Product introduction

3.1 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 the 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.

Connection 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

NOTICE
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).
4.1 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 that is exposed to sunlight (DC voltage source), high voltage is present within the inverter components which can cause fatal electric shocks.
DANGER

• 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.

WARNING
Risk of death or serious injury due to the electric arc!
When the inverter is connected to a PV array that 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:

DC].
2| Locate the ON/OFF switch of the Battery and switch to the”0” position.
3| Locate and switch off the circuit breaker, main breaker, or fuse for disconnecting the inverter from the utility grid.
4| Wait 10 minutes until capacitors have discharged and check the voltage.

4.2 Power Sensor mounting
Place the Power Sensor on a top-hat rail in the service entrance box.

4.3 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 installation of the current sensor are not important).

4.4 Connection to Power Storage DC 4.0 – 6.0
Unscrew and remove the cover of the inverter.
Open the cable gland and feed cables through the holes next to the battery inputs.
Connect the Power Sensor to the interface “C” on the BPM board of the Power Storage via a patch cable, as shown:

At last close the cover of the inverter.
4.5 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:
4.6 Connection to Power Storage AC
Unscrew and remove the cover of the inverter.
Open the cable gland and feed cables through the holes next to the battery inputs.
Connect the Power Sensor to the “B” of the Power Storage AC mainboard via a patch cable, as shown:

At last close the cover of the inverter.
4.7 Initiation and App configuration
Initiation procedure:

DC].
2| Locate the ON/OFF switch of the Battery and switch to the”1” position.
3| Locate and switch on the circuit breaker, main breaker, or fuse for connecting the inverter to the 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 permanently, Finish!|

Troubleshooting

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.

Disconnect 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
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.

“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 the absence of voltage by measuring at the DC and AC terminal block

Disposal

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 the 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.
