Compared to the public grid system, the Grid shape of the emergency power mode has a lower "buffer effect" with regard to load peaks, starting currents, DC components and strongly fluctuating Loads. Due to the limited power of the Inverter, such loads are only possible within certain limits. |

7.3. Communication of further battery towers
7.3.1. Communication between two to four battery towers
1. If several battery towers are operated in parallel, the network cable supplied with the Parallel Box and Extension Box must be used between the towers. (green) |
8. Initial commissioning
8.1. Checking the installation, connections and cabling
Check the system as follows before initial commissioning:
-
All components (distances, environment, mounting) are installed correctly.
-
All internal wiring is complete and properly connected.
-
All external supply lines (power supply, communication cable) are properly connected.
-
All connected loads are matched to the system and the necessary settings have been made.
-
All necessary tests of the system were carried out in accordance with the standards.
Commissioning may only be carried out by trained specialist personnel. |
|
This is indicated in the operating instructions:
|
8.2. Switching the system on/off
8.2.1. Switch on
1. fuse the EMS box (sub-distribution board, or socket outlet) |
|
4. Secure the battery tower (front battery tower) |
|
6. If the IBN has already been completed, the battery starts and the LED bar should flash after approx. 60 seconds. |
The system is restarted by pressing the button on the front of the EMS Box. This can take up to three minutes until the system is up and running again. |
If the system has not yet been configured, the battery goes into error mode or switches off. The Inverter only starts after configuration and only then synchronizes to the Grid. |
8.2.2. Switch off
1. securing the battery tower (front battery tower) |
|
3. If present, switch off the PV system using the DC switch on the Inverter. |
|
6. The system is only completely switched off when all LEDs on the Inverter and the battery are no longer lit. This can take approx. 30 seconds. |
8.3. Configuration via commissioning wizard
Open the FENECON homepage and click on the login for FEMS online monitoring "FEMS Login" in the top right-hand corner. Alternatively, you can use the QR code below or the link to access the page.
2. Log in with your installer account. |
|
3. If an installer account has not yet been created, it can be created directly under the login window. |
|
5. Once all the necessary points have been confirmed, the account will be created automatically |
|
7. Click on the blue plus at the bottom. |
|
9. First you must enter the 16-digit installer key. |
|
13. Once the IBN is complete, the system is ready for operation and you will be forwarded directly to live monitoring. |
|
9. Capacity expansion of the system
The capacity can also be extended at a later date, there is no time limit.
It will not reach full capacity with the new battery module, as the new module adapts to the old modules.
9.1. Capacity expansion of the battery tower
by one or more battery modules
The battery tower can be stacked up to 15 battery modules to form a battery tower.
If further battery modules are added after the IBN, the following procedure must be followed:
1. Activate the "Capacity expansion" function in online monitoring under Storage system. |
|
4. Shut down the entire system. The exact procedure is described in detail in chapter 8.2.2. |
|
5. remove the top three side panels on each side. |
|
7. Remove the EMS box and BMS box and place them on their sides. To do this, unscrew the wall bracket of the BMS box from the wall. |
|
8. Attach the new battery module. |
|
9. Proceed as described in chapter 6.2.4 from step 8. |
|
10. Run the commissioning wizard again. |
If the exact voltage value of the old and new battery modules has not been matched, SOC jumps will occur when the battery is charged and discharged. As a result, the full capacity is temporarily not available. |
9.2. Extension of the battery tower
by one or more battery towers
The capacity can be subsequently expanded by one or more battery towers with the same capacity. Up to four battery towers can be operated in parallel.
If further battery modules are added after the IBN, the following procedure must be followed:
1. Activate the "Capacity expansion" function in online monitoring under Storage system. |
|
3. Switching off the entire system. The exact procedure is described in detail in chapter 8.2.2. |
|
4. installation of the new battery towers as described in chapter 7.1.1 and chapter 7.1.2. |
|
8. Run the commissioning wizard again. |
If the exact voltage value of the old and new battery towers has not been matched, the new batteries will not be connected. |
10. FEMS extensions
The integrated relays can be used directly on the (first) battery tower for the following FEMS extensions.
Various pins on the Harting connectors are provided for this purpose.
-
Harting plug 10-pin: 3x free relay channels (max.: 230 V; 6 A)
-
Harting plug 16-pin: 2x control contacts (max.: 24 V; 1 A)
-
3x digital inputs
-

10.1. Connection of a Heat pump via "SG-Ready"
The integration of an "SG-Ready" (Smart Grid-Ready) Heat pump is an advanced form of sector coupling of electricity and heat - often also referred to as a "Power-to-Heat" application. The control system ensures that the Heat pump slightly overheats the thermal storage unit at times when cheap (solar) electricity is available in order to save electrical energy at times when there is no cheap surplus electricity.
1. The internal relay contacts 5 and 6 can be connected via pins 5/6 and 7/8 on the Harting connector (16-pin — C). |
Once the components have been installed, the app still needs to be installed. |
10.2. Connection of a Heating element with a maximum of 6 kW
The integration of an electric Heating element is the simplest and cheapest form of sector coupling of electricity and heat - often also referred to as a "power-to-heat" application.
If the capacity of the electrical storage unit is exhausted, self-generated energy must be fed into the public Grid with low remuneration. In these cases, it often makes sense to use the surplus electricity for water heating (e.g. for hot water buffer tanks, pool heating, etc.). In this way, other energy sources (e.g. wood or oil) can be saved.
1. So that each phase of the Heating element can be controlled separately, each phase must be connected individually to a relay. |
Care must be taken to ensure that three different phases are used. If only one phase is used, damage may occur. |
Once the components have been installed, the app still needs to be installed. |
Manual mode is only suitable for temporary operation. For permanent operation, the external relay control must be used. |
10.3. Control of a Heating element greater than 6 kW
(control via external relay)
The integration of an electric Heating element is the simplest and cheapest form of sector coupling of electricity and heat — often also called a "power-to-heat" application.
If the capacity of the electrical storage unit is exhausted, self-generated energy must be fed into the public Grid with low remuneration. In these cases, it often makes sense to use the surplus electricity for water heating (e.g. for hot water buffer tanks, pool heating, etc.). In this way, other energy sources (e.g. wood or oil) can be saved. The externally installed relays must be designed according to the installed output of the installed Heating element.
1. So that each phase of the Heating element can be controlled separately, each phase must be connected individually to the internal relay via an additional external relay. |

