Photovoltaic power monitoring: Current sensor chips are used to monitor the output current of solar panels in photovoltaic power systems. This helps to ensure that the PV system is working properly and detects potential faults in a timely manner.
Power optimization: By monitoring the current in real time, current sensor chips can help optimize the power output of a PV system. This maximizes the energy yield and efficiency of the PV system.
Maximum Power Point Tracking (MPPT): Current sensor chips are used in PV inverters in conjunction with MPPT algorithms to help the system track the maximum power point of the PV panels in real time, thus improving the energy conversion efficiency of the PV system.
Safety monitoring: PV systems may experience abnormal currents due to localized shading, dirt, aging of modules, etc. The current sensor chip can be used to monitor and discover these abnormalities in a timely manner to ensure the safe operation of the system.
Data Acquisition and Monitoring: The current sensor chip can collect and transmit the current data generated by the PV system to the data monitoring platform, realizing remote monitoring and analysis of the PV system.
Fault diagnosis: The current sensor chip can help diagnose possible faults or damages in the PV system by monitoring the changes in current, improving maintenance efficiency.
