Product details

Product Overview

Preparation
Requirements for the operation of a photovoltaic system

• Permission from the owner or owners’ association if you are not the owner yourself
• Wieland socket (recommendation), permanent connection or Schuko socket
• RCD in the fuse box (standard nowadays)
• Socket, better protected outdoors
• Electricity meter with backstop or bidirectional meter

ATTENTION!
The following requirements must be met to operate a photovoltaic system.

• You must register your photovoltaic system with your responsible grid operator.
• In addition, a report must be submitted to the responsible authority (Market Master Data Register (MaStR)).
• You must have ensured that an appropriate and sufficiently dimensioned feed-in socket is already available.
• Meter replacement required: A bi-directional meter must be present or depending on what your electricity provider specifies. Simple electricity meters are often not sufficient.
• If necessary, the consent of the landlord is required.
• If you are unsure, please have the local conditions checked, if necessary, or contact your network operator for information.

Connecting the micro inverter
The micro inverter is already pre-installed on a solar module in this set It may only be necessary to connect the solar modules (DC) to the micro inverter. On the AC side, only the connection with the enclosed connection cable must be made. A Wieland plug connection is recommended here according to VDE. A Schuko plug connection with a Schuko socket is also possible.

CAUTION
Observe all local regulations and restrictions during installation.

The external protective grounding conductor is connected to the protective grounding conductor terminal of the micro inverter via AC connection. When connecting, connect the AC terminal first to ensure the grounding of the microinverter. Then connect the DC terminals. When disconnecting, disconnect the AC first by opening the branch circuit breaker but keeping the protective grounding conductor in the branch circuit breaker connected to the microinverter. Then disconnect the DC inputs.

• Do not, under any circumstances, connect the DC input if the AC connection is not connected.
• Install disconnect devices on the AC side of the microinverter.
• It is strongly recommended to install surge protectors in the appropriate meter box.
• You should not use an AC residual current device to protect the corresponding circuit to the micro-inverter, even if it is an outdoor circuit. None of the small residual current devices (5~30 mA) are designed for regeneration and will be damaged if regeneration occurs. The same is true for AC arc fault circuit breakers. They are not evaluated for regenerative power and could be damaged if regenerated with the output of a solar micro inverter.

Connect the solar panels (DC connection)
Connect the solar panel’s DC cables to the DC input side of the microinverter.

The 600W micro inverter provides two pairs of MC4 connectors for two solar panels. Simply connect the DC connection cables of the micro inverter to the matching counterpart of the solar panel. When doing so, plug the pair of connectors together until you hear a “click” sound. The connectors of some solar panels have the polarity (+, -) printed on them, which is valid for the panels. The DC cable of the micro inverter with the plus marking (+) is connected to the – pole of the panel, the negative marked cable (-) to the + pole. Make sure that the polarity is correct.

Note: When plugging in the DC cables, if the AC cable is already plugged in, the micro inverter LED should immediately flash green and start synchronizing with the grid within 2 minutes. If the AC cable is not plugged in, the red LED will flash continuously and repeat this until the AC cable is plugged in (see chapter LED Status).

Connecting the micro inverter to the AC grid (AC connection)
WARNING: A maximum 1x 600W may be connected to an EU / 50Hz / 230V installation with 16A automatic circuit breaker.
The connection to the mains is made with a suitable power cable. Only use 3-core cables that are also approved for outdoor installation and have a conductor cross-section adapted to the amperage (preferably 1.5mm² or 4mm²).
Fasten the connection cables to the mounting rail using UV-stable cable ties in such  a way that the cables are protected from rain and sun and, in particular, the plug connections cannot lie in a puddle of water. To connect the micro inverter and the connection cable, the pre-assembled AC plug-in system in combination with an AC cable and assembled Betteri IP68 connection socket or the AC string input/output can be used, depending on the delivery variant. To mount a Wieland connector, the pre-assembled Betteri IP68 connector system must be removed.

Note: Other plug connections/systems may be possible, provided they are suitable for outdoor use and the current levels involved.

Mounting

Observe the following instructions for the corresponding installation.

General hints

• Before you start mounting, check the solar module, the inverter, and all cables for visual damage.
• Do not stand on the module or the module frame. To prevent grease stains on the module, avoid contact with your hands on the glass surface and ideally wear work gloves.
• Place the solar module face down on a clean, flat, soft surface.
• Write down the model and serial number of the components [inverter, solar module(s)] and keep the numbers. In the event of a defect, we will need the numbers for unique identification.

