester measures the resistance of the earth/ground by employing a constant current generator which injects current into the earth between electrode spikes.
