3.3. Current-related oversizing of PV strings

PV-Strings dürfen mit dem FENECON-Wechselrichter eingesetzt werden, auch wenn der MPP-Strom \$I_(m\pp)\$ (Maximum Power Point) der eingesetzten Module den maximalen Eingangsstrom des Wechselrichters überschreitet. Dabei limitiert der FENECON-Wechselrichter den Eingangsstrom, was unter Umständen zu Ertragsverlusten führen könnte.

The expected short-circuit current of the PV string \$I_(sc)\$ must not exceed the maximum short-circuit strength of the inverter in any operating state. Such an exceedance could damage the inverter and would lead to the exclusion of warranty claims in accordance with the warranty conditions of FENECON.

Ensure that the load of the inverter on the emergency power side does not exceed 3.33 kW per phase. *This also applies to parallel mains operation.

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

FENECON GmbH hereby declares that the inverter(s):

FENECON WR: FHI-10-DAH, FHI-10-DAH 16A, FHI-20-DAH, FHI-29,9-DAH

in combination with the FHM-120-C, FHM-C energy meters, 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.

Sie finden die Aufbauanleitung für 2 oder 3 Batterietürme im Abschnitt Montage weiterer Batterietürme.

Das beiliegende 1,5 m-DC-Kabel für die Verbindung von Batterieturm und Wechselrichter verwenden.
If the length of the DC battery cables is not sufficient, a standard PV cable with at least 6 mm² can be used. For the connectors, a set of MC4 connectors is required on the battery side and a set of Phoenix Contact Sunclix connectors on the inverter side.
Connect the cables to the battery (BAT OUT) and to the inverter (BAT).
Connect plus (+) to plus (+) and minus (-) to minus (-).

And connect the other two cables to the third battery (BAT OUT) and the second battery (BAT IN) (green).

7.3. Communication of further battery towers

7.3.1. Communication between two battery towers

Wenn zwei Batterietürme betrieben werden, dann muss zwischen den beiden Türmen das beiliegende Netzwerkkabel zwischen
- Turm 1 PARALLEL OUT und Turm 2 PARALLEL IN gesteckt und verriegelt werden.
On the second tower, the jumper plug must be set to PARALLEL OUT.

7.3.2. Communication between three battery towers

Wenn drei Batterietürme betrieben werden, dann müssen zwischen den drei Türmen die beiliegenden Netzwerkkabel zwischen
- Turm 1 PARALLEL OUT und Turm 2 PARALLEL IN und zwischen
- Tower 2 PARALLEL OUT and Tower 3 PARALLEL IN are plugged in and locked.
Bei drei Türmen wird die Endbrücke nicht benötigt.

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

The battery tower can be expanded to up to 10 battery modules in one battery tower.

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.

8. 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 10 Gen. 1 system comprises up to 3 battery towers, each with 4 to 10 battery modules and a maximum of 66 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.

9. Initial commissioning

9.1. 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.

9.2. Switching the system on/off

9.2.1. 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. (Unterseite Wechselrichter).

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

Wenn am Wechselrichter die grüne LED bei Back-Up leuchtet, kann die Taste an der EMS-Box für ca. 5 Sekunden gedrückt werden.
Dies ist nur relevant, wenn die AC-Versorgung der Batterie am Notstromabgang angeschlossen ist.

Wenn der LED-Balken zu blinken beginnt kann der Taster losgelassen werden.

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 prompted to do so during the configuration process.

9.2.2. 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.

9.3. Configuration via commissioning wizard

10. 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.

10.1. Access data

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

10.1.1. 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.

10.1.2. 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.

11. FEMS extensions

The integrated relays can be used directly on the (first) battery tower for the following FEMS extensions. Various pins on the 16-pin connector plug are provided for this purpose. A total of three free relay channels are available.
Not all apps can be connected at the same time.
For further information on the following apps, please visit our homepage.

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

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

The pin assignment of the Harting plug can be seen in detail below.

Table 37. Connector pin assignment
Item	Description
1	RS485 connection
2	Additional PE
3	Digital inputs DI1-DI4 (currently not available)
4	+12 V DC
5	Relay 1

7	Relay 3

11.1. Connection of a heat pump via "SG-Ready"

The integration of an "SG-ready heat pump" (smart grid-ready) 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 electrical energy storage system at times when cheap (solar) electricity is available in order to save electrical energy at times when there is no cheap surplus electricity.

Die internen Relaiskontakte 2 und 3 können über die Pins 13/14 und 15/16 am Harting-Stecker angeschlossen werden.
For detailed information on connecting the Heat pump, please refer to the manufacturer’s installation instructions.

11.2. 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.
When the capacity of the electrical energy storage system is exhausted, self-generated energy must be fed into the public grid at a 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.

Damit jede Phase des Heizstabes separat angesteuert werden kann, muss jede Phase einzeln an einem Relais angeschlossen werden.
Hierfür die Phase 1 (braun) auf Pin 11 anschließen. Von Pin 12 weiter zum Heizstab. Für die Phase 2 (schwarz) und Phase 3 (grau) werden Pin 13/14 und 15/16 verwendet.
Die Relais mit dem Heizstab müssen mit einem LS B10 vorgesichert werden.
Es wird ein Kabel (5G1,5) von der Unterverteilung zum Harting-Stecker und ein Kabel (5G1,5) vom Harting-Stecker zum Heizstab empfohlen.
For detailed information on connecting the Heat pump, please refer to the manufacturer’s installation instructions.

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

11.3. 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 referred to as a "power-to-heat application".
When the capacity of the electrical energy storage system 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 storage 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.

