Within the emergency power function, the Inverter acts as its own grid creator 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.

6.6.1. Configuration for zero feed-in via the FENECON Energy Management System

The inverters listed above can be configured via the FENECON Energy Management System so that the PV energy generated is used entirely by the user and is not fed-in to the public grid.
To do this, the Maximum feed-in power setting in the commissioning wizard must be set to 0 watts.

6.6.2. Notes on the zero feed-in function:

If FENECON inverters are used, deviations of < 1 % per phase may occur.
The accuracy of the zero feed-in depends on the power factor of the connected consumer loads.
A high proportion of reactive power, especially in the form of harmonics, can negatively affect the accuracy of the active power measurement.
With zero feed-in, devices that regulate to PV surplus no longer work, as there is no longer a grid feed-in to which they can regulate.

6.6.3. Validity of the declaration:

This declaration applies to all identical inverters. It loses its validity if:

changes have been made to the device,
the connection is made improperly,
the installation was not carried out in accordance with the installation and service instructions, or
the inverter is operated with an external generator.

6.6.4. 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 connection between battery tower and inverter.
Connect the cables to the battery (BAT OUT) and to the inverter (BAT1).
Connect plus (+) to plus (+) and minus (-) to minus (-).
If the DC cables supplied are not long enough, please contact your sales partner.

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

The 29.9 kW variant has two battery inputs. The FENECON Home 20 & 30 battery tower must always be connected to battery 1 (BAT1).

6.6.5. Connection and cabling of PV system

The various PV strings can be connected directly to the PV inputs on the inverter.
The 20 kW variant has 2 MPPTs, each with two inputs (red; blue).
The 29.9 kW variant has 3 MPPTs, each with two inputs (red; blue; green)

Type 2 overvoltage protection is integrated in the inverter.

6.6.6. Connecting the smart meter to the inverter

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 withdrawal or feed-in, PV production, charging/discharging of the battery energy storage system and power consumption. Other widgets show 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, combined heat and power plant (CHP), are also listed in Online Monitoring. Their functionality can be controlled via the corresponding widget.

In addition to the live view, the history offers the option of selecting self-selected time periods for Online Monitoring. The status of the entire system and the individual components can be monitored at any time using the info symbol.

9.1. Access data

Access to FEMS Online Monitoring is separated according to end customer and installer.

9.1.1. Access for the end customer

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

If additional users want to access the system, they must create their own user account. This is done as described in the section Configuration via commissioning wizard, but here "USER" must be selected in the header.

After successfully creating an additional user account, all we need is an email to service@fenecon.de with the email address used and the FEMS number concerned, we will create the link and other users can use the Online Monitoring of a system.

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

Der Batterieturm kann auf bis zu 15 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 wizard must be carried out again.

Das System führt automatisch einen Referenzzyklus durch, berechnet bei geplanter Erweiterung den passenden Startzeitpunkt und bereitet die Batterie auf einen stabilen Zielwert von 30 % SoC vor.

Ablauf:

ab 70 % SoC: Laden auf 100 %, Haltezeit, danach Entladen auf 30 %
unter 70 % SoC: Entladen auf 0 %, Haltezeit, danach Laden auf 30 %

Empfehlung: Vorab möglichst einige vollständige Zyklen von 0-100 % durchführen, besonders bei älteren Batterien.

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 extension". 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 extension", 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 extension".

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 will equalize with 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

Charge/discharge the system to a charge level of 29-30 %; then switch off.

Switch off the entire system. The exact procedure is described in the section Switching 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 side. To do this, screw the wall bracket of the BMS box from the wall.

Attach new battery module.

Proceed as described in section [Assembly — Battery tower 1 with FEMS box], step 8.
- Attach the FENECON BMS box.
- Attach the FEMS box.
- Attach the locks.
- Attach the side covers.

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. This means that the full capacity is temporarily not available.
The greater the voltage difference between the "old" and "new" batteries, the longer it can take until there are no more SoC jumps and the full capacity is available.

10.2. 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.

Der Maximalausbau des FENECON Home 20 & 30-Systems umfasst bis zu 4 Batterietürme mit je 4 bis 15 Batteriemodulen und maximal 168 kWh.

