I take it your batteries are in the inverter room - cool (literally). Our batteries are outside, in a Rubbermaid deck box and mostly in the shade. This time of the season the lid is propped open 6". We have a crawl space where all the stuff is but obviously not the batteries. Humidity isn't a problem and the space is great for the cooling. And another reason I don't want to go Lithium is I will have to get the dang things down there through a trap door and dragged into place. And rewire. And more and more. So much is of system design but it's usually the components themselves. Dang I don't want to get either the VFX or FM off the mounting surface with 4.5' of head space. It was no problem at the time of installation.fcwlp wrote: ↑Sun Jun 28, 2020 12:50 pmYour temps are very similar to what we have at 5,500' in AZ. We may break 100 one or two days a year in June (not this year) but nights are typically in the 60s. I finally put a mini-split in, more for heat, but my wife likes the cooler temps during the day.
On my own inverter building, I have put an exhaust fan with a differential thermostat. It is currently set that if the inverter room is >75F and the outside air temp is at least 5 degrees cooler the exhaust fan runs.
Yup, the day of installation is no problem. What about in 15 years?
