Biographies
Carlos Restrepo (carlos@sonnen-batterie.com) received his
bachelor's and master's degrees in electrical engineering
from Georgia Tech in 1998 and 2000, respectively. He has
spent 14 years in the electrical products industry focusing on
the development of new technologies associated with power
conversion, circuit protection, energy management, and
safety. He worked in the development of arc fault detection
technology for eight years in Siemens. He was a senior engineering manager at Eaton responsible for the development
of smart lighting control systems, circuit, and people protection devices. At SolarMax, he was the vice president (VP) of
research and development (R&D) responsible for running
U.S. R&D operations centered on the creation of string and
central photovoltaic inverters for the U.S. market. Currently,

he is the VP for R&D for Sonnenbatterie in the United States
and is responsible for the development of the next generation of smart energy-storage systems.
Andres Salazar (andres@sonnen-batterie.com) received
his bachelor's degree in electronic engineering from Universidad del Norte, Barranquilla, Colombia, in 2005 and his
M.S. degree from the University of Puerto Rico, Mayaguez
campus, in 2011. His interest in renewable energy and
solar power generation has led him to participate in different publications in power electronics and education conferences such as the IEEE Applied Power Electronic Conference, the IEEE Frontiers in Education Conference, and the
Virginia Tech CPES Power Electronic Conference. He is currently working in the research and development team of
Sonnenbatterie, where he is developing novel lithium iron
phosphate storage systems for residential and commercial applications.
Hermann Schweizer (h.schweizer@sonnenbatterie.de)
received his Dipl.Ing. (FH) from the Hochschule Augsburg
in 1993. He worked for development and innovation within Osram for more than seven years and received the
company innovation prize for the contribution to a novel
mercury free flat lamp light source in 1999. He was with
Helbling Technik, where he lead a research and development team in the field of power electronics and developed
various products mainly in the field of small and midsized
power supplies as well as frequency converters. He was
also a general manager at Bavaria Digital Technik. Currently, he is chief technology officer at Sonnenbatterie,
leading the development of the next generation of gridtied battery storage. He is a Member of the IEEE.
Antonio Ginart (antonio@sonnen-batterie.com) received
his B.Sc. and M.Sc. degrees in electrical engineering from
Simon Bolivar University in 1986 and 1991, respectively,
and his Ph.D. degree from Georgia Tech in 2001. He served
as a faculty member at Simon Bolivar University for more
than ten years. He was principal and founder of Intelligent
Automation Systems, later acquired by Impact Technologies, where he became senior lead engineer developing
dynamic degradation models and methods for power
devices as well as fault-tolerant techniques for extended
operation of power controllers in modern power systems.
He was lead research and development engineer in charge
of developing solar inverters aimed at delivering reliable
and economical solar energy to the smart grid at SolarMax. Currently, he is a principal engineer at Sonnenbatterie, where he is developing the next generation of grid-tied
battery storage systems. He also has acted as principal
investigator on several NASA/Department of Defense SBIR
grants. His research has led to more than 70 publications
and patents. He is a Senior Member of the IEEE and an
affiliate faculty member in the College of Engineering at
the University of Georgia.
