When the charge level is reached, charging/discharging is stopped and the charge level of 30% is maintained.

When you select the "Planned extension", you can select the planned day and the planned 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/discharged to reach 30% for the "Planned extension".

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

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

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

2. Switch off the entire system. The exact procedure is described in detail in chapter 9.2.2.
- 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.

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

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

6. Attach the new battery module.

7. Proceed as described in chapter 6.2.4 from step 8.
- FENECON Home 10 - Attach BMS box
- FENECON Home 10 - Attach EMS box
- Attach locks
- Attach 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 [.SpellE]#is charged and discharged. This means that the full capacity is temporarily not available.
After approx. 20 cycles, the cells should have equalized and there are no more jumps and the capacity is also fully usable.

7.5. Extension of the battery tower by one or more battery towers

Up to three battery towers can be operated in parallel.

The capacity can also be subsequently increased by adding one or two more battery towers of the same capacity; there is no time limit for this. 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 further battery towers after several weeks or months, the following procedure must be followed:

29-30 % SOC

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

9. Switch off the entire system. The exact procedure is described in detail in chapter 9.2.2.
- Battery fuse switch to OFF
- DC switch of the Inverter to OFF
- AC fuse on the Grid and emergency power side to OFF

10. Installation of the new battery towers as described in chapter 7.1.1 and chapter 7.1.2.
11. Carry out DC cabling as described in Chapter 7.2.1and Chapter 7.2.2.
12. Wire the communication between the battery towers as described in chapter 6.3.9.
13. Everything can then be switched on again as described in chapter 9.2.1.

14. 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 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 connector 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 2 and 3 can be connected via pins 13/14 and 15/16 on the Harting connector.
2. For detailed information on connecting the Heat pump, please refer to the manufacturer’s installation instructions.

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 called a "power-to-heat" application.

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.

1. So that each phase of the Heating element can be controlled separately, each phase must be connected individually to a relay.
2. To do this, connect phase 1 (brown) to pin 11. Continue from pin 12 to the Heating element. Use pins 13/14 and 15/16 for phase 2 (black) and phase 3 (gray).
3. The relays with the Heating element must be pre-fused with an LS B10.
4. 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.
5. 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.

8.3. 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 referred to as a "power-to-heat" application.
When the capacity of the electrical storage unit is exhausted, self-generated energy must be fed into the public Grid at a low rate. In these cases, it often makes sense to use the surplus electricity to heat water (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 output of the installed Heating element.

1. 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.
2. Connect L1 to pin 11 via a fused LS B6. Route phase L1 from pin 12 to the external relay and connect to A1. A2 must be connected to the neutral conductor.
3. Proceed in the same way as step 2 with the other two phases. Connect K2 and K3 via pins 13/14 and 15/17.

4. As an alternative to L2/L3, L1 can of course also be looped through, or +. 5. Alternatively, control the contactors/relays with 24V. If a different voltage source is used, A2 must not be connected to N.

6. The voltage supply of the Heating element must then be connected to the switching contacts of the relays. If another voltage source is used, A2 must not be connected to N.
7. For detailed information on connecting the Heat pump, please refer to the manufacturer’s installation instructions.

8.4. 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.

1. The enable signal for starting the CHP unit can be connected via pins 11/12.
2. For detailed information on connecting the CHP unit, please refer to the manufacturer’s installation instructions.

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 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.

1. Instead of connecting the communication line of the Inverter directly to pin 1/2, as described in chapter 6.3.8, the communication line to the meter must be connected to pin 1/2.
2. white to 1; brown to 2

3. The connection to the Inverter is then established from the meter. This means that two wires must be connected to one connection on the meter.

white to 3

brown to 2

8.6. §14a 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.

1. The signal can be connected to pins 5 (C) and 8 (A) via the Harting connector (16-pin - A & C).
2. For detailed information on connecting the FNN control box, please refer to the manufacturer’s installation instructions.

9. Initial commissioning

9.1. Checking the installation, connections and cabling

Check the system as follows before initial commissioning:

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

1. fuse the EMS box (sub-distribution board, or socket outlet)
2. Fuse the Inverter. (sub-distribution, Grid and emergency power side)
3. If available, switch on the PV system with the DC switch on the inverter. (underside of the inverter)

4. securing the battery tower (front battery tower)
5. If there are several battery towers, all towers must be secured

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

8. When the LED bar starts to flash, the 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. Switch off

1. securing the battery tower (front battery tower)
2. If there are several battery towers, all towers must be secured.

3. If present, switch off the PV system with the DC switch on the Inverter.
4. Secure the Inverter. (sub-distribution, Grid and emergency power side).
5. Fuse the EMS box (sub-distribution board or socket outlet)

6. 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.
7. The Inverter remains on if one of the three energy sources is not switched off.
