PV-KLA MUX Fully Automated Multiplexer for PV Module Test Bench

Based on our highly successful PV-KLA electrical characteristic analyser, we have developed a system called the PV-KLA MUX, which can perform fully automated measurements on several photovoltaic modules. The PV-KLA MUX is usually used to record current-voltage characteristics under a range of different natural weather conditions, thus determining real-world behaviours rather than simply performing research using STC. This enables a comparison of different types of modules. This unit can also be used to monitor modules during light soaking.

Our PV-KLA MUX systems are already in use by numerous institutes and manufacturers in the photovoltaics industry.
