Within the emergency power function, the inverter acts as its own grid former and sets up its own 3-phase system for the separate emergency power branch (see Technical data). 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.

The manufacturer is not responsible for the domestic installation.

3. Likewise on all other towers, always between PARALLEL OUT and PARALLEL IN. (blue/orange)

4. At the last tower, plug the jumper plug into PARALLEL OUT. (red)

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.

NEVER unplug connections when they are live. Disconnect the energy supply first.
Batteries must not be connected or disconnected when a current is flowing.
Opening batteries is prohibited.
Before commissioning the system, ensure that the battery modules are not deeply discharged.
If the battery modules are deeply discharged, contact the FENECON Service.
Only charge deeply discharged battery modules as instructed by the FENECON Service.

This is indicated in the installation and service instructions:

that an appropriate cool-down time must be observed before starting work on the system components,
or that the risk of burns is prevented by wearing suitable protective gloves.

8.2. Switching the system on/off

8.2.1. Switch on

1. Racking in the EMS box (sub-distribution board, or socket)

2. Racking in the inverter. (sub-distribution board, grid and emergency power side)

3. If available, switch on the PV system with the DC switch on the inverter. (Left side of the inverter)

4. Racking in the battery tower (front battery tower)

5. If there are several battery towers, all towers must be secured.

6. If commissioning has already been completed, the battery will start and the LED bar should flash after approx. 60 seconds.

7. The system is now ready for use.

8. If the commissioning has not yet been completed, the battery does not start. In this case, continue with chapter 8.3.

The system is restarted by pressing the push-button on the front of the EMS box. Restarting the system can take up to three minutes.

If the system has not yet been configured, the battery goes into error mode or switches off.
This can also happen during configuration. It is therefore recommended that you only switch on the battery when you are asked to do so during the configuration process.

The inverter only starts after configuration and only then synchronizes to the grid.

8.2.2. Switch off

1. racking out the battery tower (front battery tower)

2. If there are several battery towers, all towers must be secured.

3. If present, switch off the PV system with the DC switch on the inverter.

4. Rack out the inverter. (sub-distribution board, grid and emergency power side).

5. Rack out the EMS box (sub-distribution board or socket).

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.

7. The inverter remains on if one of the three energy sources is still active.

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 following QR code or link to access the page.

1. https://portal.fenecon.de

2. Log in with your installer account.

3. If no installer account has been created yet, it can be created directly below the login window.

4. All information must be filled in correctly and completely.

5. Once all the necessary points have been confirmed, the account will be created automatically

6. You will be forwarded directly to the storage system configuration.

7. Click on the blue plus at the bottom.

8. Add FEMS.

9. First you must enter the 16-digit installer key.

10. This can be found on the right-hand side of the battery tower on the type label.

11. Installation key: XXXX-XXXX-XXXX-XXXX-XXXX

12. Then follow the installation wizard through the various steps.

13. Once commissioning is complete, the system is ready for operation and you will be taken directly to live monitoring.

You will receive a protocol of the complete commissioning for your records by e-mail.
The customer also receives an e-mail with the personal access data for end customer 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 will equalize with 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 commissioning, follow this procedure:

1. Activate the "Capacity expansion" function in online monitoring under Electrical energy storage system.

2. This charges/discharges the battery to 30 %. When the state of charge is reached, charging/discharging is stopped and the charge level is maintained.
You can choose between "Immediate start" and "Planned extension".

3. Then confirm the settings by clicking the tick button.

4. Switch off the entire system.
The exact procedure is described in detail in chapter 8.2.2.

Set the battery fuse switch to OFF.
Set the DC switch of the inverter to OFF.
AC fuse of the grid and emergency power side to OFF.

5. Remove the top three side panels on each side.

6. Remove the latch up to the first battery module on both sides.

7. Remove the EMS box and BMS box and place them on their sides. To do this, screw 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.

Attach FENECON BMS box
Attach FENECON EMS box
Add fixig plates
Attach side panels

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.
The greater the voltage difference between the "old" and "new" batteries, the longer it may take until there are no more SoC jumps and the full capacity is available.

