MBJ Solutions displayed its innovative portable luminescence testing tool, MBJ Quickcheck, at the exhibition
This tool, featuring a battery-powered small imaging camera connected with an adjustable telescopic rod, can take EL images of the operational modules during daylight
The images can be seen through a smartphone or optional VR headsets
At the recent Intersolar Europe 2025, German PV testing equipment manufacturer MBJ Solutions GmbH promoted its innovative portable luminescence tester – MBJ Quickcheck – designed for quick, daylight-enabled, on-site module health checks.
During a brief interaction with the company’s representative, TaiyangNews gained some insights into this latest offering, among others, showcased at the event.
Unlike conventional electroluminescence (EL) testers, Quickcheck can be used in fully operational PV plants during daylight hours for rapid fault diagnostics. This compact, portable, battery-powered EL inspection tool incorporates several advanced features. It includes an imaging system with a 640 × 512-pixel camera and is powered by a 36V, 4.4Ah, 158.4 Wh lithium-ion battery with an integrated charger.
According to the company’s datasheet, the camera is mounted on a telescopic rod adjustable between 106 cm and 300 cm. Live images can be viewed in real-time via smartphones or optional virtual reality (VR) glasses, allowing operators to capture sharp luminescence images even in bright daylight – hands-free, as the company explained. These images can be saved to the system’s integrated computer and later downloaded via Wi-Fi.
Unlike traditional EL testing systems, this tool does not require rewiring of the PV array or shutting down the inverter. It is a cost-effective diagnostic solution that can be operated by a single person, with no need for a licensed electrician. Designed for field efficiency, the Quickcheck can operate for 2 to 3 hours on a single charge, with the battery requiring up to 3 hours for full recharging.
