Solar is great, got some on our stick house. Lots of nice snow here, still coming down. Grid went down about 5 am (clocks stopped). Our battery backup kicked on via Xantrex Inverter. Wife is on O2 24x7 and we both use CPAP machines. Everything just kept running fine, above plus fridge, freezer, and boiler. We have several battery banks, and only small 200 AH (at 48 volts) was connected. It was still doing fine at 4 pm when grid power returned, never had to switch in our bigger bank.
Now if the sun would melt about 18" of snow off my collectors ....