9.2. Extension of the battery tower
by one or more battery towers

The overall capacity can be expanded later 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 commissioning, follow this procedure:

1. Activate the "Capacity expansion" function in online monitoring under Electrical energy storage system.

2. This charges/discharges the battery to 30 %. When the state of charge is reached, charging/discharging is stopped and the charge level is maintained.

3. Switching off the complete system. The exact procedure is described in detail in chapter 8.2.2.

Set the battery fuse switch to OFF.
Set the DC switch of the inverter to OFF.
AC fuse on the grid and emergency power side to OFF.

4. Set up the new battery towers as described in chapter 7.1.1 and chapter 7.1.2.

5. Carry out DC cabling as described in chapter 7.2.1 and chapter 7.2.2.

6. Wire the communication between the battery towers as described in chapter 7.3.1.

7. Everything can then be switched on again as described in chapter 8.2.1.

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.
This is not displayed as an error, but it can happen that the SoC displays of the individual battery towers show different charge levels.
If the charge levels have equalized after a charging cycle, the last battery towers will also be switched on.
The battery towers work independently, so the flashing frequency of the different towers may vary. The SoC display of the individual towers may also differ briefly.

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: 3 x free relay channels (max.: 230 V; 6 A)
Harting plug 16-pin: 2 x control contacts (max.: 24 V; 1 A)
4 x digital inputs
1 x analog output (0-10 V)

It may not be possible to connect and operate all apps at the same time.
For more information on the following apps, please visit our homepage.

100 https://fenecon.de/fenecon-fems/

If the integrated relays are not sufficient, an external 8-channel relay board can be connected via Ethernet.

The pin assignment of the Harting plug (10-pin) is shown in detail below.

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 tank 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 plug (16-pin — C).

2. For detailed information on connecting the heat pump, please refer to the respective manufacturer’s installation instructions.

Once the components have been installed, all you still require is the app.
To do so, proceed as described in Chapter 10.6.

10.2. Connecting 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 (here: electricity and heat) — often also called a "power-to-heat" application.

If the capacity of the electrical energy storage 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.

2. To do this, connect phase 1 (brown) to pin 3 on the Harting plug (10-pin). Continue from pin 4 to the heating element. Use pins 5/6 and 7/8 for phase 2 (black) and phase 3 (gray).

3. Loop through the neutral conductor N via pin 9/10.

4. A cable (5G1.5) from the sub-distribution board to the Harting plug and a cable (5G1.5) from the Harting plug to the heating element are recommended.

5. For detailed information on connecting the heating element, please refer to the respective manufacturer’s installation instructions.

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, all you still require is the app.
To do so, proceed as described in Chapter 10.6.

Manual mode is only suitable for temporary operation. For permanent operation, the external relay control must be used.

10.3. Controlling a heating element greater than 6 kW
(control via external relays)

The integration of an electric heating element is the simplest and cheapest form of sector coupling (electricity and heat) — often also called a "power-to-heat" application.

If the capacity of the electrical energy storage is exhausted, self-generated energy must be fed into the public grid at 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 power 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.

2. Connect L1 to pin 3 via a MCB B6 fused. Route phase L1 from pin 4 to the external relay and connect to A1. A2 must be connected to the neutral conductor.

3. Proceed in the same way as step 2 with the other two phases. Connect K2 and K3 via pins 5/6 and 7/8.

4. As an alternative to L2/L3, L1 can of course also be looped through, or:

5. Alternatively, control the contactors/relays with 24 V. 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.

7. For detailed information on connecting the heating element, please refer to the respective manufacturer’s installation instructions.

Once the components have been installed, all you still require is the app.
To do so, proceed as described in Chapter 10.6.

10.4. Control of a CHP unit

The integration of a combined heat and power plant (CHP) into the electrical energy management is an advanced form of sector coupling of electricity and heat.

This enables the application of the CHP unit as an electrical generator that is independent of the time of day and weather conditions. 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 of purchasing expensive electricity from the grid.

When the battery is charging, this signal is stopped again to prevent the CHP electricity from being fed into the grid unnecessarily.

