PV Module Test Bench
PV-KLA MUX
The fully automated Multiplexing PV Module Test Bench
Measure the characteristics of multiple PV modules automatically at the same time with our PVA-KLA MUX multiplexer system. Based on our highly successful PV-KLA curve analyser, this system is able to provide fully automatic I-V curve measurement for various PV modules.
The PV-KLA MUX is typically used to measure current-voltage characteristics under many different natural weather conditions. In this way, real behaviour can be studied in contrast to standard test conditions (STC), allowing comparison between different module types. The system is also used to monitor modules while they undergo light soaking.
Our PV-KLA MUX systems are used for photovoltaics at numerous institutions and manufacturers worldwide.
