Intersolar: Ohmpilot of Fronius increases solar self-consumption
To successfully implement our vision of 24 hours of sun, we must use synergies,” explains Martin Hackl, head of the Solar Energy Division. There is enormous potential for the efficient use of renewable energy sources in combining electricity, heat and mobility. The new Fronius Ohmpilot allows private operators of photovoltaic systems to significantly improve their self-consumption and save on costs.
Intelligent use of solar excess energy
The intelligent energy management solution uses excess energy to supply consumers such as heating elements, infrared heaters or other heat sources without motors with the currently available excess and to organise the operation of heat sources, for example heat pumps. This is made possible by the continuously adjustable regulation from almost zero to nine kilowatts. The device has a weight of around three kilograms and can be easily installed. Net wholesale sales price will be probably roughly over 1,000 Euros, Hackl told pv Europe. As a next step the company is working to make the Ohmpilot compatible with the Fronius Energy package with battery storage. This way the proportion of self-consumption can be even increased, Fronius Technical Sales Manager Simon Noringbauer explains.
Fronius Energy Package
The Fronius Energy Package consists of inverter, battery and the bi-directional Fronius Smart Meter, which clearly displays energy usage in Fronius Solar Web. To remain autonomous during consumption peaks or in winter when there are very few solar hours, users can add an Ökofen pellet stove to the Fronius package. With its integrated Stirling generator, this provides the additional energy required. In this way, private operators have the option of supplying their household almost exclusively with self-generated solar and pellet power. (HCN)
