7. 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 full capacity is not achieved with new battery modules, as the new modules become similar to the old modules.

Proceed as follows before the extension:

Activate the "Capacity expansion" function in Online Monitoring under Electrical energy storage system.
The battery is charged/discharged to 30 %. When the state of charge is reached, charging/discharging is stopped and the charge level is maintained.

Switch off the entire system. The exact procedure is described in detail in the section [Switch off]. → Fuse switch of the battery to OFF. + → AC fuse of the inverter to OFF.

Assembly of the new battery towers as described from section Assembly — Battery tower 1 with FEMS box and section [Initial commissioning].
Everything can then be switched on again as described in the [Switch on] section.

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.

8. 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-Stecker 10-polig: 3 x freie Relaiskanäle (max.: 230 V; 10 A)
Harting-Stecker 16-polig: 2 x Steuerkontakte (max.: 24 V; 1 A)
- 3 x Digitale Eingänge
- 1 x Analoger Ausgang (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.

8.1. 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 plug (16-pin — C).
2. For detailed information on connecting the heat pump, please refer to the respective manufacturer’s installation instructions.

Nach der Installation der Komponenten muss die App noch installiert werden.
Hierfür wie im Abschnitt [Aktivierung der App im FEMS App Center] vorgehen.

8.2. 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 at maximum, self-generated energy is 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.

Damit jede Phase des Heizstabes separat angesteuert werden kann, muss jede Phase einzeln an einem Relais angeschlossen werden.
Hierfür die Phase 1 (braun) am Harting-Stecker (10-polig) auf Pin 3 anschließen. Von Pin 4 weiter zum Heizstab. Für die Phase 2 (schwarz) und Phase 3 (grau) werden Pin 5/6 und 7/8 verwendet.
Den Neutralleiter N über Pin 9/10 durchschleifen.
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 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.

Nach der Installation der Komponenten muss die App noch installiert werden.
Hierfür wie im Abschnitt [Aktivierung der App im FEMS App Center] vorgehen.

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

8.3. Control of a heating element greater than 6 kW (control via external relay)

Die Einbindung eines elektrischen Heizstabes ist die einfachste und günstigste Form der Sektorkopplung von Elektrizität und Wärme — oft auch "Power-to-Heat"-Anwendung genannt.

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 suit the set output of the heating element installed.

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 3 anschließen. Von Pin 4 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 5/6 und 7/8 anschließen.

Alternativ zu L2/L3 kann natürlich auch L1 durchgeschliffen werden, oder.
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.
For detailed information on connecting the heating element, please refer to the respective manufacturer’s installation instructions.

Nach der Installation der Komponenten muss die App noch installiert werden.
Hierfür wie im Abschnitt [Aktivierung der App im FEMS App Center] vorgehen.

8.4. 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 power 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.

Nach der Installation der Komponenten muss die App noch installiert werden.
Hierfür wie im Abschnitt [Aktivierung der App im FEMS App Center] vorgehen.

8.5. 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 approved by 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.

Am Harting-Stecker (16-polig — A) an Pin 3/4 die Adern anschließen.
Die weiße Ader (alternative Farbe möglich) auf Klemme 3 anklemmen.
Die braune Ader (alternative Farbe möglich) auf Klemme 4 anklemmen.

Am Beispiel SOCOMEC E24

Am Zähler wird an der Anschlussstelle 2 der braune Draht (alternative Farbe möglich) und an 3 dann die weiße Ader (alternative Farbe möglich) angeschlossen.
Am letzten Busteilnehmer muss zwischen + und - (A/B) ein Endwiderstand mit 120 Ω verbaut werden.

Am Beispiel KDK 4PU

Am Zähler wird an der Anschlussstelle 8 der braune Draht (alternative Farbe möglich) und an 7 dann die weiße Ader (alternative Farbe möglich) angeschlossen.
A 120 Ohm terminal resistor 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.

The maintenance instructions of the component manufacturer must be observed for all individual components.

The Guarantee holder is the end customer who has not purchased the system for the purpose of resale, but for his own use. Dealers, regardless of type and trading level, cannot derive any claims from this Guarantee.

11.2. Cleaning

Cleaning agents: The use of cleaning agents can damage the electrical energy storage unit and its parts.
It is recommended that the electrical energy storage unit and all its parts are only cleaned with a cloth moistened with clean water.

The entire product must be cleaned regularly. Only suitable cleaning agents may be used for this purpose.
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.

11.3. Maintenance work

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

The capacity guarantee applies if the capacity of a battery module falls below 70 % of the amount of energy shown as usable capacity before reaching 6,000 full cycles on the battery output side (DC) if a 2.2 kWh battery module has a capacity of less than 1.54 kWh. For the FENECON Home 6, 10 & 15 and FENECON Home 20 & 30 models, the amount of energy falls below 70 % of the usable capacity if a 2.8 kWh battery module has a capacity of less than 1.96 kWh.

11.4. Repairs

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

12. 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.
