4. Allgemeine Beschreibung

FENECON Home 6, 10 & 15 is an emergency-power-capable electrical energy storage system that can build its own household power grid. Lithium iron phosphate batteries (LiFePO4) are used in this modular system for storing electrical energy.

4.1. Explanation of the "emergency power function"

Home 10; Home 6, 10 & 15; Home 20 & 30

The FENECON series hybrid inverter:

FHI-10-DAH, FHI-10-DAH 16A, FHI-20-DAH, FHI-29,9-DAH
FINV-6-2-DAH, FINV-10-2-DAH, FINV-15-2-DAH

has an additional output for consumer loads with emergency power capability. In the event of a mains failure, the inverter disconnects the two outputs from each other at all poles, with N and PE being bridged at the emergency power output. The entire switching pattern in less than 10 ms is integrated in the inverter.

The emergency power grid is a genuine three-phase current with 100 % unbalanced load capability and a slightly increased frequency for simple synchronization when the grid returns. If the voltage is equal on all phases when the grid is restored, the switchover to parallel mains operation takes place again within a few milliseconds. The emergency power supply can only be maintained if the state of charge of the battery is sufficient. If this is not the case, the battery is charged from the connected PV strings before the emergency power grid can be black-started.

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.

6.5. Explanation of the "zero feed-in" function

FENECON GmbH hereby declares that the inverter(s):

FHI-10-DAH, FHI-10-DAH 16A, FHI-20-DAH, FHI-29,9-DAH
FINV-6-2-DAH, FINV-10-2-DAH, FINV-15-2-DAH

in combination with the FHM-120-C, FHM-C energy meters and the integrated measuring device of FINV-6-2-DAH, FINV-10-2-DAH and FINV-15-2-DAH, to which this declaration refers, supports the zero feed-in function.

For this purpose, the inverters can be configured via the FENECON Energy Management System so that 100 % of the PV energy generated is used by the inverter itself and is not fed into the public grid.
Set the "Maximum feed-in power" to 0 watts to do this.

The following deviations must be observed for the zero feed function:

FENECON WR: ± 50 W per phase

Furthermore, the accuracy depends on the power factor of the consumer loads. A high level of (distortion) reactive power has a negative effect on the accuracy of the measured active power.

The declaration applies to all identical copies of the product. The declaration loses its validity if the device is modified or connected improperly, or if it is not set up in accordance with the installation and service instructions, or if the inverter is operated with an external generator.

6.5.1. DC cable from the battery tower to the Inverter

This section can be skipped if there are several battery towers.

You will find the installation instructions for 2 or 3 battery towers in the section Electrical installation of additional battery towers.

Use the enclosed DC cable (3 m) for the t-shaped connector between the battery tower and the inverter.
Connect the cables to the battery (BAT OUT) and to the inverter (BAT).
Connect plus (+) to plus (+) and minus (-) to minus (-).
If the DC cables supplied are not long enough, the cables can be extended using the following connector types.
- 32.0270P0001 PV-KBT4-EVO ST/10X
- 32.0271P0001 PV-KST4-EVO ST/10X
Extend it by crimping and assembling a DC cable with the required dielectric strength and a cross-section of 10 mm² and the above plugs and sockets and plugging it together with the supplied cables.

The DC plugs used on the battery side are not compatible with commercially available MC4 plugs.

6.5.2. Connection and cabling of PV system

The various PV strings can be connected directly to the PV inputs on the inverter. The 6 kW variant has 2 MPPTs, each with one input (red; blue). For the 10 kW and 15 kW variants, 3 MPPTs are available, each with one input (red; blue; green)

Type 2 overvoltage protection is integrated in the inverter.

6.5.3. Communication between inverter and EMS box

Feed the enclosed communication cable (3 m network cable with open end) through one of the holes in the multi-hole seal of the communication port cover.
Leave the other openings of the multi-hole seal closed.

Variant A

A) Connect the plug of the communication cable to the inverter.

Variant B

B) Connect the plug of the communication cable to the inverter.

Attach the cover to the inverter and tighten the bolt connection.

Feed the cable through one of the four holes in the multi-hole seal.

To do this, repeat the steps from the section Assembly of battery tower 1 with FENECON EMS box. In step 8, attach the FENECON extension box instead of the FENECON EMS box.

7.2. Electrical installation of additional battery towers

7.2.1. DC cable between two battery towers and the Inverter

Use the enclosed DC cable (3 m) for the connection from the second battery tower with the attached parallel switch box to the inverter.
If the length of the DC battery cables is not sufficient, one of the enclosed sets of DC cables (2 m) can be used to extend them.
Connect the cables to the second battery tower (parallel switch box) (BAT OUT) and the inverter (BAT). (red)
Connect plus (+) to plus (+) and minus (-) to minus (-).
The two battery towers are connected to each other using the second set of cables supplied in the parallel switch box.

