FRONIUS ENERGY
MANAGEMENT SOLUTION
with Fronius inverter and Smart Meter
With the inverter-integrated energy management from
Fronius, energy-intensive loads in the household can be
directly controlled with surplus PV energy. Thanks to the
open interfaces, a variety of third-party components can
be integrated in the PV system.
4 DIGITAL ENERGY MANAGEMENT OUTPUTS
With the digital energy management outputs, an external relay can be
controlled by the inverter. This relay switches on the load as soon as the
defined surplus energy threshold is reached. Furthermore, it is possible
to define a minimum load runtime or set a load prioritisation.

OTHER OPEN INTERFACES
With the open interfaces Modbus RTU, Modbus TCP SunSpec, LAN/
Wifi and Fronius Solar API (JSON), third-party components such as a
wallbox or a home automation system can be intelligently controlled
with surplus PV energy.

TS 100A-1; TS 65A-3; TS 5KA-3
A data communication cable (CAT 5 or higher) is required for cabling the digital outputs. This is used
to control an external 12V relay.
Please take the maximum switching capacity of the data communication unit into account when
selecting the 12V relay:
SnapINverter series (Datamanager): 3,2 W
GEN24 Plus: 6 W
We recommend, for example, a FINDER relay of type 39.11.0.012.00060
The detailed load management settings on the Inverter Web
Interface (surplus thresholds, minimum runtimes, load priori
tisation) can be found in the whitepaper „Energy flow management using the four digital outputs“:
Cable connection (CAT5 or higher) via Modbus RTU (RS485)
/ Suitable for single-phase and three-phase grids
/ Measures energy consumption and energy
from the grid

THREE BUSINESS UNITS, ONE GOAL:
TO SET THE STANDARD THROUGH
TECHNOLOGICAL ADVANCEMENT.
What began in 1945 as a one-man operation now sets technological standards in the fields
of welding technology, photovoltaics and battery charging. Today, the company has around
5,660 employees worldwide and 1,321 patents for product development show the innova-
tive spirit within the company. Sustainable development means for us to implement
environmentally relevant and social aspects equally with economic factors. Our goal has
remained constant throughout: to be the innovation leader.
PERFECT WELDING
Our mission is Perfect Welding; a task
we have approached with passion and
skill for decades in order that our customers can join materials with the perfect weld seam. With our outstanding
technologies and services and together
with our customer‘s applications, not
only do we solve their specific welding
technology problems, but we also make
a substantial contribution to increasing
their productivity.
Further information about all Fronius products and our global sales partners and representatives can be found at www.fronius.com
SOLAR ENERGY
Our mission is to achieve 24 hours of
sun. Day after day we are hard at work
turning this vision of a future in which
100% of the world‘s energy needs are
covered by renewable sources into a
reality. We are therefore concentrating
on solutions to intelligently, efficiently
and economically generate, store, distribute and consume solar energy.
PERFECT CHARGING
As know-how leaders in the world of
battery charging, we deliver exceptional solutions to create the maximum
benefit for our customers. For the
intralogistics sector, we are committed
to energy flow optimisation for electric
forklift trucks and are constantly striving for the next innovation. Our powerful charging systems for vehicle workshops guarantee safe and reliable
processes.
