Evolution of our off-grid system

ElectronicsAndSwitchingSince we started in November 2009, our off-grid installation has progressed in a number of steps.

Nov 2009:  Generator only
May 2010:  Add batteries and inverter/charger
May 2011:  Add solar panels
Oct 2011:  Add thermal store
May 2012:  Add load controller
May 2013:  Add proportional controller
May 2014:  Add monitoring and optimization

I’ll blog about these steps one at a time, starting with the generator.