4. As an alternative to L2/L3, L1 can of course also be looped through, or +. 5. Or alternatively control the contactors/relays with 24V. If a different voltage source is used, A2 must not be connected to N. |
|
6. The voltage supply of the Heating element must then be connected to the switching contacts of the relays. |
Once the components have been installed, the app still needs to be installed. |
10.4. Control of a CHP unit
The integration of a Combined heat and power plant (CHP) into electrical energy management is an advanced form of sector coupling of electricity and heat.
This makes it possible to utilize the property of the CHP unit as an electrical generator that is independent of the time of day and weather conditions. For example, the CHP unit is given a switch-on signal to produce electricity when the storage unit’s charge level is low. This is useful, for example, if the battery capacity is not sufficient to cover electricity consumption at night. This avoids the need to purchase expensive electricity from the Grid.
When the battery is charged, this signal is stopped again to prevent the CHP power from being fed into the grid unnecessarily.
1. The enable signal for starting the CHP unit can be connected to pins 5/6 via the Harting connector (16-pin — C). |
Once the components have been installed, the app still needs to be installed. |
10.5. Additional AC meter
If other meters have been installed for monitoring other consumers or generators, these must be integrated into the circuit in accordance with the manufacturer’s instructions.
The communicative integration is shown below using a 3-phase sensor without a current transformer as an example.
Only meters that have been approved by the company FENECON can be integrated.
The first generation meter is always integrated with Modbus ID 6. All others in ascending order. The baud rate must be 9600.
1. Connect the wires to pin 3/4 on the Harting connector (16-pin — A) |
|
"Using SOCOMEC E24 as an example" |
|
"Using KDK 4PU as an example" |
If several meters are to be installed, they can be connected in series for communication purposes. For this purpose, the first meter can be bridged to the second, etc. The Modbus address must be set in ascending order. |
Once the components have been installed, the app still needs to be installed. |
10.6. Activation of the app in the FEMS App Center
After installing the hardware FEMS extension, it still needs to be activated in the App Center. To do this, proceed as follows.
2. Log in with your installer account. |
|
3. Click on the three dashes at the top left. |
|
4. select "Settings" |
|
5. click "FEMS App Center" |
|
6. Click on "Redeem license key" to open a new window. |
|
7. Enter the license key and click "Validate license key". (The license key must be purchased in advance). |
|
If the validation was successful, a list of the respective apps that can be installed with the redeemed license key is displayed in a selection. |
|
10. You will then be redirected to the installation wizard of the respective app. |
11. External control of the Inverter
There are various ways to override the Inverter from external devices.
11.1. Ripple control receiver
The Inverter can be controlled directly via a ripple control receiver. The following plugs supplied with the Inverter are required for this.
1. The small parts box of the Inverter comes with three plugs that can be plugged into the bottom of the Inverter. |
|
2. The plugs are numbered consecutively. |
|
3. To activate the functions, the ripple control receiver must be activated during commissioning. |
The active power of the FENECON Home 20 & 30 inverter can be controlled directly by the energy supply company (EVU) via a ripple control receiver (RSE).
The behavior of the Inverter in the various control stages can be described as follows.
-
100 % → standard signal, Inverter operates without restrictions (20/30 kW)
-
60 % → Inverter output power is reduced to 60 %. (12/18 kW)
-
30 % → Inverter output power is reduced to 30 %. (6/9 kW)
-
0 % → Inverter output power is reduced to 0 %. (0/0 kW)
If other inverters are used, these must also be connected separately to the RSE; how exactly depends on the grid operator and the RSE used.
Grid feed-in from the Inverter is stopped completely when the load is reduced to 0 %, i.e. the Consumption is supplied completely from the Grid. |
1. A cable with at least 5 cores with a core cross-section of 0.34 mm2 to 0.75 mm2 is recommended. |
5. Connect the wires of the control cable as shown in the picture. |
6. A jumper must be connected between pin 7 and pin 8 so that the Inverter synchronizes to the Grid. |
8. Connect the two plugs to the bottom of the Inverter. |
9. Attach the cover to the inverter and tighten the screw connection. |
11.2. § Section 14a EnWG
The Inverter can be limited to a maximum reference power of 4.2 kW. The digital input of the EMS must be assigned for this.
1. The signal can be connected to pins 1 (C) and 8 (A) via the Harting connector (16-pin — A & C). |
12. FEMS-Online-Monitoring
The FEMS online monitoring is used to visualize all energy flows in your system. The energy monitor shows live data on grid consumption or feed-in, PV production, charging/discharging of the battery storage system and power consumption. Other widgets display the percentage of self-sufficiency and self-consumption. In addition, the individual widgets offer a detailed view, which can also be used to view the performance values with phase accuracy.
In addition to the pure information display, all additionally purchased FEMS extensions, such as for integrating a Heat pump, Heating element, e-charging station or Combined heat and power plant (CHP), are also listed in the online monitoring. Their functionality can be controlled via the corresponding widget.
In addition to the live view, the history offers the option of selecting user-defined time periods for online monitoring. The status of the entire system and the individual components can be monitored at any time using the info icon.
