Anyone installed a wall, heat extraction fan and thermostat for solar inverter and battery room?

If so, details of fan and thermostat please.

I just run the aircon for the batteries and inverter, taking the load past the hottest time of the day.

Inverter aircons are cheap now, and if you have excess energy, why not use it to prolong the lifespan of your equipment for your solar system?

And if you have a temperature-controlled room, you also have a place to store things that are sensitive to extreme heat changes. It also helps with humidity.

My solar room has aircon running 24/7.

It’s a multi-purpose room, solar kit, computer servers and wine cellar.

Thanks.

I was thinking about installing an aircon but changed my mind to extraction fan.

I've never had a high temperature alarm and realise that the inverter build is a big heatsink, so I will try to just extract that heat outside the room.

I'm working on a no air conditioner passive cooling system.

Passive cooling of houses involves creating an upward draft through something called a "cupola"

You can do your own research. It doesn't cost very much and no fan is needed.

Look up online the guy who went to an Amish house in Pennsylvania in August which is typically the hottest most humid time of year and noticed in the Amish house he was visiting there was no ac or fans (they don't like electricity except out in their workshop) and the house was amazing cool and comfortable.

Good luck 🤞

The problem with the cupola effect is that it helps more with comfort than real cooling. For a house, that can be enough. Air movement, shade, and draft make people feel cooler.

But batteries and inverters under load need real heat removed, preferably before the heat builds up. Passive cooling can help, but in tropical heat, under serious load, I would not rely on it alone.

I am completely with you about removing moisture and creating a cooler feeling. It is a great invention, and people have used this kind of passive cooling for thousands of years. Still it is not especially good for dust and pollution from outside, if that is a problem in the area.
