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
Germany-based PV health checkup tool maker MBJ Solutions GmbH promoted its latest offerings at the recent Intersolar Europe 2025.
Michael Fuss, Managing Director of MBJ Solutions, briefed the TaiyangNews team about the company’s latest innovative portable luminescence tester, MBJ Quickcheck.
Unlike conventional electroluminescence (EL) testers, Quickcheck can be used in fully operational PV plants during daylight hours for rapid fault diagnostics. According to Fuss, this portable tester generates EL-like images without the need to inject any external power into the PV modules. Its compact, battery-powered design features a 640 × 512-pixel imaging system, powered by a 36 V, 4.4 Ah (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, explained Fuss. These images can be saved to the system’s integrated computer and later downloaded via Wi-Fi.
Optimizing the costing of on-field PV module diagnostics, the latest tool, which does not require rewiring of the PV array or shutting down the inverter, the measurement can be done by a single operator. The Quickcheck can operate for up to 3 hours on a single charge, while its built-in battery needs the same 3 hours for a full recharge.
