Electric power for the various systems I wanted on Seeker was mistakenly high on my list of things to acquire when we decided to build. I soon learned that it rightly deserves a place at the bottom of the list. The technology is constantly improving and the prices for existing technology is constantly falling. If you are patient, you will either own the best available technology or used equipment at a great value. Or as in our case become the beneficiaries of generosity from someone like Ron Buttke of Wisconsin who donated a literal ton of off-grid power equipment. So now we need to learn everything we can about nickel iron batteries, inverters, charge controllers, and sundries.