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

Das System führt automatisch einen Referenzzyklus durch, berechnet bei geplanter Erweiterung den passenden Startzeitpunkt und bereitet die Batterie auf einen stabilen Zielwert von 30 % SoC vor.

Ablauf:

ab 70 % SoC: Laden auf 100 %, Haltezeit, danach Entladen auf 30 %
unter 70 % SoC: Entladen auf 0 %, Haltezeit, danach Laden auf 30 %

Empfehlung: Vorab möglichst einige vollständige Zyklen von 0-100 % durchführen, besonders bei älteren Batterien.

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 Switching 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 Switching on the system 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.

11. FEMS extensions

For the following FEMS extensions, the integrated relays can be used directly on the (first) battery tower.
Various pins on the Harting plugs 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)
- 3 x digital input
- 1 x digital input for § 14a
- 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://www.fenecon.de/fems-apps/

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.

11.1. 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 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.

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 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.

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 called a "power-to-heat" application.

If 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 current for water heating (e. g. for hot water buffer tanks, pool heating, etc.). 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 manufacturer’s installation instructions.

	NOTICE
Mögliche Beschädigung des Systems Schäden am System durch die Verwendung von nur einer Phase für den Anschluss. Verwenden Sie drei verschiedene Phasen für den Anschluss.

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.

Der manuelle Modus ist nur für den vorübergehenden Betrieb geeignet. Für den dauerhaften Betrieb ist die externe Relaisansteuerung zu verwenden.

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

The externally installed relays must be laid out according to the 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 neutral.
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 another voltage source is used, do not connect A2 to N.

The power 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 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.

11.4. Controlling 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 allows using the CHP as an electrical generator that is independent of the time of day and weather conditions. When the state of charge of the electrical energy storage system is low, the CHP is given a switch-on signal to produce electricity. 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 current from the grid.

When the battery is charging, this signal is stopped again to prevent the CHP’s current 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 the CHP, 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.

11.5. Additional AC meter

If additional meters have been installed for monitoring other consumer loads 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 production meter is always integrated with Modbus ID 6. All others in ascending order. The baud rate is 9600.

Connect the cores to pin 3/4 on 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 Ω 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.
Link to the overview page of the installation and configuration instructions for energy meters

Once the components have been installed, 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.

11.6. Activation of the app in the FEMS App Center

Illustration 48. App installation — Variant 2 — Step 5

14. External control of the inverter

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

Illustration 49. Connection — Curtailment via ripple control receiver

14.1. Ripple control receiver at the AC output

The inverter can be controlled directly via a ripple control receiver. The following plugs supplied with the inverter are required for this.

The inverter’s small parts box contains three plugs that can be plugged into the underside of the inverter.

The plugs are numbered consecutively.

In order for the functions to be activated, activate the ripple control receiver during commissioning.
Then confirm with OK.

The active power of the FENECON Home 20 & 30 inverter can be controlled directly by the energy supply company (grid operator) via a ripple control receiver (RCR).
The behavior of the inverter in the various control stages can be described as follows.

100 % → Standard signal, inverter works 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 RCR; 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 stopped completely, i.e. the consumer loads are supplied completely from the grid.
Only the battery continues to be charged.

A cable with at least 5 cores with a cross-section of 0.34 mm² to 0.75 mm² is recommended.
Feed the cable through one of the holes of the multi-hole seal.
Attention: One feedthrough is already blocked by the communication cable between the inverter and EMS.
Leave the other openings of the multi-hole seal closed.

Connect the cores of the control cable as shown in the picture.

In order for the inverter to synchronize to the grid, a jumper must be connected between pin 7 and pin 8.
A core with a cross-section of 0.34 mm² to 0.75 mm² is recommended.

Plug in the two connectors on the underside of the inverter.

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

14.2. Ripple control receiver on grid connection point

The system can be controlled directly via the ripple control receiver (RCR).

ACHTUNG: Beachten Sie hierbei die Vorgaben Ihres Netzbetreibers bei Anschluss des externen Funkrundsteuerempfängers.

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

The behavior of the inverter in the various control stages can be described as follows:

100 % → Standard signal, inverter works without restrictions (20/30 kW).
60 % → Feed-in power at the grid connection point is reduced to 60 % (12/18 kW).
30 % → Feed-in power at the grid connection point is reduced to 30 % (6/9 kW).
0 % → Feed-in power at the grid connection point is reduced to 0 % (0/0 kW).

