3.2.1. Dimensions

The dimensions are given in mm.

Figure 1. A Inverter — Dimensions

3.3. Current-related oversizing of PV strings

PV strings may be used with the FENECON inverter, even if the MPP current \$I_(m\pp)\$ (Maximum Power Point) of the modules used exceeds the maximum input current of the inverter. In this case, the FENECON inverter limits the input current, which could lead to yield losses under certain circumstances.

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.

- 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

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 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.

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.

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 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.

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. Switching on the system

Rack in the EMS box (sub-distribution board or socket).
Rack in the inverter. (sub-distribution board, grid and emergency power side).
If available, switch on the PV system with the DC switch on the inverter. (underside of the inverter).

Racking in the battery tower (front battery tower).
If there are several battery towers, all towers must be racked in.

If the green LED on the inverter lights up during back-up, the button on the EMS box can be pressed for approx. 5 seconds.
This is only relevant if the AC supply of the battery is connected to the emergency power outlet.

When the LED bar starts flashing, the push-button can be released.

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. Switching off the system

Racking out the battery tower (front battery tower)
If there are several battery towers, all towers must be secured.

If present, switch off the PV system using the DC switch on the inverter.
Rack out the inverter. (sub-distribution board, grid and emergency power side).
Rack out the EMS box (sub-distribution board or socket).

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.
The inverter remains on if one of the three energy sources is not switched off.

9.3. Configuration via commissioning wizard

Open the homepage of FENECON 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.

https://portal.fenecon.de

All information must be filled in correctly and completely.

Once all the necessary points have been confirmed, the account will be created automatically
You will be forwarded directly to the system configuration.

First, you must enter the 16-digit installer key.
This can be found on the right-hand side of the battery tower on the type label.
Installation key: XXXX-XXXX-XXXX-XXXX
Then follow the installation wizard through the various steps.

Once commissioning is complete, the system is ready for operation and you are forwarded directly to live monitoring.

You will receive an e-mail with a summary of the complete commissioning for your records (commissioning protocol).
The customer also receives an e-mail with the personal access data for end customer monitoring.

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 withdrawal or 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 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.

10.1. Login data

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

10.1.1. Access for the end customer

Access for the end customer is generated automatically after 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.

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 e-mail to service@fenecon.de with the e-mail address used and the FEMS number concerned, we will create the link and other users can then use the Online Monitoring of an installation.

10.1.2. Access for the installer

The installer account can be created on the FENECON homepage as described in the Configuration via commissioning wizard section. Access is required for successful commissioning.

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.

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.
Für genaue Infos zum Anschließen der Wärmepumpe halten Sie sich an die Installationsanleitung des Herstellers.

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. External control of the inverter

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

12.1. Active power control with a ripple control receiver (RCR)

The active power of the home inverter can be controlled directly by the energy supply company (grid operator) via the ripple control receiver.

Figure 25. Assignment — Ripple control receiver & junction box — Communication module

Establish the connection between the ripple control receiver and the inverter. The ripple control receiver can be connected directly to the communication module of the inverter.

First connect the individual cores of the communication cable to the ripple control receiver (Illustration — RCR assignment).
Then connect the individual cores of the communication cable to the communication module of the inverter (Illustration — Assignment RCR).

Dismantle the communication module.
Feed the communication cable through the cable entry (maximum cable length 100 m).
Connect the cores of the communication cable to the appropriate pins of the communication module.

Remove jumper between pins 8 & 7.
1. The bridge between pins 9 & 10 remains in place.

Connect the reference voltage to pin 7.
1. Optional: Bridge the reference voltage on the ripple control receiver and connect a wire to pin 7 of the communication module.

Reassemble the plug.

Connect the plug to the inverter.

The behavior of the inverter in the various control stages of the ripple control receiver:

100 % → Standard signal, inverter works without restrictions (10 kW).
60 % → Inverter output power is reduced to 60 % (6 kW).
30 % → Inverter output power is reduced to 30 % (3 kW).
0 % → Inverter output power is reduced to 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.

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.

The signal can be connected to pins 4 and 5 via the Harting plug.
For detailed information on connecting the FNN control box, please refer to the manufacturer’s installation instructions.

12.3. FNN conformity

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.

14.3. 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.

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.
