• MC4 solar cable extension, 10 m: This extension cable is the longest option and offers you all the advantages of the 2 m and 5 m versions.

Important notesConnecting modules in parallel increases the current. This can lead to exceeding the maximum permissible input current of the inverter and destroying it. Before connecting solar modules in parallel, please check that the permissible values ​​are observed.

Connect solar cables correctly

When connecting solar cables for balcony power plants and solar installations, it is crucial to always use the correct cable types and connect them properly to the solar panels and inverters of your system! Ensure that all cables are securely fastened and the connectors are locked in place to prevent electrical losses, hazards, and moisture ingress. The cables should be neatly routed and protected against mechanical damage to ensure long-term reliability.

Using solar cables to connect balcony power plants

In our Download In this section you will find many different instructions that can help you with the assembly, installation, and wiring of our products. For example, operating instructions for all Hoymiles inverters used in our balcony power plants are available there. 

With the help of these instructions, you can easily and quickly attach our solar cables to your module yourself. We would like to briefly explain in general terms how a balcony power plant is installed and how the individual cables are connected. Please contact us if you have any questions.

Assembly and connection instructions for balcony power plants and solar cables:

1. Mount solar panels on a bracketFirst, connect the solar panel to the selected mounting bracket. Additional instructions for connecting the panel and bracket are included. Please follow these instructions.
2. Connecting solar panels to an inverterNext, each solar panel is individually wired to the inverter of its respective set. Each panel is connected to a separate pair of cables on the inverter. If the panels are not close enough together for the panel's connection cables to reach, MC4 extension cables will be needed. You should hear a short click when connecting the plugs – this is the only way to ensure they are properly engaged.
3. Connect the inverter to the mains power cable.Connect the power cable to the AC port of the inverter. Some inverter models have an additional AC port, allowing multiple inverters to be connected in series. Attach the end cap to this remaining port. This prevents moisture from entering and damaging the inverter. Ensure that the power cable and end cap click into place and are securely connected.
   
4. Connection to the power gridA Schuko plug can now be easily connected to the household mains by plugging it into a suitable socket. If a Wieland socket is to be used, the Wieland plug must be inserted into it, and further installation should be left to a qualified electrician. 
5. Wait for synchronization to complete.Within 15 minutes, your balcony power plant should change from a red flashing light to a green signal. This signal indicates that the power plant is now connected to the house's electrical grid and can feed energy into the system. The inverter is powered by the solar panels. If you perform the installation in low light conditions, the energy generated by the solar panels may not be sufficient to activate the micro-inverter. In this case, wait until the next day and try again in brighter light.

Important tips and instructions to consider during installation and wiring:

• The inverter must be installed away from flammable or highly combustible surfaces.
• The inverter should not be mounted in direct sunlight and should be protected from rain or snow.
• Attach all solar cables without pulling on them.
• Seal all unused plugs with end caps.
• Do not connect the power supplies to multiple sockets.
• Do not mount the solar panels more than 4 m high and ensure that no people can remain underneath them.
• A distance of 125 cm to the neighboring building must be strictly maintained during roof installation in order to comply with fire protection regulations.
• Check the structural integrity of the installation site and stop the installation process if the balcony power plant does not function as desired.
