With 40 C + summer, i have been keeping eye on the temperature of my 6kw deye hybrid and noticed that it has been hitting 90 C + everyday at peak generation.
I wanted to help the inverter with the cooling a bit, so i decided to add this fan unit which claims its peak rpm is 5000.
Attaching some pics below. The fan came with a regulator to adjust rpm but i installed it straight without the regulator so that it can run at full speed. After monitoring for a couple of days, i plan add a smart switch and automation for it to be powered only when the inverter temperature hits a certain value. and turn of when it has cooled down enough so that i can extend the life of the fan. Its like 1500 INR and they claim 60000 hrs runtime on the product, so we'll see.
As you can see, i just left it sitting on top of the heatsink and it is blowing air into the heatsink.
As seen in the temperature graphs, the fans were able to bring down the temp my almost 20 C within a short period. Graph showing temperature of yesterday and i installed the fans mid afternoon today when the temperature starts dropping steeply.
I will also see how it performs if i put it upside down in which case it will suck air from below instead of blowing and note if it is better that way.
installing it at the botton will need making a custom mount etc, and i don't feel like putting in so much effort as of now if this works.
