2.5 Environmental protection
ecocoach AG products have an eco-conscious design to ensure they make as little impact on the
environment as possible. The following features come as standard when we design our products:
•ecocoach AG products are made of high-quality materials in an effort to maximise their
service life.
•The product is designed so that the various materials can be separated for reprocessing and
efficient recycling.
•ecocoach AG is always working on product development and reducing its environmental
impact.
ecocoach AG products help users to consume energy more efficiently, which reduces the day-to-
day impact on the environment. ecocoach AG endeavours to keep the impact on people and the
environment low throughout the entire product life cycle and to re-introduce as much material as
possible back into the material cycle.It is important that the user handles all products carefully and
uses them efficiently.
For information on the return and disposal of the products, see "Disposal and recycling" .

3 Product description
3 Product description
This section contains information on the product.
3.1 Overview
The ecocoach AG ecoBatterySystem reliably stores the property's surplus solar energy and enables
all critical energy producers and consumers in the building to be directly regulated. It has been
developed specifically for optimising private consumption in building applications. The energy flows
can be viewed at any time and optimised very easily using the ecocoach App.
The ecoBatterySystem, together with the components described below, forms the heart of the
ecocoach energy storage concept.
Figure 1: Overview of the ecoBatterySystem
ecoBasicControl + ecoCards
The ecoBasicControl includes the ecoFirewall and the PLC control unit with standard ecoCards. In
addition to the 24 V DC supply for all low-voltage components provided by the ecoPowerSupply
and the firewall protection provided by the ecoFirewall, the PLC control unit’s functionalities are
completely centralised. It acts as a central processing unit, coordinates the exchange of data
and control commands between the various connected components and makes all the necessary
calculations.
ecoEnergyMeter
The ecoEnergyMeter measures various parameters associated with the connected components and
sends this information to the ecoEnergyManager. This enables the connected components to be
monitored and managed around the clock.
The following parameters are analysed:
•Power
•Energy

3 Product description
ecoEnergyManagementSystem
The ecoEnergyManagementSystem controls the flows of current between the connected
components. The relevant parameters are defined using the ecoSetupTool. The most important
functions of the ecoEnergyManagementSystem are as follows:
•Managing priorities, e.g. in which sequence should the connected components draw on the
self-generated photovoltaic energy
•Switching components on or off according to their activation thresholds, e.g. switch on the
boiler when the battery is at >90% capacity and surplus mains power is >3 kW
•Overriding components on a user-specific basis, e.g. using a command from the ecocoach App
•Peak load management, e.g. to charge an electric car at full power without prolonging the
connection to the public grid
•Emergency power (in combination with power system protection), e.g. to disconnect the
domestic grid if there is instability in the public grid to ensure that the property’s power supply
is not affected by a power outage.
ecoInvert
The ecoInvert operates at the domestic grid’s power supply level and converts incoming and
outgoing voltages into the necessary target voltage. Incoming alternating current is thus converted
into direct current and vice versa so that the ecoBatteryModule can be charged/discharged.
ecoBatteryModule
The ecoBatteryModule is the lithium battery of the ecoBatterySystem. It stores any surplus energy,
which is used to cover subsequent demand.
Connections
The following energy producers and consumers can be connected (see Production Sheet):
Examples
•Electric boiler
•Domestic grid
•Charging station
•Mains
•Photovoltaic system
•Standard consumer
•Heat pump
