Schaefer’s diverse product line offers a variety of solutions for industrial and military alternative,renewable energy designs that utilize these renewable energy sources to create a common bus. Our unique design and manufacturing processes enable the flexibility of conversion from input to output over a wide range of, and easily support, custom solutions requiring thousands of AC or DC volts.

From our Active Harmonic Filters (reducing harmonics, rebuilding distorted three phase currents, correcting Power Factor, and balancing 3 phase currents), Energy Storage Systems, to our PowerStack Series @ 97% Efficiency (400Kw to 10MW+) our robust designs ensure long-life reliable operation in even the most demanding conditions; including condensing applications, as well as ships and military.
