FRONIUS OHMPILOT
Optimising self-consumption through the intelligent,
continuously adjustable regulation of heat sources
NOW COMPATIBLE WITH
FRONIUS ENERGY PACKAGE
The Fronius Ohmpilot is a consumption regulator designed to use excess solar power to heat water. Thanks to the continuously
adjustable regulation from 0 to 9 kW, surplus PV current can be put to highly efficient use and fed to the consumers in the
household.
The Fronius Ohmpilot is primarily used to intelligently control heating elements for providing hot water in boilers and buffer
storage tanks, but can also be used for infrared heating or towel radiators. Solar power can thus provide a family home with
average levels of water consumption with most of their hot water from September to March. The result is maximum selfconsumption, a reduction in the household’s CO2 emissions and less wear on the building’s main heating system during the
summer months.

Installing the Fronius Ohmpilot could not be easier thanks to straightforward commissioning via the dedicated website as well as
a simple communication connection via WLAN. The Fronius Ohmpilot also protects the grid by cleanly and reliably activating the
consumers, leaving you as the installer fully equipped for the demands of today and tomorrow.
The Fronius Ohmpilot is compatible with all Fronius inverters. A Fronius Datamanager 2.0 and a Fronius Smart Meter are required
to use the device. The Fronius Datamanager is integrated as standard in Fronius Symo, Fronius Symo Hybrid, Fronius Primo,
Fronius Galvo and Fronius Eco inverters. The Fronius Datamanager and the Fronius Smart Meter can be retrofitted in existing
inverters at any time.