Damit jede Phase des Heizstabes separat angesteuert werden kann, muss jede Phase einzeln über ein zusätzliches externes Relais an dem internen Relais angeschlossen werden.
L1 über einen LS B6 abgesichert an Pin 11 anschließen. Von Pin 12 die Phase L1 weiter zum externen Relais führen und an A1 anklemmen. A2 muss mit dem Neutralleiter verbunden werden.
Mit den beiden anderen Phasen gleich zu Schritt 2 verfahren. K2 und K3 über die Pins 13/14 und 15/17 anschließen.

Alternativ zu L2/L3 kann natürlich auch L1 durchgeschliffen werden … oder

… alternativ die Schütze/Relais mit 24 V ansteuern. Wenn eine andere Spannungsquelle verwendet wird, dann darf A2 nicht mit N verbunden werden.

Die Spannungsversorgung des Heizstabs muss dann mit den Schaltkontakten der Relais verbunden werden. Wenn eine andere Spannungsquelle verwendet wird, dann darf A2 nicht mit N verbunden werden.
For detailed information on connecting the heat pump, please refer to the respective manufacturer’s installation instructions.

11.4. 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 charging, this signal is stopped again to prevent the CHP unit from feeding electricity into the grid unnecessarily.

Das Freigabesignal für den Start des BHKW kann über die Pins 11/12 angeschlossen werden.
For detailed information on connecting the CHP unit, please refer to the manufacturer’s installation instructions.

11.5. 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 Socomec Countis E24 as an example.
Only meters 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.

Statt die Kommunikationsleitung des Wechselrichters direkt auf Pin 1/2 aufzulegen, wie in Kapitel 6.3.8 beschrieben, muss auf Pin 1/2 die Kommunikationsleitung zum Zähler angeschlossen werden.
1. Weiß auf 1; braun auf 2.

Vom Zähler wird dann die Verbindung zum Wechselrichter hergestellt. Somit müssen am Zähler jeweils zwei Adern an einen Anschluss aufgelegt werden.

12. Controlling the inverter externally

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

12.1. Wirkleistungssteuerung mit einem Rundsteuerempfänger (RSE)

Die Wirkleistung des Home-Wechselrichters kann direkt vom Energieversorgungsunternehmen (EVU) über den Rundsteuerempfänger gesteuert werden.

Figure 25. Belegung — Rundsteuerempfänger & Anschlussbereich — Kommunikationsmodul

Stellen Sie die Verbindung zwischen Rundsteuergerät und Wechselrichter her. Der Rundsteuerempfänger kann direkt am Kommunikationsmodul des Wechselrichters angeschlossen werden.

Die einzelnen Adern des Kommunikationskabels zuerst am Rundsteuerempfänger anklemmen (Abbildung — Belegung RSE).
Dann die einzelnen Adern des Kommunikationskabels am Kommunikationsmodul des Wechselrichters anklemmen (Abbildung — Belegung RSE).

Kommunikationsmodul auseinanderbauen.
Kommunikationskabel durch die Kabeleinführung führen (maximale Kabellänge 100 m).
Adern des Kommunikationskabels an den passenden Pins des Kommunikationsmoduls anklemmen.

Brücke zwischen Pins 8 & 7 entfernen.
1. Die Brücke zwischen Pins 9 & 10 bleibt bestehen.

Die Referenzspannung an Pin 7 anklemmen.
1. Optional: Die Referenzspannung am Rundsteuerempfänger brücken und einen Draht an Pin 7 des Kommunikationsmoduls anklemmen.

Stecker wieder zusammenbauen.

Stecker am Wechselrichter anstecken.

Das Verhalten des Wechselrichters in den verschiedenen Regelstufen des Rundsteuerempfängers:

100 % → Standardsignal, Wechselrichter arbeitet ohne Einschränkungen (10 kW).
60 % → Wechselrichter Ausgangsleistung wird auf 60 % reduziert (6 kW).
30 % → Wechselrichter Ausgangsleistung wird auf 30 % reduziert (3 kW).
0 % → Wechselrichter Ausgangsleistung wird auf 0 % reduziert (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.

12.2. § 14a of the Energy Industry Act (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.

Das Signal kann über den Harting-Stecker an den Pins 4 und 5 angeschlossen werden.
For detailed information on connecting the FNN control box, please refer to the manufacturer’s installation instructions.

12.3. FNN conformity

Proof of conformity according to FNN document:
"Connection and operation of electrical energy storage systems on the low-voltage grid"

Requirement FNN document
*"Connection and operation of electrical energy storage systems on the low-voltage grid", 4.10:

The cleaning agents must be free of chlorine, bromine, iodine or their salts. Steel wool, spatulas and the like must never be used for cleaning. The use of unsuitable cleaning agents can lead to external corrosion.

14.3. Wartungsarbeiten

No regular maintenance work needs to be carried out on the system, but check the status of your Storage unit regularly.

Eine regelmäßige Neu-Referenzierung des Speichers wird empfohlen, d. h., dass dieser vollständig entladen (SoC = 0 %) und anschließend wieder vollständig beladen werden muss (SoC = 100 %), da es sonst ggf. zu Kapazitätsverlusten kommen kann.

14.4. Repairs

The FENECON service must be contacted in the event of defective components.

15. Information for fire departments when handling FENECON home and commercial battery energy storage systems

The FENECON home and commercial systems operate in the low-voltage range, which means that they are operated with voltages of less than 1,500 volts direct current (DC) and less than 1,000 volts alternating current (AC).

It may be useful to install an additional switch that disconnects the building from the emergency power supply. This makes it easier for the fire department to act safely and quickly in an emergency.

For a precise procedure for emergency services, it is recommended to ask the relevant fire department schools and request the corresponding information sheets and pocket cards for battery storage systems.
