Сгорел солнечный контроллер Demuda KDY 30A 48В

My Demuda KDY 30A 48V PWM controller burned out after three years of operation. It stopped limiting the output current, regardless of the voltage setting. I'll disassemble it and show you what's inside. This is some kind of defect that was repaired unprofessionally. The transistors were soldered by hand and sloppily.
