(northern MN) I have yet to see an inverter that can be placed in locations like this and not exceed the warranty temp extremes. <br>> <br>> Enphase has a cold temp acceptability of -40F last time I checked, and when I called they told me about an install in Antarctica using micros. <br>> <br>> I have installed inverters outside in the twin cities, not up here. <br>> <br>> What do you think about this problem?<br>> <br>> Thanks as always,<br>> <br>> Jesse<br>> <br>> Sent from my iPhone<br>>
