This adventure begins with a windstorm after which it took crews days to repair the severely damaged power lines. At that time we had been using a pair of old end-of-life batteries rescued from a Cummins diesel pickup truck connected to a conventional marine battery charger as our backup power. We waited all day as our freezer continued operations, powered by these old batteries. Towards dusk, I finally dragged out the generator to power the rest. Surely, there was a better way. That summer, I finally made it a priority to get solar panels installed up on the roof and the batteries upgraded.
