Page 5: Product Introduction
Intended use Power Storage DC 8.0 and 10.0 are stationary 3-phase inverters with integrated battery charging unit. The energy from the connected solar generator and battery is converted into grid-compliant AC current and fed into the grid, while PV energy can also be charged directly DC-side into the battery. -

- Page 10 [4.2.4] Internal DC parallel connection This application only applies if several strings with the same number of modules are to be connected in parallel and the max. input current per input thus exceeds 14A. If connections are mixed up, the unit may be destroyed.
- Page 11 [4.2.6] Additional protective conductor connection figure 12 Tighten the screw connection with a torque of 2.5 Nm and carry out a figure 11 pull test to check the connection. The colour coding may differ from the illustration depending on the country. If required in the country of installation, install another protective earth conductor at the marked location on the inverter enclosure.

- Page 13 [5.3] Wiring of the RJ45 interfaces The inverter communicates with the battery via the CAN bus. If the inverter is supplied with optional Power Sensor or Power Switch, please refer to the manual of these devices for more detailed information on commissioning. Standard communication Additional communication with Power Sensor Additional communication with Power Switch.
- Page 14 For this purpose, an appropriate network cable (min. Cat5e) must be connected to the LAN port of the Power Storage DC and connected to the corresponding end device (preferably a router). The configuration of this connection is done via the menu item "Network settings" in the RCT Power APP and is explained in the manual.
- Page 15 Please note that loads that cannot be regulated can be switched off in standby current mode if the inverter is operated at an ambient temperature > 40°C. This section only applies when using the RCT Power Switch in conjunction with a battery system. Please note that correct functioning of the Power Switch is only possible,...
- Page 16 [7.2] Connecting Power Sensor The functionality of the Power Storage DC system is based on the measurement of the energy flows. This section only applies when using the RCT Power Sensor. Step description The sequence and installation direction do not have to be Place the power sensor in the house junction observed.
- Page 17 Check the cables to ensure that they are in good condition. In order to ensure the function of the DC system, an RCT Power Sensor is required that transmits the grid feed- in power to the inverter.
- Page 18 An example! The password corresponds to the serial number of your unit (see display or type plate). Start the "RCT Power" APP. Switch to "Device selection" and click on "Search". Select "10.10.100.254" (or if the unit is already renamed, select this).
- Page 19 [8.3] inverter configuration Click on “ “. Select "Login" and enter the installer password. Click on "Country and standard" and select the appropriate standard. Confirm with "Apply"." The parameters are synchronised and saved. Then click on "Finish". Then switch back to the main menu.
- Page 20 [8.4] Set system peak power and limitation For the configuration of the dynamic power reduction, no further hardware is required in addition to the power sensor. The feed-in power is measured at the grid connection point and is only limited if the power surplus exceeds the set value. In order to obtain a maximum yield from the solar system, it is possible to configure a dynamic power reduction.
- Page 21 Go to "Device" and click on "Settings" and then on "Battery". Press "Battery type" and select "Li-Ion RCT Power" or your corresponding battery type. Switch on the battery (or both batteries if present) by setting the battery ON/OFF switch to "1".

Page 22: Troubleshooting
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. -
Page 23: Maintenance
Maintenance Please follow the instructions in chapter 2.1 and switch off the unit according to chapter 10 steps 1-4. For battery maintenance, please refer to the user manual of the power battery. Before cleaning, please ensure that the DC load break switch, the on/off switch on the battery unit and the circuit breaker between the inverter and the mains are switched off. - Page 24 RCT Power GmbH. RCT Power GmbH does not accept any guarantee for damage due to faulty or lost data, due to incorrect operation or malfunction of the inverter, the software, additional devices or PCs.
