Aurora Solar Inverter 80mm Fan Cowling

thingiverse

These parts allow for an additional 80mm fan to enhance the cooling of the heatsink on a Aurora Solar Inverter. For my installation I have used a 12V Fan driven off its own 5W Solar Panel (with a simple 7812 Voltage regulator & heatsink) as it only needs to run when the sun is out. It is reducing the Inverter temperature by about 8 degrees which hopefully will increase the longevity of the inverter. The Fan direction is to suck the air upwards.
