The rapid industrial growth in solar energy is gaining increasing interest in renewable power from smart grids and plants. Anomaly detection in photovoltaic (PV) systems is a demanding task.
This procedure describes how to replace the external fan of the Three Phase Inverter. Ensure the AC is turned OFF before removing the fan. Failure to do so may result in damage to or failure of the unit.
For the inverter, once the external cooling fan fails (the fan is blocked and does not rotate, or an animal bites the power supply cable), this in turn causes poor heat dissipation of the
If the inverter already has the new 12-pin cable attached, re-connect the 4-pin and 8-pin power cable connectors to their respective power sockets on the new External Fans assembly. Make sure you
Once the fan stops rotating, the internal temperature of the inverter rapidly exceeds the safety threshold, triggering overheat protection and causing a significant drop in power...
If you observe that a fan-cooled inverter has its fan stuck by objects or the fan blades are covered in dust, the cooling efficiency will be reduced or
Inverter cooling fans run when the inverter is charging a battery or loading appliances, and if there is insufficient power the fan will stop working. Cleaning the fan, increasing battery power or tightening
If you observe that a fan-cooled inverter has its fan stuck by objects or the fan blades are covered in dust, the cooling efficiency will be reduced or may even fail completely.
To solve this problem, it is first necessary to ensure that the inverter installation site is ventilated to prevent the inverter from being exposed to the sun. For the abnormal problem of the