Balcony : The solar module is only suitable for installation up to a height of 4m (upper edge of the module), provided that there is also no public traffic below the module.

Flat roof (bitumen roof)

• The statics of the roof for the photovoltaic system must be checked by the customer. The photovoltaic system can be installed up to a roof height of 9m, a sea level of max. 350 m and a roof pitch of 45°.
• We recommend a distance of 1.25 m to firewalls of adjacent buildings (e.g. row houses). For more detailed requirements for your federal state, please refer to your state building code (LBO).
• Make sure that national and site-specific building regulations, occupational safety and accident prevention regulations, standards and environmental protection regulations are observed.

Weight the module mount evenly

• The solar module (up to 19kg) should be positioned at ground level or centered on a flat roof.
• Suitable is a bracket for mounting on bitumen, or concrete, in the garden on the lawn or terrace.
• The weighting is calculated according to the terrain IV (urban area), where at least 15% of the area is covered with buildings, the average height of which exceeds 15m, and may differ for other heights or terrain structures.
• In case of installation on a flat roof, the top edge of the building should be lower than 15m and the photovoltaic system should be at least 1.25m away from the neighbor’s roof surface. The maximum slope of the ground may be 5°.
• One concrete slab should weigh 9kg.
• Check whether the statics of the installation site are suitable for the photovoltaic system. Technaxx Germany does not assume any liability for the suitability of your installation site.

Facade

• For the mounting you need your own dowels and screws. Since every wall is different.
• Up to a height (upper edge of the module) of 4m the glass-foil module can be used, as long as you cannot step directly under the module.

First commissioning
After mechanical and electrical installation of the solar power system, you can put the system into operation. There should be enough sunshine for this. The solar panels need to produce at least a start voltage of 22V.

Initial state:

1. The micro inverter is connected to the solar panels
2. The microinverter is connected to the house mains via a Wieland plug(recommended) or Schuko plug.
3. The cables are fixed and protected from rain and sunlight
4. The feed line is connected to the mains via a circuit breaker

Proceed as follows:

1. Turn on the circuit breaker and any other switches that may be present.
2. Switch on the main AC switch.
3. The unit LED should begin flashing green after you turn on the AC circuit breaker. See chapter LED status for more information.
4. The micro inverter starts feeding (grid synchronization) within 2 minutes if there is sufficient solar radiation. The status LED indicates the basic function. You can check the feed-in power with a suitable power socket energy meter (needs to be waterproof for outside use!).
5. If you have installed a feed-in meter, you can also use it to check the current feed-in power or energy.

Note: When AC power is applied but the micro inverter is not started, approximately 0.2W of power can be measured for each micro inverter using a power meter. This power is reactive power, not consumption from the utility grid.

WiFi-Stick installation (DTU TX-247)

1. Solar panels and microinverters should be already installed and connected to the house grid.
2. Find best location for DTU. The maximum communication distance between the DTU and the microinverter is 150 m, maximum communication distance between the DTU and the router is 10m in open space. Walls, roofs, or other obstacles in between will affect the signal and reduce the communication distance in actual installations.
3. Connect the DTU to the adapter and plug it into the wall socket, like beside.
4. Once the DTU powers on, the red, green, and blue lights will flash in sequence for one second each for 30 seconds.

LED status
The LED of each microinverter provides information about the current status. All micro inverters draw their supply voltage from the DC connector/solar panels.

St atus during power-up
The green LED will flash fast a few times. The switch-on process usually takes up to 2 minutes. The following LED status can occur:

DC connection voltage lower 22V

| è no grid feed
Flashing fast green (1s):| AC connection &

DC connection voltage over 22V

| è grid feed
No LED Flashing/LED off:| No   DC   connection/solar   panels connected| è no grid feed

Status after the switch-on process

• A fast green flashing LED indicates normal status and an active feed into the grid. If the LED remains flashing red after 3 minutes, this indicates an error with solar panel voltage that is too low (below 22V) or a missing AC voltage.
• The micro inverter can only start feeding (again) after the cause of the error has been eliminated. The reason for this error could be a faulty solar panel connection / AC connection or the connected grid exceeds / falls below the voltage/frequency range of the microinverter. If the LED shows no function or remains OFF, the most common cause is that there is no connection to the solar panel or the solar panel voltage is far below the start voltage.

