Ferroamp develops power electronics for renewable energy, photovoltaics and energy storage. The company stands out in particular their bidirectional inverter, power leveling functionality and their modular DC Nano Grid concept. This is similar in many parts to Netpowers proposed Edison network. They would therefore like to see solutions based on voltage networks, and hybrid solutions linked to both AC and DC components. There they can deliver bi-directional AC / DC inverters, bidirectional DC / DC converters for battery, DC / DC converters for solar cells, Li-ion battery modules.
