An inverter is pretty heavy duty solid state transisters, doesn't like burning heat followed by 90% humidity & turtle turds & then an ice storm.
I agree unless you get a sealed Outback inverter. From what I understand, they are used by our military over in the sand because they are sealed and deal well with harsh climates.
Good to see someone else who is taking advantage of solar. I was so overwhelmed when I first started but had some really cool people take the time to walk me thru it so I figure I should help some others if I can.
We sort of cheat with our off-grid system because we have a couple gas wells on our property which make our solar requirements minimal. A gravity spring rounds out our off grid system.
