Note:

The MPPT controller must be mounted on an iron or metal support to prevent machine vibration due to instability. The MPPT controller should have some clearance around its casing. The input and output wires should be as short as possible to avoid excessive power dissipation during transmission. There is high voltage and high current in the machine, and non-professionals are not permitted to disassemble it. The input and output terminals must be secure and not loose to prevent overheating at the connection point.