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:

dass vor Arbeitsbeginn an den Geräten eine angemessene Abkühlzeit einzuhalten ist,
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

Einsichern der EMS-Box (Unterverteilung, oder Steckdose).
Einsichern des Wechselrichters (Unterverteilung, Netz- und Notstromseite).
Falls vorhanden die PV-Anlage mit dem DC-Schalter am Wechselrichter zuschalten (Linke Seite des Wechselrichters).

Einsichern des Batterieturms (Front Batterieturm).
Wenn mehrere Batterietürme vorhanden sind, müssen alle Türme eingesichert werden.

Wenn die IBN bereits abgeschlossen wurde startet die Batterie und der LED Balken sollte nach ca. 60 Sekunden blinken.
The system is now ready for use.
Falls die IBN noch nicht abgeschlossen wurde, startet die Batterie nicht.
→ Konfiguration per Inbetriebnahme-Assistent.

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

Aussichern des Batterieturms (Front Batterieturm).
Wenn mehrere Batterietürme vorhanden sind, dann müssen alle Türme ausgesichert werden.

Falls vorhanden die PV-Anlage mit dem DC-Schalter am Wechselrichter ausschalten.
Rack out the inverter. (sub-distribution board, grid and emergency power side).
Aussichern der EMS-Box (Unterverteilung oder Steckdose).

Erst wenn alle LEDs am Wechselrichter und an der Batterie nicht mehr leuchten, ist das System komplett abgeschaltet. Dies kann ca. 30 Sekunden dauern.
The inverter remains on if one of the three energy sources is still active.

8.3. Configuration via commissioning wizard

9. 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 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.

In addition to the pure information display, all FEMS extensions purchased additionally , such as those 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.

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.

9.1. Access data

Der Zugang zum FEMS-Online-Monitoring ist nach Endkunden und Installateur getrennt.

9.1.1. Access for the end customer

Access for the end customer is generated automatically once commissioning is complete and sent to the end customer by email.
The terms and conditions still need to be confirmed here, then the monitoring is available without restrictions.

Sollten zusätzliche Benutzer auf die Anlage zugreifen wollen, so müssen diese einen eigenen Benutzeraccount erstellen. Dies erfolgt wie im Abschnitt Konfiguration per Inbetriebnahme-Assistent beschrieben, hier muss jedoch in der Kopfzeile "BENUTZER" ausgewählt werden.

Nach erfolgreicher Erstellung eines zusätzlichen Benutzeraccounts benötigen wir lediglich eine Mail an service@fenecon.de, mit der genutzten Mailadresse und der betroffenen FEMS-Nummer, die Verknüpfung erfolgt durch uns und somit können weitere Benutzter das Online-Monitoring einer Anlage nutzen.

9.1.2. Access for the installer

Der Installateurs-Zugang kann wie im Abschnitt Konfiguration per Inbetriebnahme-Assistent beschrieben auf der FENECON-Homepage erstellt werden. Der Zugang ist für die erfolgreiche Inbetriebnahme erforderlich.

10. Capacity expansion of the system

The capacity can also be extended at a later date, there is no time limit.

The maximum capacity is not reached with additional new battery modules, as new modules are equal to the old modules.

10.1. Capacity expansion of the battery tower
by one or more battery modules

Der Batterieturm kann auf bis zu 14 Batteriemodule in einem Batterieturm erweitert werden.

If the electrical energy storage system is expanded with additional battery modules after commissioning, proceed as follows:

After a capacity expansion, the commissioning protocol must be carried out again.

Open the Online Monitoring.
In order for the new modules to synchronize faster with the existing modules, an equal state of charge is required (30 % SoC). The electrical energy storage system automatically prepares itself if the state of charge does not have the same SoC.

Click on the "Electrical energy storage system" widget in Online Monitoring.

Activate the "Capacity expansion" function in Online Monitoring under Electrical energy storage system. The "Capacity expansion" is activated when the blue bar is displayed.
You can now choose between "Immediate start" and "Planned expansion". With the two options, the battery is charged or discharged to 30 %.
When the state of charge is reached, charging/discharging is stopped and the charge level of 30 % is maintained.

If you select "Planned expansion", you can specify the planned day and time. In this example, 24.05.2024 and the time of 09:00 were selected. At this time, the battery is expected to be charged or discharged to reach 30 % for the "Planned expansion".

You must then confirm your desired settings by clicking on the blue tick. The desired extension will be saved and, depending on the option selected, implemented immediately or later at a specific time.

Then run the commissioning wizard again.

The capacity can also be extended at a later date; there is no time limit here. You will not reach the full capacity with the new battery module, as the new module adapts to the old modules.

If the battery tower is extended by additional battery modules after several weeks or months, the following procedure must be followed:

29-30 % SoC

Das System auf einen Ladestand von 29-30 % be-/entladen; dann abschalten.

Switch off the entire system. The exact procedure is described in the section Switching the system on/off.
- Set the battery fuse switch to OFF.
- DC switch of the inverter to OFF. AC fuse on the grid and emergency power side to OFF.