When connecting to the FEMS box, the following contacts must be connected in the Harting plug:

Illustration 50. Connection — Ripple control receiver on GCP — Home 20 & 30

During commissioning, the dynamic ripple control receiver must be selected under External limitations:

The ripple control receiver now regulates the grid limitation to the grid connection point and no longer to the AC output. This means that it is also possible to charge the battery and supply the consumer loads with PV production in the event of grid limitation.

Illustration 51. Connection — Curtailment via ripple control receiver

14.3. Remote shutdown

The inverter can be disconnected from the grid when remote disconnection is activated, e. g. via a central grid and plant protection. One of the following plugs supplied with the inverter is required for this.

The inverter’s small parts box contains three plugs that can be plugged into the underside of the inverter.

The plugs are numbered consecutively

To activate the functions, the remote switch-off must be activated during commissioning.
Then confirm with OK.
Continue to the next step with Next.

The emergency power output is still active (if activated) and supplies the emergency power to the consumer loads.

A cable with 2 cores and a cross-section of 0.34 mm² to 0.75 mm² is recommended.
Feed the cable through one of the holes in the multi-hole seal of the cover.
Attention: One feedthrough is already blocked by the communication cable between the inverter and EMS.
Leave the other openings of the multi-hole seal closed.

The core of the disconnection device must be connected to pin 7 and pin 8 so that the inverter can be disconnected from the grid.
The switch-off device must be equipped with a break contact
→ In normal operation, pins 7 and 8 must be bridged via the switch-off device.

Plugging in the 7-pin connector on the underside of the inverter.

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

This method can also be used to connect P,ave monitoring.

14.4. Section 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.

The signal can be connected to pins 1 ( C ) and 8 ( A ) via the Harting plug (16-pin — A & C).
For detailed information on connecting the FNN control box, please refer to the manufacturer’s installation instructions.

16.3. Maintenance work

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

Regular re-referencing of the electrical energy storage system is recommended, i.e. it must be completely discharged (SoC = 0 %) and then fully charged again (SoC = 100 %), as otherwise capacity may be lost.

16.4. Repairs

In the event of defective components, contact FENECON Service.

16.5. Warranty cases

Warranty claims must be reported to FENECON in text form (e. g. by e-mail) within the warranty period. The notification must be made within a cut-off period of 8 weeks after the end customer has become aware of the warranty claim or could have become aware of it without gross negligence.

17. Advice for fire departments when dealing with FENECON Home & Commercial 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.

Illustration 53. Installation — Maintenance switch using the example of Home 20/30

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

18. Flood safety measures FENECON Home & Commercial

First steps after the water has receded

Even if your battery energy storage system looks undamaged on the outside:

Do not put the system back into operation yourself.
Ventilate the room well before entering (open windows from the outside if possible).
Avoid sparks (no smoking, no lighters).

Why a review is important:

Even though LFP batteries are very safe, water or moisture can:

Cause short circuits in the electronics.
Trigger corrosion of electrical connections.
Create isolation problems that only become apparent later.

These problems do not have to occur immediately, but can develop over weeks.

Commission a professional inspection

Please contact:

Your installer or a qualified electrician with experience in battery energy storage systems.
FENECON, the manufacturer of your system.
Your insurance company — document the damage with photos.

The qualified specialist will check:

Whether water has entered the system.
Whether electronic components have been damaged.
Whether a recommissioning is safely possible or a replacement is necessary.

No recommissioning without approval

Battery energy storage systems that have come into contact with water must only be put back into operation after a professional inspection and express approval by a qualified specialist. This is for your safety and is often also a prerequisite for your insurance cover.

When replacement is necessary

If your electrical energy storage system needs to be replaced:

The disposal of the defective system must be carried out professionally by specialized companies.
Your installer will usually organize the removal and disposal.
Do not attempt to transport damaged batteries yourself

Storage disposal until collection

If damaged battery modules cannot be collected immediately:

Store them well ventilated outdoors with sufficient clearance from flammable materials.
Storage in a
- Sand bed.
- Fireproof container, not gas-tight, ventilated.
- Water bath, e. g. metal tub, completely covered with water.
