The past two winters I have relied on the battery box I first built as a template for most of my construction techniques since. In addition, I have packed the batteries in extra closed cell foam, and then last year in two surplus picnic coolers donated by Mummu and Grandpa.
With the porch on the cabin this year, I intend to have them out on the porch for the winter. But still, they must have some protection.
Now that the box is complete and ready for the batteries, I have decided to also upgrade our inverter from the Mastercraft 3000W we have been using since the beginning of our endeavour here. Watch for the changeover in my upcoming posts.
