General

Intended use

With its "24 hours of sun" vision, Fronius is aiming to offer its customers soluti-
ons for generating, storing, distributing and using energy in an intelligent and
cost efficient manner. The use of surplus energy for hot water preparation con-
stitutes a simple option, with low investment costs, for storing electricity in the
form of heat and using it at a time of the customer's choosing.
The Fronius Ohmpilot, which carries out precisely this task, is therefore an ideal
addition to the Fronius product portfolio in the area of energy management and
a further step towards "24 hours of sun".
Components of The solution as a whole consists of the following components:

Integrating the A Fronius Smart Meter is required to operate the Ohmpilot so that the surplus
Fronius Smart energy can be measured. On the user interface of the inverter, it must be set

whether the Fronius Smart Meter is installed at the feed-in point or in the con-
sumption branch.
Description of The Ohmpilot is a separate device that can control the surplus power from the
the device PV system in a continuously variable manner using pulse width modulation for a
phase between 0 and 100% (or 0 and 3 kW). In addition, the Ohmpilot has 2 ad-
ditional outputs for switching further phases. This means that heating elements
with an output of 300 W to 9 kW can be controlled in a continuously variable
manner.
A heating element with up to 3 kW output can be controlled in a continuously va-
riable manner using one phase.
For a heating element with 9 kW output, the surplus power of 0 - 3 kW is control-
led in a continuously variable manner in phase 1. If even more power is available,
the Ohmpilot also activates phase 2 and phase 1 can again control the surplus in
a continuously variable manner between 3 – 6 kW. If the available power is higher
than 6 kW, the Ohmpilot also activates phase 3 and phase 1 can again control the
surplus in a continuously variable manner between 6 and 9 kW.
