3Product introduction
Intended usage
The Power Sensor 50 / 100 is used to detect the grid power feed-in or grid power consumption, at the same time the
household power is determined. The split core sensors allow easy use and installation without the separation of the current
circuit.
To obtain maximum yield out of solar plant there´s the possibility to configure a dynamic power reduction with the Power
Sensor. You can use solar power that exceeds configured power reduction threshold for self-consumption by measuring real
power feed in public grid (show Inverter Manual section 8.1.2).
Please note:
The Power Sensor 50 / 100 is not designed for any other application or connection with other devices.
Any use that differs from or goes beyond the intended usage is considered misuse.
RCT Power GmbH shall not be liable for any damage resulting from misuse.
Any misuse will cause the termination of the warranty, guarantee and general liability of the manufacturer.

4Connection of Power Sensor
Following tasks to start the Power Sensor
•4.1 Disconnecting from voltage
•4.2 Power Sensor mounting
•4.3 Split core sensors installation
•4.4 Connection to Power Storage DC
•4.5 Connection to Power Storage AC
•4.6 Initiation and App configuration
The Power Sensor may only be used with the supplied communication cable or another
Ethernet cable with the following properties (max. length: 30m, at least CAT 5 and at least
AWG 22).
Disconnecting Power Storage from voltage
Risk of death or serious injury due to electric shock!
When the inverter is connected to the utility grid (AC voltage source) and/or to a PV
array which is exposed to sunlight (DC voltage source), high voltage is present within
the inverter components which can cause fatal electric shocks.
•Any work which involves wiring, connecting or opening the inverter or the
battery housing has to be performed by qualified personnel.
•Make sure other persons keep away from cables and inner inverter parts.
Risk of death or serious injury due to electric arc!
When the inverter is connected to a PV array which is exposed to sunlight (DC
voltage source), high voltage is present within the cables and inverter components
which can cause electric arcs when DC plugs are disconnected under load.
Electric arcs can cause fatal electric shocks or burns.
Disconnection procedure:
Step
Description
1
Locate DC switch of inverter and turn to “0” position [only Power Storage DC].
2
Locate ON/OFF switch of Battery and switch to ”0” position.
3
Locate and switch off circuit breaker, main breaker or fuse for disconnecting inverter from utility grid.
4
Wait 10 minutes until capacitors have discharged and check the voltage.

7
Power Sensor mounting
Place the Power Sensor on a top-hat rail in the service entrance box.
Split core sensors installation
Click the three current sensors around the L1, L2 and L3 wires in the service entrance box (the order and direction of the
current sensors installation is not important).

Connection to Power Storage DC 4.0 –6.0
Unscrew and remove cover of inverter.
Open cable gland and feed cables trough the holes next to the battery inputs.
Connect the Power Sensor to the interface “C” on BPM board of the Power Storage via patch cable, as shown:
At last close the cover of the inverter.
Connection to Power Storage DC 8.0 –10.0
Connect the power sensor to the "Power Sensor" socket of the Power Storage DC 8.0 -10.0 using the patch cable as shown:
Connection to Power Storage AC
Unscrew and remove cover of inverter.
Open cable gland and feed cables trough the holes next to the battery inputs.
Connect the Power Sensor to the “B” of the Power Storage AC main board via patch cable, as shown:
At last close the cover of the inverter.

9
Initiation and App configuration
Initiation procedure:
Step
Description
1
Locate DC switch of inverter and turn to “1” position [only Power Storage DC].
2
Locate ON/OFF switch of Battery and switch to ”1” position .
3
Locate and switch on circuit breaker, main breaker or fuse for connecting inverter from utility grid.
During initial commissioning, the sensor is automatically arranged and flashed after the battery has been selected. All you
have to do is wait and see if the checkbox is ticked (see below)
Should it be necessary to rearrange the power sensor for some reason (rewiring or similar), please proceed as follows:
Sensor Configuration in operation mode:
Step
Description
1
Start „RCT Power App“ and connect to the device.
2
Continue with Device →Settings →Device
settings (scroll down) →Power Sensor tuning
(scroll down)
3
Remove the hook at „Current sensors are tuned“
4
The device switches off briefly and attempts to
rearrange the sensors. Once an arrangement has
been made, the hook appears again at "current
sensors are tuned" and the device restarts.
5
If current sensors are tuned and detected press
“FLASH” to store settings permanent,
Finish!

5Troubleshooting
Possible errors that occur can be read out via the existing display or also the RCT Power App. A detailed list of errors and
possible remedies can be found in the user manual. Remote access is also possible via the RCT portal. The software version of
your unit is also shown on the display or in the RCT Power App.
6Disconnect the system from the power supply
Always disconnect the system from the power supply before carrying out any work.
If you want to disconnect the unit from the power supply, please carry out at minimum steps 1-4 and 7.
Danger to life or serious injury from electric shock!
•Work involving wiring, connecting or opening the inverter enclosure must be carried out
by qualified personnel.
•Ensure that other persons stay away from cables and internal components.
Step
description
1
Turn the DC load-break switch to "0" (See Fig. 1 b).
2
Switch the battery off via the ON/OFF switch on the master, to position "0".
3
Disconnect the inverter from the grid using the external circuit breaker or main switch.
4
Wait 10 minutes until the capacitors are discharged.
5
Disconnect the DC side (PV and battery):
Remove the battery and DC connectors. Squeeze the connector latch and unplug the connector.
6
Disconnect the AC side:
Remove the cover of the inverter.
Look for the AC terminal block (see Fig. 5-1).
Press down on the terminals with an insulated screwdriver to open the terminals. Pull out the cable ends
L1, L2, L3, N and PE.
Loosen the PG gland and carefully pull out the AC cable.
Alternative:
Secure the external circuit breaker against being switched on again.
7
Determine absence of voltage by measuring at the DC and AC terminal block

7Disposal
Here you will find information on the proper disposal of electrical waste.
1 Separate collection of old appliances
Electrical and electronic equipment that has become waste is referred to as old equipment. Owners of WEEE must dispose of
it separately from unsorted municipal waste. In particular, WEEE does not belong in household waste, but in special
collection and return systems.
2 Options for the return of WEEE
Owners of old appliances from private households can return them free of charge to the collection points of the public waste
management authorities.
3. data protection
Old appliances often contain sensitive personal data. In your own interest, please note that each end user is responsible for
deleting the data on the waste equipment to be disposed of.
4 Meaning of the symbol "crossed-out dustbin
The symbol of a crossed-out dustbin regularly displayed on electrical and electronic equipment indicates
that the respective device must be collected separately from unsorted municipal waste at the end of its
service life. The appliance must not be added to household waste.
