Quick Reference Guide
Rev.0001
This document is valid for the Sunny Home Manager 2.0* ( HM-20) from firmware
version 2.00.00.R.
Only qualified persons with the following skills are allowed to perform the tasks described in this document:
• Training in the installation and commissioning of electrical devices and i nstalla-
tions
• Training in how to deal with the dangers and risks associated with installing and
using electrical devices and installations
• Knowledge of the applicable standards and directives
• Knowledge of and compliance with this document and all safety information
The Sunny Home Manager 2.0 is the central device responsible for energy management in households with a PV system for self-consumption.
The Sunny Home Manager 2.0 carries out the following basic tasks:
• Collection of energy- and power measured values in the interconnected household
• Energy monitoring: Presentation of energy flows via Sunny Portal
• Energy management: Automatic control of interconnected household loads wit h
the aim of energy efficiency optimization
• Dynamic limiting of the active power feed-in
• Active power measurement via integrated measuring unit with direct connection
up to 63 A limiting current
• Use of current transformers necessary for applications above 63A
• Interconnection of loads via EEBus and SEMP
• Support of the WLAN smart plugs Edimax SP-2101W
The Sunny Home Manager 2.0 does not support S0- or D0 energy meters, Plugwise products or Miele@home devices. The Sunny Home Manager 2.0 is not
equipped with a Bluetooth interface. The Sunny Home Manager 2.0 is not an en ergy meter for power consumption in the sense of the EU directive 2004/22/EG
(MID). The SunnyHomeManager 2.0 may not be used for billing purposes. The
data collected by the Sunny Home Manager 2.0 relating to the power generated
by your PV system may deviate from the data of the main energy meter, which is
used for billing purposes.
The Sunny Home Manager 2.0 may only be connected to the subdistribution of the
household on the load side behind the energy meter of the electric utility company.
The Sunny Home Manager 2.0 must be installed in a switch cabinet.
It is possible to use the Sunny Home Manager 2.0 in delta IT grids. When using the
Sunny Home Manager2.0 in delta IT grids, the cumulative power values are correctly measured. Due to the measuring principle of the Sunny Home Manager 2.0,
other measured values may be incorrect.

SAFETY INFORMATION
DANGER
Danger to life due to electric shock
Lethal voltages are present in the live components.
• Disconnect the connection point from voltage sources and make sure it
cannot be reconnected.
• Before performing any work on the SunnyHome Manager 2.0, disconnect the grid side from all voltage sources using an install ed disconnect
switch.
• Ensure that the conductors to be connected are de-energized.
• On ly us e the S unny Hom e Ma nage r 2. 0 in a dry e nvir onme nt an d kee p
it away from moisture.
• Instal l the Sunny Home Man ager 2.0 in the switch c abinet only and ensure that the connection areas for the line conductors and the neutral
conductor are behind a cover or have contact protection.
• Disconnect the Sunny Home Manager 2.0 from voltage sources before
cleaning. The Energy Meter must be cleaned with a dry cloth only.
• Observe the prescribed minimum clearance between the network cable
and live installation components, or use suitable insulation.
DANGER
Danger to life due to electric shock if external disconnect switch is
missing
Lethal voltages are present in the live components of the
Sunny Home Manager 2.0.
•Install an external disconnect switch between the
Sunny Home Manager 2.0 and the grid-connection point. The external
disconnect switch must be close to the Sunny Home Manager 2.0 and
easily accessible.
WARNING
Danger to life due to electric shock
Overvoltages (e. g. in the case of a flash of lightning) can be further conducted into the building and to other c onnected devices in the same network via the network cable if there is no overvoltage protection.
• Ensu re that all de vices i n the sa me netw ork are integr ated in the existing
overvoltage protection.
• When laying the network cable outdoors, attention must be given to suitable overvoltage protection at the network cable transition outdoors to
the network inside the building.
WARNING
Risk of fire due to dirty or oxidized contact surfaces of live aluminum conductors
Connecting dirty or oxidized contact surfaces with aluminum conductors reduces the ampacity of the live terminals, thereby increasing the transition resistances. This can cause components to overheat and catch fire.
• The contact surfaces are to be cleaned, brushed, and treated with acidic
and alkaline substances (e.g. petroleum jelly or special thermal grease).
WARNING
Fire risk
If a fuse is mi ssin g or in corr ect a nd a f ault occu rs, a fire may be caused. This
can result in death or serious injury.
• Fuse the Sunny Home Manager 2.0 line conductor with a fuse or a selective circuit breaker with max. 63 A.

Installation when not using the integrated measuring unit
If an SMA Energy Meter is installed at the grid-connection point and is not to be
replaced by the Sunny Home Manager 2.0, the Sunny Home Manager 2.0 can
also be operated without the measuring unit being enabled.
1. Connect the line conductor L1 and the neutral conductor to the voltage supply
of the Sunny Home Manager 2.0.
2. Select the SMA Energy Meter present as the purchased-electricity and feed-in
meter in Sunny Portal (see Section "Defining the Energy Meter at the Grid-Connection Point").
Measuring the PV production power (single-phase / three-phase) up to
63 A
In PV systems with inverters from other manufacturers or hybrid systems with SMA
inverters, the integrated measuring unit can also be used for measuring the PV production power. In this case there must already be an SMA Energy Meter installed
at the grid-connection point (see "Installation when not using the integrated measuring unit").
1. Connect the Sunny Home Manager 2.0 to the common connection point of all
inverters in the household grid.
2. Select the Sunny Home Manager 2.0 as the PV production meter in Sunny Portal (see Section "Defining the Energy Meter at the Grid-Connection Point").

NETWORK CONNECTION
Connecting Sunny Home Manager 2.0 via router / network switch
The Sunny Home Manager must be connected to the local network via a router / network switch. If the Sunny Home Manager 2.0 is connected directly to
an SMA inverter via network cable, the data will not be transmitted to the rou ter.
IGMP protocol from version 2 must be supported
Data transmission with the Sunny Home Manager2.0 works with multicasts.
In order for the Sunny Home Manager 2.0 to function correctly, all used network components (router, network switch, power-line communication and
WLAN converter) must support at least IGMP protocol version 2 (IGMP V2)
(see manufacturer documentation).
