Use and maintenance of mppt regulator

(Summary description)The mppt regulator is generally not allowed to remove the cover during use.

Information

The mppt regulator is generally not allowed to remove the cover during use. Normally, a comprehensive inspection and maintenance is carried out every 200 hours or so, and the contents are as follows:

1. Remove the protective shell and check whether there is any dirt and burning on the contact surface. If there is dirt, wipe the contact surface with a clean paper. If the contact is ablated or the plane is uneven, resulting in poor contact, generally use "00" sandpaper or sand strips to smooth it, and finally wipe it with clean paper.

2. Check the firmness of each joint, measure the resistance and the resistance value of each coil. If it is damaged, it should be repaired or replaced with a new one in time.

3. Check the closing voltage and reverse current of the cutout, the limit voltage of the voltage saver, the limit current of the limiter, and the gaps and air gaps of various contacts. If it does not meet the requirements, it should be adjusted.

4. Check the adjusted mppt regulator, and pay attention to the indication of the charging ammeter pointer when starting the diesel engine. If the pointer of the ammeter still points to the "-" side when the diesel engine is running at a speed above the middle level, it means that the contact of the circuit breaker is not disconnected, and the grounding switch should be disconnected quickly; otherwise, the battery, mppt regulator and charging generator will be damaged. . If the pointer of the ammeter still points to "0" after the diesel engine is started to the rated speed, the adjustment described is not adjusted according to the technical requirements, and it should be checked and adjusted again.
