Balcony Solar Kit Flex 440 Wp – Envertech EVT800 – 600 W

With this Balcony Solar Kit with 440 Wp Generate your own solar power right on your balcony. Two monocrystalline, semi-flexible solar modules, each with a power output of 220 Wp, feed power into the Envertech EVT800 microinverter. This device converts the generated direct current into grid-compatible alternating current for household use.

The solar power is automatically used by the electrical appliances that are currently running. As a result, the refrigerator, router, lighting, chargers, and other appliances draw less energy from the public grid. If more electricity is generated than is needed at any given time, the surplus flows through the electricity meter into the distribution grid.

Each of the two Flex modules weighs only about 3.5 kg and features built-in mounting eyelets. This makes them particularly well-suited for compatible balcony railings where heavy glass modules or complex mounting systems are not an option.

Lightweight Flex Modules for the Balcony

The two semiflexible 220-Wp solar modules each measure 1100 × 1080 mm and are only about 3 mm thick without the junction box. Their light weight makes them easier to handle than conventional framed glass modules.

• 440 Wp total power consisting of two solar modules, each with a capacity of 220 Wp
• only about 3.5 kg per solar panel
• Twelve built-in eyelets per module for proper fastening
• MC4-compatible connectors and 4-mm² solar cables
• Compact dimensions for limited balcony space
• monocrystalline solar cells with a module efficiency of 20.18%

Semi-flexible solar modules are bendable, but cannot be folded or kinked at will. Installation, the mounting surface, and the permissible degree of bending must comply with the specifications in the module documentation. Point loads, sharp edges, and installations that are under constant tension must be avoided.

Envertech EVT800: Limited to 600 W for Switzerland

The Envertech EVT800 has two separate PV inputs, each with its own MPPT tracker. This allows each of the two solar modules to be connected individually to the microinverter. Variations in irradiance or partial shading of one module have a less significant impact on the other input than they would in a common series connection.

The EVT800 is designed to deliver a maximum AC output power of up to 800 W. However, the version intended for this Swiss balcony solar kit is Limited to a maximum AC output power of 600 W and thus takes into account the currently applicable Swiss power limit for plug-and-play photovoltaic systems.

The 600-W limit cannot be changed by the operator via the EnverView app, the monitoring system, or other device settings. Any unauthorized modification is prohibited and may compromise the compliance of the entire balcony solar kit.

Prepared for a possible future 800-W regulation

The Envertech EVT800's technical platform is already designed for up to 800 W. Should the permissible AC output power for plug-and-play photovoltaic systems in Switzerland be increased to 800 W in the future, the manufacturer can adapt the Swiss 600-W version accordingly.

Such a change does not occur automatically and is not intended by the operator. It may only be implemented once Swiss regulations permit it and an officially approved performance adjustment from the manufacturer or provider is available. The applicable requirements for conformity, connection, and registration must also be taken into account.

Wi-Fi Monitoring with EnverView

The Envertech EVT800 features built-in Wi-Fi and can be connected to the EnverView app or the Envertech Portal. This allows users to monitor, among other things, current power output, operating status, and energy generated.

To ensure stable data transmission, a sufficient Wi-Fi connection should be available at the installation site. The monitoring system is used for display and monitoring purposes. The 600 W limit specified for Switzerland cannot be changed by the operator through this system.

For which applications is this set suitable?

The Balcony Solar Kit Flex 440 Wp is designed for renters, condominium owners, and homeowners who want to generate grid-connected solar power at a suitable location. Typical applications include:

• Balconies with appropriate and sturdy railings
• Railings with secure mounting options
• Patios with railings and a suitable outdoor electrical outlet
• Apartments or single-family homes with basic appliances running during the day

This kit is a grid-connected, plug-and-play photovoltaic system. The Envertech microinverter requires an existing and suitable power grid. The kit is not intended to serve as a standalone power supply for a traditional off-grid or emergency power system.

What's Included

Installation and Commissioning

1. Check the location, railing construction, load-bearing capacity, wind load, and electrical outlet.
2. Securely fasten the flex modules according to the installation instructions, ensuring they are free of tension.
3. Install the Envertech microinverter in a suitable and adequately ventilated location.
4. Connect one solar module to each PV input on the microinverter.
5. Report the system, along with the declaration of conformity, to the relevant distribution system operator.
6. Connect the AC power cord to the designated Swiss outdoor outlet.
7. If necessary, set up Wi-Fi monitoring according to the Envertech instructions.

