AC•THOR®/ AC•THOR®9s Operating instructions, version a0020806 4
Before placing into operation it is essential to read the assembly instructions provided with the
device.
Commissioning takes place in a few steps and must be carried out when the AC•THOR is started for
the first time or after resetting to factory settings.
Use the left and right arrow keys to see more options.
From firmware version a0020202 onwards, French or Spanish can be selected in addition to German
and English.
See chapter headed "Operating modes".
The selection can also be changed at a later date.
Use the left and right arrow keys to see more options.
Besides the my-PV Meter and open communication protocols such as http, Modbus TCP, Adjustable
Modbus RTU and Adjustable Modbus TCP, as well as frequency control, pre-set signal sources are
available for many compatible manufacturers.
For certain compatible partners the choice between „Auto“ (automatic IP-search of the device) or
„Manual“ (manual entry of the IP address of the source) is possible. If a control type with the
addition "Manual" is selected, the next step is to set the IP address of the signal source.
In the case of a control mode with the addition "Manual", the IP address of the signal source
must not change during operation (e.g. by a DHCP router), otherwise the AC•THOR will lose the
control signal.

When controlling via Modbus RTU, the operating mode M7 cannot be used!
If the Huawei Smart Dongle is used on the inverter, communication
problems may occur with this type of connection. We therefore recommend
using the control type "Huawei (Modbus TCP) Manual" if possible, especially
if a battery storage unit is present!

Works with Huawei devices that communicate via Modbus TCP, such as the
Huawei Smart Dongle-WLAN-FE!
Note: From dongle firmware SPC124, TCP must be activated locally via the
Huawei app!
Alternatively, the AC•THOR could also be controlled via Modbus RTU. If a
battery storage is available, however, the "Huawei (Modbus TCP) Manual"
must be used explicitly!

This control type is available for the SMA Energy Meter and SMA Sunny
Home Manager devices.
If this control type is carried out by the Sunny Home Manager, the
superordinate energy planning for the my-PV device is then not given. There
is also no visualization in the Load Balance. However, the power control is
then carried out significantly faster than with the control type "SMA Home
Manager".
SMA Home Manager
LAN
(RJ45, Ethernet)
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.

With Modbus control, the excess power control can be selected according to
one or three phases.
TIP: For many of these and other manufacturers there are separate instructions
for the required settings. More information about compatible manufacturers can be
found here.
When controlled by an inverter, a feed-in meter is required in the system. The query of the
inverter otherwise provides no data.

We ask for your understanding that we cannot do any binding support for third-party
products. For questions about third-party products, please contact the technical support of the
respective company.
Not every signal source is approved for hybrid systems with battery storage. If necessary,
please contact the technical support of my-PV.
Operation with battery may require additional control parameters. In this case, please contact
the technical support of my-PV.
A number is assigned to the sensor in the order in which it is selected. The selection can be
deselected by tapping on the key once more.
To assign a sensor to the respective entry in the list, the serial numbers can be identified on a label
attached to the sensor wire.
TIP: As the measuring value of the sensor is already shown in the selection
list, an assignment can alternatively also be made by simply altering the
temperature on the sensor.
TIP: The use of a sensor is not necessary if the optional boost backup or
the legionella programme are not used and the heat generator is switched
off by a thermostat!
By saving the settings the commissioning for the use of excess power is finished.
Additional functions, such as the optional boost backup, must be set separately.

AC•THOR®/ AC•THOR®9s Operating instructions, version a0020806 8
The "Home" button always returns you to the home screen. The upper bar shows the current date,
time, the unit number und the operating mode (mode M1 –Mx). On the right, symbols show the
unit's current status.
The contents of the home screen vary according to the operating mode and shows how much power
the AC•THOR is currently feeding into the load. Depending on how many, if any, temperature
sensors are defined, the measured values are also shown.

The button "Single boost" only appears in hot water operating modes if the function for
ensuring a minimum temperature is activated. Actuating the button starts a once-only
boost backup mode. This can also be deactivated while it is in operation.
If the boost backup is actuated automatically based on the day of the week, time of day or
temperature, it cannot be deactivated by using the button.

TIP: Type directly in the diagram on the individual bars to present the data in their
next level of definition and on the button of the data logger again to return to the
previous level.
The following data can be displayed:
Total power: Shows the total power figures for all the connected loads. The yellow bars indicate the
PV excess power used, the green bars the proportion of grid energy when the optional temperature
boost backup is active.

With AC•THOR 9s, the load status (0 or 1) at the three outputs is displayed at this point.
If "none" or "0" is displayed even though a load is connected, the cause may be a thermostat that
has been switched off or a safety temperature limiter that has been triggered.
