How Does SMA Define Self-consumption and Self-sufficiency?
Self-consumption without storage
Selfconsumption
rate = 30%
Self-consumption with useable storage of 5 kWh
Self-consumption
rate = 60%
Degree of selfsufficiency = 30%
Self-consumption rate
=
Degree of self-sufficiency =
Degree of selfsufficiency = 52%
self-consumed solar energy (AC)/solar energy that can be directly* converted
into AC power
self-consumed solar energy (AC)/power consumption
*directly means without storage on the DC side

Energy Management – Load Profile
> To create a load profile
The Sunny Home Manager determines the
household's typical energy consumption and uses it to
prepare a load profile.
> To control the SMA radio-controlled sockets
The Sunny Home Manager uses this load profile and
the
h energy fforecast to id
identify

bl times
i
to
increase self-consumption. If the SMA radio-controlled
sockets are set to "automatic," the Sunny Home
Manager turns appliances on at these times.
> Energy consumption per SMA radio-controlled
socket
The energy consumption data is saved for each
appliance associated with an SMA radio-controlled
socket.

SUNNY HOME MANAGER
Energy Management – Load Control
Optimization of self-consumption or yield by intelligently adjusting turn-on activation times
of loads.
The load control algorithm operates in two steps:
1) Planning the turn-on times of loads
> Optimization
p
((self-consumption
p
or costs))
> Taking into consideration the secondary conditions, e.g.
> Allowed turn-on time
> Socket status (manual/automatic)
> Minimum duration of any interruption
2) Controlling the loads taking into consideration the control plans

Load Control
Smart Meter with S0 Interface
> The smart meter is the information gateway
between grid operators and consumers and/or
prosumers
> Offers information necessary for load control
> Meters with an S0 interface typically transmit 250
to 10,000 pulses per kilowatt hour and we
recommend a resolution of at least 1,000 pulses
per kilowatt hour
> Bidirectional meters require one S0 interface for
each counting direction
27
Load Control
Smart Meter with D0 Interface
> Among other factors, meters with a D0 interface
vary in their transmission protocols and the
number of decimal places.
> The D0 meter resolution should be at least
10 Wh.
> D0 meters can be extensively programmed
programmed. As
a result, meters which use has been successfully
tested may be incompatible.
> Meters must output accumulated values ‒ an
aggregated total power of all three phases
(cumulative meters)
28
SMA Energy Meter
Universal Data Acquisition for Intelligent Energy Management
> Suitable for universal use regardless of existing
energy meter
> Three-phase, bi-directional measurement

Load Control
How can I tell whether my appliance is supported?
> Turn on the appliance.
> Program and start it.
> Unplug the plug and wait.
> Reinsert the plug.
If the appliance continues to run, it is suitable for load
shifting.
If the appliance does not continue to run, self-consumption
can only be increased with an intermediate storage unit.

SMA radio-controlled socket for program-controlled loads
Preparing the load, using the example of a washing machine:
Switch the SMA radio-controlled socket to "on" using the
touch key or via Sunny Portal.
Load the washing machine with laundry and add detergent.
Switch on the washing machine and select the program
program.
Start the program sequence.
Switch the SMA radio-controlled socket to "automatic" using
the touch key or via Sunny Portal.
At the right time the Sunny Home Manager starts the washing
machine again so that the program can continue to run.

How are the self-consumption rate and degree of self-sufficiency estimated?
Degree of self-sufficiency
Input parameters: Power consumption, PV power und usable battery capacity
Estimate of self-consumption rate and degree of self-sufficiency
104
Power consumption = 5000 kWh/a, PV power = 5000 Wp, usable battery capacity = 0 Wh
Rate of self-consumption = ca. 30 %
Degree of self-sufficiency = ca. 28%
105
Rate of self-consumption = ca. 47 % (+ 57%)
Degree of self-sufficiency = ca. 42% (+ 50%)
106
Rate of self-consumption =
ca. 61 % (+103%)
Degree of self-sufficiency = ca. 52% (+ 85%)
107
What happens with a Battery that has twice the Capacity?
Rate of self-consumption = ca. 69 % (+13%)
Degree of self-sufficiency = ca. 57 % (+10 %)
Batteries that have twice the capacity only provide a marginal increase.
108
What happens with a PV plant that is twice as large?
Rate of self-consumption =
ca. 37 % (- 40%)
Degree of self-sufficiency = ca. 64 % (+23%)
A PV system size that is twice as large increases self-sufficiency, but significantly reduces self-consumption.