Remove the top three side panels on each side.
Remove the latch up to the first battery module on both sides.

Remove the FEMS box and BMS box and place them on their sides. To do this, unscrew the wall bracket of the BMS box from the wall.

Attach new battery module.

Proceed as described in section Assembly of battery tower 1 with FEMS box, step 8.
- Attach the FENECON BMS box.
- Attach the FEMS box.
- Attach the brackets.
- Attach the side covers.

Wenn der genaue Spannungswert der alten und neuen Batteriemodule nicht getroffen wurde, kommt es zu SoC-Sprüngen, wenn die Batterie be- und entladen wird. Es steht dadurch vorübergehend nicht die volle Kapazität zur Verfügung.
Je großer die Spannungsdifferenz der "alten" und "neuen" Batterien ist, desto länger kann es dauern, bis es keine SoC-Sprünge mehr gibt und die volle Kapazität zur Verfügung steht.

11. Capacity expansion of the system
by one or more battery towers

The capacity of the system can be subsequently expanded by one or more battery towers with the same capacity. There is no time limit here.

The maximum expansion of the FENECON Home 6, 10 & 15 system comprises up to 4 battery towers, each with 3 to 14 battery modules and a maximum of 156.8 kWh.

The full capacity of new battery modules cannot be fully reached as they will adapt to the old modules.

Vor der Erweiterung muss wie folgt vorgegangen werden:

Im Online-Monitoring unter Speichersystem die Funktion "Kapazitätserweiterung" aktivieren.
Die Batterie wird auf 30 % beladen/entladen. Wenn der Ladezustand erreicht ist, wird die Beladung/Entladung gestoppt und der Ladestand gehalten.

Abschalten des kompletten Systems. Die genaue Vorgehensweise wird im Abschnitt [Ausschalten] genau beschrieben. → Sicherungsschalter der Batterie auf OFF. + → AC-Sicherung des Wechselrichters auf OFF.

Aufbau der neuen Batterietürme wie ab Abschnitt Montage — Batterieturm 1 mit FEMS-Box und Abschnitt [Erstinbetriebnahme] beschrieben.
Anschließend kann wieder alles, wie im Abschnitt [Einschalten] beschrieben, eingeschaltet werden.

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.
When the charge levels have equalized after a charging cycle, the last battery towers also switch 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.

12. 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; 10 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.

12.1. 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.

The internal relay contacts 5 and 6 can be connected via pins 5/6 and 7/8 on the Harting plug (16-pin — C).
For detailed information on connecting the heat pump, please refer to the respective manufacturer’s installation instructions.

After installing the components, the app still needs to be installed.
To do this, proceed as described in the section Activation of the app in the FEMS App Center.

12.2. 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.

So that each phase of the heating element can be controlled separately, each phase must be connected individually to a relay.
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).
Loop through the neutral conductor N via pin 9/10.
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.
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.

After installing the components, the app still needs to be installed.
To do this, proceed as described in the section Activation of the app in the FEMS App Center.

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

12.3. 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.

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

As an alternative to L2/L3, L1 can of course also be looped through, or:
Alternatively, control the contactors/relays with 24 V. If a different voltage source is used, A2 must not be connected to N.

The voltage supply of the heating element must then be connected to the switching contacts of the relays.
For detailed information on connecting the heating element, please refer to the respective manufacturer’s installation instructions.

After installing the components, the app still needs to be installed.
To do this, proceed as described in the section Activation of the app in the FEMS App Center.

12.4. 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.

The enable signal for starting the CHP can be connected to pins 5/6 via the Harting plug (16-pin — C).
For detailed information on connecting a CHP unit, please refer to the manufacturer’s installation instructions.

After installing the components, the app still needs to be installed.
To do this, proceed as described in the section Activation of the app in the FEMS App Center.

12.5. 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.

Connect the cores to pin 3/4 of the Harting plug (16-pin — A).
Connect the white core (alternative color possible) to terminal 3.
Connect the brown core (alternative color possible) to terminal 4.

For example SOCOMEC E24

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

For example KDK 4PU

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.
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.

13. Controlling the inverter externally

There are various ways to override the inverter from external devices.

13.1. 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.

Der Kleinteilebox des Wechselrichters liegen mehrere Stecker bei, die an der Unterseite des Wechselrichters angesteckt werden können.
Two 6-pin plugs are required for the ripple control receiver to function.
Die Stecker sind durchnummeriert.

Damit die Funktionen aktiviert werden, muss bei der Inbetriebnahme der Rundsteuerempfänger aktiviert werden.
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 % → Standardsignal, Wechselrichter arbeitet ohne Einschränkungen.
60 % → Wechselrichter Ausgangsleistung wird auf 60 % reduziert.
30 % → Wechselrichter Ausgangsleistung wird auf 30 % reduziert.
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.
Only the battery continues to be charged.
