components in detail

EPP 400 watt Hieff solar panel black

EPP solar premium PV modules have a power of 400Wp and one special high module efficiency of 21.23% offers a better energy yield than modules with lower efficiency, even in low light conditions.

The front screen made of tempered glass with anti-reflective coating and the robust black aluminum frame ensure the best stability, even with strong wind (up to 2400 Pa) and heavy snow loads (5400 Pa) .

Each monocrystalline silicon cell is covered with an ETFE film that protects it from dirt, grime and water. thanks to the Waterproof class IP68 This portable solar panel works safely in all weather conditions and is perfect for camping and rooftop use.

The innovative technology and the high resilience reliably increase performance and minimize losses due to shading.


Small inverter with high performance!
Microinverter for feeding into your home network. EPP/DEYE inverter is easy to set up and configure . Ideal for small solar systems, for example on balconies, garden houses, garages or shaded areas. Deye 300 has a single MPPT , which ensures that each PV module has the can achieve the highest power generation .

Smart monitoring:

Operate your inverter conveniently via APP!

Track your successes at any time! The integrated WLAN interface allows you to integrate this inverter into your network.

Access via the App SOLARMAN is possible with your smartphone or tablet. In addition, browser-based access is possible with your device.


  • Peak efficiency of 96.5%
  • Continuous performance monitoring via WiFi and app
  • Degree of protection IP67 - tightness against water and dust
  • Quick shutdown function
  • Integrated MPP tracking
  • Up to approx. 410Wp module power


The Hoymiles HM300 is the perfect microinverter for your balcony power station. The compact lightweight (only 1.98 kg including the 1.35 m AC cable) is suitable for solar power production with one solar panel to one Power of 410 watts peak. Just like all other Hoymiles microinverters, it is suitable for long running hours and wide PV module application, since its startup is very low (only 22V) and the DC input range of the operating voltage (16-60V) is extremely wide.


  • Easy installation with Plug & Play
  • High reliability, IP67 (NEMA 6) enclosure, 6000V surge protection
  • External antenna for stronger communication with DTU
  • peak efficiency of 96.70%;
  • Up to 410Wp module power
  • Minimizing the effects of eg shading, dust or aging by MPPT

Did you know that electricity costs in Germany increased by more than 73% since 2000? But what will happen in the future?

Many power plants will be closed in the next few years while demand from e-mobility increases.


frequently asked Questions

How does a balcony power plant work?

The balcony power plant system is a compact photovoltaic system. It consists of solar modules and a module inverter for feeding into your own electrical house supply network. Ideally, the module inverter is attached directly to the substructure of the solar module on the outside. The module is connected to the module inverter via standard plugs. Then the 230V output cable of the inverter is connected to any house socket. Complete.

Why should I buy a balcony power plant?

Because it produces part of the electricity required in the household and thus significantly reduces the total expenditure on electricity. In addition, exactly this proportion is not produced in a coal/gas or nuclear power plant in a way that is not harmful to the environment.

How much electricity does the balcony power plant produce?

This depends on the location of the plant. There are computer programs that have saved the empirical values ​​of the last few years for each region in Germany and use them to create a yield forecast with considerable accuracy.

For the Würzburg region, for example, a module with 400 Wp Solar power harvest of approx. 600+ kWh per year .

35 cents gross This module saves approx.

How do I see how much electricity is being produced?

You can purchase an energy cost meter for the socket from us.

Can I disconnect the system from the mains during operation?

Yes, that is possible without any problems. The balcony power plant can be safely disconnected from or connected to the grid at any time.

How is the connection made?

The balcony power plant system can be installed very easily and quickly by anyone with technical experience. No special tools are required for assembly. In some European countries, the balcony power plant system with a Schuko plug can be plugged directly into any socket. In Germany, a fixed connection is required. For simple and proper connection, we recommend using a Wieland power socket.

Do I need a separate balcony power plant for each phase?

No. Electricity meters with a backstop are netting. This means that the electricity generated on one phase is offset against the electricity consumed on another phase. If, for example, you have connected consumers with 1000 watts of power to phase 1 and produce 1000 watts with your balcony power plant on phase 3 of your electricity network, the electricity meter automatically offsets the phases with each other and shows no consumption in total. On the other hand, if you consume 1200 watts on one phase and generate 1000 watts on another phase, the electricity meter only counts the 200 watts that are more consumed. Due to the ver of the electricity meter, it is therefore irrelevant in which of the three phases in your home network you feed in and to which the consumers are connected.

Please note that the 0% tax exemption for photovoltaic items only applies to customers with private installations with a maximum output of up to 30,000 watts. If this does not apply to your order, you must inform us so that we can charge VAT at the rate of 19%.

Sales tax will no longer apply to deliveries of photovoltaic systems from January 1, 2023 if they are installed on or near a residential building (zero tax rate). The regulation applies to all components of a photovoltaic system, e.g. B. photovoltaic modules, inverters or battery storage.
