Off-Grid Origins Residential power systems – particularly the inverters that provide more popular Alternating Current (AC) voltages, standards and connections – are a far cry from their primitive ancestors of only a few decades ago, when hobbyists and off-grid home or cabin owners needed a fair amount of electrical expertise, as well as tolerance for not-quite-ready-for-mainstream technology and performance. Increased world-wide demand, dramatic improvements in the semiconductor and microprocessor industries, economies of scale, improved safety standards, regulations, plus diligent and competitive engineering have all contributed to the superb home inverter offerings available today. From it’s infancy as an inferior, pioneering …
