Junction box to protect individual solar panels from overheating

摘要

The box has cooling fins (2) lying outside a metal housing (1). Electronic components such as a protection diode (4) and metal oxide semiconductor field effect transistor (MOSFET), are placed in the housing. The electronic components are pressed against the housing or in a retainer (3) using a spring clip (5), where the retainer corresponds to geometry of the diode and the MOSFET. An electrical insulation made of thermally conductive silicone rubber is provided between the housing and the components.
