Freedom and independence: the absence of restriction and the ability to choose, unrestrained by anything else. At ALTEN DC, this has become the foundational principal for every energy solution we develop.We're committed to developing and manufacturing energy solutions that seek to minimize our dependence on fossil fuels and an aging centralized electrical grid, while providing the reliability demanded by the harshest of applications.Located in Bellingham, Washington, ALTEN DC began manufacturing fuel-efficient battery-charging DC generators in 2007. We continue to design and manufacture our DC Generators in the USA, with innovations such the patented NPOD Hybrid Energy system.