1. The enable signal for starting the CHP can be connected to pins 5/6 via the Harting plug (16-pin — C).

2. For detailed information on connecting a CHP unit, please refer to the manufacturer’s installation instructions.

Once the components have been installed, all you still require is the app.
To do so, proceed as described in Chapter 10.6.

10.5. Additional AC meter

If additional 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 current transformer as an example.
Only meters approved by FENECON can be integrated.
The meter of the first generator is always integrated with Modbus ID 6. All others in ascending order. The baud rate must be 9600.

1. Connect the cores to pin 3/4 on the Harting plug (16-pin — A)

2. Connect the white core (alternative color possible) to terminal 3.

3. Connect the brown core (alternative color possible) to terminal 4.

For example SOCOMEC E24

4. The brown wire (alternative color possible) is connected to the meter at connection point 2 and the white core (alternative color possible) is then connected to 3.

5. A terminal resistor with 120 Ω must be installed between (+) and (-) (A/B) on the last bus device.

For example KDK 4PU

6. The brown wire (alternative color possible) is connected to the meter at connection point 8 and the white core (alternative color possible) is then connected to 7.

7. A terminal resistor with 120 Ohm must be installed between (+) and (-) (A/B) on the last bus device.

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, all you still require is the app.
To do so, proceed as described in Chapter 10.6.

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:

1. https://portal.fenecon.de

2. Log in with your installer account.

3. Click on the three dashes at the top left.

4. Select "Settings".

5. "FEMS App Center" click.

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.

9. Select the app to be installed

10. You will then be redirected to the installation wizard for the respective app.

11. Make settings.

12. Then click on "Install app".

11. Controlling the inverter externally

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 several plugs that can be plugged into the bottom of the inverter.

2. Two 6-pin plugs are required for the ripple control receiver to function.

3. The connectors are numbered consecutively.

4. In order for the functions to be activated, the ripple control receiver must be activated during commissioning.

5. Then confirm with OK.

The active power of the inverter can be controlled directly by the grid operator via a ripple control receiver.
The behavior of the inverter in the various control stages is described as follows:

100 % → Standard signal, inverter works without restrictions
60 % → Inverter output power is reduced to 60 %.
30 % → Inverter output power is reduced to 30 %.
0 % → Inverter output power is reduced to 0 %.

If other inverters are used, these must also be connected separately to the ripple control receiver; how exactly depends on the grid operator and the RCR used.

In the event of a curtailment to 0 %, the grid feed-in of the inverter is completely stopped, i. e. the consumption is completely supplied from the grid.

The FEMS Online Monitoring is used to visualize all energy flows in your system. The energy monitor shows live data on grid consumption or grid feed-in, PV production, charging/discharging of the battery storage system and electricity 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.

Neben der reinen Informationsdarstellung werden im Online-Monitoring auch alle zusätzlich erworbenen FEMS-Erweiterungen, wie beispielsweise zur Einbindung einer Wärmepumpe, Heizstab, E-Ladestation oder Blockheizkraftwerk (BHKW), aufgeführt. Die jeweilige Funktionsweise ist durch das entsprechende Widget steuerbar.

Zusätzlich zur Live-Ansicht bietet die Historie die Möglichkeit, selbstgewählte Zeiträume für das Online-Monitoring auszuwählen. Über das Info-Symbol kann der Status des Gesamtsystems als auch der einzelnen Komponenten zu jedem Zeitpunkt überwacht werden.

System status: Everything is OK

System state: Warning

System state: Error (Fault)

13.1.2. Troubleshooting

You can get a detailed overview of an existing warning or error by clicking on the exclamation mark in the top right-hand corner.

The scroll bar can be used to examine the origin of the warning or error in more detail.
In this example, the error lies with the controller used.

Clicking on the icon (down arrow) displays a more detailed error description depending on the error.

In the example above, an incorrect reference for the network counter was intentionally entered for test purposes, which is why the controller fails to run.

Under certain circumstances it can happen that the FEMS is not accessible and the adjacent error message appears.

If the FEMS is offline, follow the steps displayed below the message.
