Solar pump controller getting too hot

Solar pump controllers operating in very hot climates tend to overheat. Water/Oil cooling seems to work well and allow them to run at full power.

Brilliant idea, well done. I have the 100A Microcare MPPT for my solar and it gets very hot when pushing 90+ amps. I’m going to try something like you’ve done here to cool it.

Go for it!