Reporting Requirements and Use in Switzerland

In Switzerland, plug-and-play photovoltaic systems must currently not exceed an AC output of 600 W per subscriber connection or electricity meter. The responsible distribution system operator must be notified in writing prior to commissioning. The declaration of conformity for the complete set must be submitted at that time.

Depending on the building and installation location, additional requirements may include the landlord’s consent, a resolution by the condominium owners’ association, or local building code regulations.

Should the permissible power limit in Switzerland be raised to 800 W in the future, the regulations published at that time will apply. Any modification to the EVT800 may therefore only be made after a corresponding change in the law and official approval by the manufacturer or supplier.

Solar Energy Yield and Self-Consumption

Actual energy output depends on location, orientation, tilt, shading, temperature, and mounting method. Even when mounted vertically, the system can cover part of the household’s base electricity load. An orientation that maximizes sunlight exposure with minimal shading improves potential energy output.

Solar power provides the greatest economic benefit when it is consumed directly in one's own household. Appliances with programmable timers should therefore be operated during sunny hours whenever possible.

Technical Specifications

Conclusion

The Balcony Solar Set Flex 440 Wp is a compact solution for suitable balcony railings where low weight and ease of use are important. The two semi-flexible modules together deliver 440 Wp, while the Envertech EVT800 supplies the generated solar power in a grid-compliant manner for direct personal use.

The Swiss version is currently limited to a maximum AC output power of 600 W.

With the included extension and connection cables, as well as the UV-resistant cable ties, the essential components for the intended balcony installation are already included.

Frequently Asked Questions About the Balcony Solar Kit Flex 440 Wp

• Why is the set called "600 W" even though the solar modules have a combined power output of 440 Wp?

  
  

  The 440 Wp refers to the rated power of the two solar modules under standardized test conditions. The 600 W indicates the maximum AC output power of the microinverter in this Swiss kit configuration. Therefore, a sustained output power of 600 W should not be expected with the included modules.

• Is the set prepared for a potential Swiss 800-W regulation?

  
  

  The Envertech EVT800 is designed to handle a maximum AC output power of up to 800 W. Should Switzerland permit 800 W for plug-and-play photovoltaic systems in the future, the manufacturer can adapt the Swiss 600-W version accordingly. There are no plans for the operator to activate the system independently.

• Does the set automatically produce 800 W after an 800-W approval?

  
  

  No. The two included solar modules have a combined rated power of 440 Wp. Adjusting the microinverter does not change the available module power. For an expansion, the electrical compatibility, the permissible module configuration, and the compliance of the complete set must be re-evaluated.

• Can I change the 600-W limit myself?

  
  

  No. The limit cannot be changed via the EnverView app, the monitoring system, or other user settings. Any subsequent change may only be made after a corresponding amendment to Swiss regulations and with an officially approved update from the manufacturer or provider.

• What types of balcony railings is this set suitable for?

  
  

  This set is suitable for railings where the Flex modules can be securely fastened in accordance with the installation instructions so that they are tension-free and wind-resistant. Dimensions, load capacity, railing design, and wind load must be checked on a case-by-case basis before purchase.

• Does the facility have to be registered in Switzerland?

  
  

  Yes. The relevant distribution system operator must be notified in writing before the system is put into operation. In this regard, the Declaration of Conformity for the Complete Set submit. For rental properties, the landlord's or property management's consent is also required.

• What happens to unused solar power?

  
  

  Solar power is first used by household appliances that are running at the same time. Any surplus that is not consumed immediately flows through the electricity meter into the public grid. The relevant grid operator determines whether and under what conditions this electricity is compensated.

• Can the set be operated without connecting to the public power grid?

  
  

  No. The Envertech microinverter is designed for grid-connected operation and requires an existing power grid. The kit is not a standalone off-grid or emergency power system.

• How can self-consumption be improved?

  
  

  You'll get the most benefit when electricity consumption and solar production coincide. Whenever possible, run your washing machine, dishwasher, chargers, and other controllable appliances during the sunny hours of the day.
