[QUOTE="binky, post: 540779, member: 490"] for inverters, lots, the cooler they stay, the more efficient they are, and more importantly they don't get too hot in summer and shut down. So my preferred location for inverters is an external wall, ideally facing North, but definetly not in the sun. Even today my inverter is running at 30C, I've seen it upto 70C in summer. Inverters cool work by natural convection currents, so you need lots of air movement around them, the vents in that plastic box are not sufficient. It wouldn't be hard to add a few extra, top and bottom of the box, but also bear in mind you want to mount the inverter to a surface that won't melt, and I would be a little worried about the garde of plastic used for that box. Official recommendation is to place something like cement board between the inverter and any wooden boards(flammable surfaces), or you could fashion a metal frame from unistrut to keep the inverter cooling fins away from the plastic itself [/QUOTE]