Troubleshooting

Maintenance work and troubleshooting on the microinverter may only be carried out by qualified personnel. Modifications to the micro-inverter are generally prohibited. The micro inverter is potted, the electronics cannot be repaired. The TX-204 micro inverter draws its supply voltage from the DC side. To restart the microinverter, the solar panels must be disconnected from the micro inverter. The start-up process usually takes place within 2 minutes. For troubleshooting purposes, perform the following steps in the order listed:

1. Check that all AC fuses are turned ON.

2. Check all connection cables for external damage.

3. Check all AC side connections for damage or connection errors.

4. Measure at the connection points. The applied mains voltage must not exceed or fall below the AC voltage range of 180-275V.

5. Restart the micro-inverter by disconnecting and reconnecting the DC power / solar panels. A normal start-up process should be indicated by a green LED (see LED status).
   CAUTION: Never disconnect the DC cables while the micro inverter is generating power.

6. Measure the voltage of the solar panel to the micro-inverter with a suitable multi-meter. The required starting voltage of the microinverter is above DC22V.

7. Check the MC4 connectors of the micro inverter and solar panel(s). Damaged DC connections must be replaced.

8. If necessary, check with your grid operator whether the grid frequency matches the frequency range of the microinverter.
   CAUTION!

   • Do not attempt to repair the microinverter.
   • If the above steps do not solve the problem, contact our support or an electrician.
   • The AC connection on the microinverter cannot be replaced/repaired. If the cable has been damaged, the device should be disposed of.
   • Unless otherwise specified, maintenance work must be carried out with the equipment disconnected from the mains (mains switch open) and the solar panels covered, or insulated.
   • Do not use rags or corrosive products for cleaning that could corrode parts of the equipment or cause electrostatic charges.
   • Avoid temporary repairs. All repairs should be made only with original spare parts.
   • Each micro-inverter should be protected by a circuit breaker, but central disconnect protection is not required unless specified by national standards, or by the responsible network operator.

Appendix
Determining the line reserve
The PI Photovoltaic Institute Berlin in cooperation with the German Society for Solar Energy (DGS), and the University of Applied Sciences (HTW) Berlin has worked out in a study that it is possible to feed in up to 2.6 amps (approx. 630 W, equivalent to 2 solar modules) with plug-in solar devices in every household with circuit breakers without any safety concerns, without having to make any changes to the house electrics. However, there may be a deviation from the applicable standard for line loading. We have described how to comply with the requirements of the standard and how to test the line in this appendix. If mini solar systems feed into the existing final circuit, the current load on individual cable sections may exceed the designed standard size. To prevent overloading of the cables in the household, they are protected by a line circuit breaker (LSS). This switches off automatically as soon as an overload occurs. As a rule, several sockets and consumers are protected by a common line protection. Due to the additional power of the mini solar system, the currents from the utility grid and the mini solar system can now add up. However, the currents are not detected by the line circuit breaker, so theoretically an overload can occur. You can use the following formula to determine whether the existing line with your circuit breaker is sufficiently dimensioned:

Iz indicates the current carrying capacity of the line, which should be greater than the sum of the rated current of the protective device (circuit breaker in amperes) and the generating equipment (power in amperes). Both Iz and Ig can be found in the following table for the example application below.

• Iz = In + Ig
• Iz Permissible current carrying capacity of the line
• In Rated current of the protective device (circuit breaker)
• Ig rated current of the power generation system

Load capacity of copper lines

Photovoltaic system| one solar module| two solar modules| up to 3 × 115W| from 4 × 115W
max. current load in amperes| 1.3| 2.6| 1.3| 2.6

The example from the table is based on two loaded copper lines with a nominal cross-section of 1.5mm2, which reflects the line in a typical German household. In the case of a larger cross-section or a different cable type, the permissible current-carrying capacity is different, so this must be considered separately, by DIN VDE 0298-4.

Determination of the line reserve
If the cable is a copper cable with a core cross-section of 3×1.5mm2, then the cable is designed for a continuous load of 16.5A (in thermally insulated walls at 25°C). The free capacity is the difference between the line with 16.5A and the circuit breaker with 16A. The free capacity is therefore 0.5A in thermally insulated walls. If the solar power exceeds the current of 0.5A, then the circuit breaker should be replaced with a smaller one to comply with the requirements of the DIN VDE 2948-4 standard. By exchanging the fuse for a smaller 13A fuse, 13A can now still be drawn from the power grid, resulting in free capacity for the power line with a difference of 3.5A. The power of the mini solar system could therefore be up to 805W. In the example (right half of the picture), the power of the mini solar system is 2.6A/600W, which complies with the permissible load.

Further safety instructions

• Only connect the mini solar system to a permanently connected socket, never to a multiple socket.
• If you still have older screw fuses installed, it is mandatory to replace them from 16A to the next smaller fuse.
