Instructions for integrating
AC•THOR® or AC ELWA® -E into SMA Sunny Home Manager (SHM) or SMA Energy
Meter
Default settings on AC•THOR or AC ELWA-E
Before commissioning, it is essential that you read the assembly instructions
that accompany the device, as well as the operating instructions available on
line.
Find the AC•THOR operation manual here.
Find the AC ELWA-E operation manual here.
Two control types are available for SMA:
SMA Home Manager| The power signal which the SMA Sunny Home Manager gives the
my-PV device depends not only on the feed-in, but also on the superordinate
energy planning that can be configured in the SMA Portal. In this control
mode, the SMA Home Manager decides when the my-PV device outputs power.
NOTE: There are no records of grid consumption and grid feed-in in the
my-PV Cloud.
---|---
SMA Direct meter communication| This control type can be used with the signal
sources SMA Energy Meter and SMA Sunny Home Manager.
In contrast to the “SMA Home Manager” control type, the my-PV device itself
takes over the function of the controller, as the surplus information is read
directly from the SMA meter. The power control is carried out much faster than
with the “SMA Home Manager” control type.
NOTE: The my-PV device is not listed in the load overview in the Sunny
Portal.
This control type is available for the AC•THOR from firmware version a0020202,
for the AC ELWA-E from firmware version 201.00!
NOTE for AC•THOR: To install this firmware on already delivered devices,
please send us the 16-digit serial number to support@my-pv.com. We will gladly
activate the update for you!
AC•THOR Control setting for “SMA Home Manager”
With the AC•THOR, “SMA Home Manager” must be selected either on the display or
in the web interface for the control type. Further settings are not required
for communication with SMA.
TIP for optimized use of the AC•THOR by the Home Manager.
If a heating element <3kW is connected to the AC-THOR, or if a heating element
<9kW is connected to the AC-THOR 9s, then set the rated power of the heating
element using this URL command on the AC•THOR:
IP-Adress xxx.xxx.xxx.xxx/setup.jsn?shmmaxpower=6000
(Example for a 6kW heating rod at the AC•THOR 9s)
You can check the correctness of the parameter entry in Sunnyportal. The value
“Power consumption:” 9000 W must be changed to the entered value after a few
minutes.
AC ELWA-E Control setting for “SMA Home Manager”
With the AC ELWA-E, “SMA Home Manager” must be selected for the control type
in the web interface. Further settings are not required for communication with
SMA.
TIP: If the Sunny Home Manager does not find the device immediately, a
restart after saving the control type could help!
AC•THOR / AC ELWA-E Control setting for “SMA Direct meter communication”
This control is suitable for both the SMA Sunny Home Manager and the SMA
Energy Meter! For both AC•THOR and AC ELWA-E, “SMA Direct meter communication”
must be selected in the web interface for the control type. Further settings
are not required for communication with SMA.
If this type of control is used in combination with a storage battery, we
recommend setting the “Control target” to “-200” Watt!
Select “SMA Direct meter communication Auto” if there is only one meter.
Select “SMA Direct meter communication Manual” if there are multiple meters on
the network and a specific one of them is to be selected as the control source
by specifying its IP address.
TIP: The control settings can only be adjusted if the my-PV device has
the factory preset device number “1”. Even if several devices are controlled
by „SMA Home Manager“, it is not necessary to change the device numbers! See
heading “Basic settings” also on the “Setup” page.
Integrating the device in the Sunny Portal for control type “SMA Home
Manager”
The SHM must already be registered in the SMA portal!
If – Configuration – Device overview is selected in the SMA portal, only the
SHM will be displayed at first. AC•THOR or AC ELWA-E will not appear to start
with. Once the configuration process is complete, it will appear in the lower-
level menu item – Load overview and planning.
Searching for and adding AC•THOR or AC ELWA-E in the SHM
Update the list under – Configuration – Device overview – Overview of New
Devices – “Refresh devices”.
This process may take several minutes.
Admin rights are required for this setting!
AC•THOR or AC ELWA-E will appear as a “Smart Appliance” together with its MAC- address – click “+” to configure.
Configuration – Step 1
Product type will be used automatically in combination with the last three
characters of the MAC address as a device name. The MAC address can also be
seen on the type plate.
Configuration – Step 2
In order for AC•THOR or AC ELWA-E to simply make use of surplus energy that
can no longer be used by other loads, my-PV recommends the following settings:
- Set the priority of the load to a very low
- Switch on the load depending on the proportion of PV energy
- Move the “Optional energy demand” slide as required
Configuration – Step 3
These settings are displayed once more for checking.
Click the “Finish” button to complete the addition of the new system extension. This is confirmed with a message.
Once the configuration is complete, AC•THOR or AC ELWA-E will appear in the menu item – Load overview and planning.
The load characteristics of the new “Smart Appliance” can be displayed again
at any time.
AC•THOR® or AC ELWA® -E Integration into SMA SHM or SMA EM, 230310
In the SHM AC•THOR or AC ELWA-E are not managed via time windows as is usually
the case with wireless sockets for example!
Periods in which hot water securing must be boosted are specified in AC•THOR
or AC ELWA-E settings directly. (see respective operating instructions on www
.my-pv.com)
Bear in mind the optimization target settings within the SHM!
The factory setting of the SHM for the payment settings has an optimisation
target of “economical”.
In this case, my-PV recommends changing the optimisation target to
“ecological”! Readjust this under – Configuration – PV system properties –
Parameters.
Optimization Target
The optimization target indicates whether the Sunny Home Manager should
prioritize ecological or economical factors for load management. If you select
‘ecological- as the optimization target, the Sumy Home Manager calculates the
solution which uses the greatest self-consumption. Greater self-consumption
conserves the environment because there no energy loss caused by the transport
of current through the power chstrbution grid. If you select the ‘economical’
optimization target, the Sunny Home Manager calculates the most financially
rewarding control of the loads, talthg into consideration the feed-in and self
consumption tariffs. In tertian cases, it may be more economical to feed the
pry electridty nto the power distrbution grid and to operate the incivickal
loads at night using electricity pirchased from the grid.
AC•THOR or AC ELWA-E with SHM and battery
my-PV recommends prioritising the use of excess energy for charging the
battery. Only once the battery has finished charging AC•THOR or AC ELWA-E
should start generating heat. This is achieved by making the following
setting:
- Activate “Storage management via the Home Manager”
- Activate “Charging of the battery prior to optional loads”
Once the battery is fully charged, AC•THOR or AC ELWA-E are only then used
when no other consumer has a higher priority!
If the excess PV power is greater than the maximum charging capacity of the
battery, generation of heat can simultaneously happen with battery charge!
Control multiple devices with the SHM
The adaptation of the internal multi-settings for the operation of several
devices is not required when the control type is “SMA Home Manager”!
Since the control type “SMA Home Manager” actively controls loads like AC•THOR
or AC ELWA-E, it is not necessary to configure one device as master and the
others as slaves. All devices continue to have the factory pre-set device
number 1.
Settings for systems with zero feed-in
For systems with zero export to the power-grid the settings have to be made as
follows.
