Hi. Just trying to understand a concept here. I understand that ambient temperature will effect the output of my inverter. It seems that at 35° the power of my phoenix 3000va will drop from 2400w to about 2200w. My doubt is, am I using the same amount of dc power to produce less ac in this example or is it just that everything is being decreased at the same rate due to the heat.
Thanks in advance

No, the inverter output decreases so you can power lower loads, the battery will continue to supply what the inverter needs up to it’s reduced output limit.
Temp affects everything one way or another, whether it be performance, capacity or lifespan.
Thanks. The equipment is all housed in a big outside shed and it can get very hot. I installed a cerbo to control and monitor over the winter and now that it is getting hotter I’ve seen battery temps going up to 38°c. I’m contemplating getting air con in there to run as a dump load. Product longevity might be a help to persuade my other half…
Good call.
Those temps will not be kind to the battery either, and that can get expensive later in life.
An extractor fan and filtered inlet can also make a difference.
My personal system sits in my garage and in summer heatwaves it can get warm. Just leaving the door open a crack and the interior door open, creates enough airflow to knock a couple of degrees off.
Most I have peaked at is 35C and I would not want to repeat that for extended periods.
My battery manufacturer recently updated warranty terms to state it is void if the battery records 40C.
