Project Fronius Repair #3

The first batch of replacement components arrived and I started replacing a few here and there.

In the process of doing that I removed one of the larger circuit boards and noticed huge black smoke stain on the back. Turns out that one of several APT5010JVR power mosfets died.

On Digikey those go for 36 EUR. On Ebay however you can get them for as cheap as 14 EUR. Well, you do pay with longer shipping time (3 to 4 weeks).

Time to wait again…
