dear subscribers and viewers in this video I am going to repair a china solar based inverter which is 24v.
it was repaired last time but it did not work properly and faulty again very soon.
the fault is related to DC booster section .
all DC booster section MOSFETs are shorted or blasted.
I tested all MOSFETs with multimeter and found all faulty.
replaced all new MOSFETs and also change drive ic of this DC booster section sg3525.
then I replaced all gate resistance 10ohms.
so this is how I successfully repair this inverter section.
hope you will find this video helpful.
