Refined Management tasks, Real-time module level monitoring, and Safety features Boosting energy output and system reliability. They tackle issues like mismatch, soiling, aging, and even "momentary shading". Integrating with the FusionSolar App, the Smart Module Controllers enable installers to remotely monitor the status and performance of each PV module. This simplifies maintenance and troubleshooting by accurately identifying faults through a detailed physical layout of the PV system. If a fault is detected the Automatic Rapid Shutdown at module level kicks in in 2 ms. In emergencies, the whole string drops to 0V in just 30 seconds, protecting O&M personnel and firefighters.

The Smart Module Controller is a DC-DC converter installed on the rear of PV modules in a PV system. Its Module Level Power Electronics (MLPE) nature allows it to manage the maximum power point (MPP) of each PV module to improve the energy yield of the PV system, and performs functions such as module-level shutdown and module-level management. The MLPE also provides refine management in terms of performance monitoring and faults diagnosis. The management system displays the PV module positions, and power. As well as optimizer input and output current and voltage, implementing intelligent module-level monitoring in a friendly-physical layout visualisation. In addition, the PV module layout of the plant can accurately reflect the actual installation positions. The equipment data is uploaded in real time and the status is reported in real time, helping users accurately locate the fault and locate the faulty device. To address safety standards regarding fire protection, Smart Module Controllers allow module level voltage shutdown ensuring maximum safety for installers, maintenance personnel, firefighters, and homeowners alike. MLPE module-level rapid shutdown can be performed within milliseconds when arcing is detected. The RSD function is designed to automatically reduce modules’ voltage to a safe level and de-energize PV wires in case of emergency.
