Hello bro´s,
I´m repairing the MPPT board of the growatt SPF5000ES. The buck diode APT30DQ60BG has blown up this one is fitted next to 2 FGH60N60UFD these look good from the outside. My question should I replace them also I measered while it´s mounted and don´t know if this is the right way to dismount them is a bit hard job while no soldertool gets the tin melted.
I attached some pics.
Would love to get some advice on this.
Thanks,
Rudy
