Offgridtec 890w Growatt neo 800m-x Trina Vertex s+ Dual Glass Mini-PV solaranlage

The 890w balcony power plant from Offgridtec is based on two high-quality, monocrystalline 445w Vertex-s solar modules from Trina solarand the 1-phase neo 800m-x 800w micro inverter from Growattthe system also includes a suitable ac connection cable for the micro inverter and two mc-4 connection cables for the solar modules. The balcony power plants from Offgridtec offer a practical solution for generating part of the electricity required for the household and thus significantly reducing the costs for overall electricity consumption.

how does a balcony power station work?

The Offgridtec balcony power station is a space-saving solarasystem consisting of two solar modules and a matching Growatt micro inverter to feed the electricity generated into the household power grid. Ideally, the inverter is attached directly to the substructure of the solar module and connected to the solar connector on the module. The ac cable is connected via the battery connection of the inverter and routed directly to the appropriate socket. no special setting is required to use the solar power generated in the home's power grid. if power from other sources is available in the home, this is used preferentially and supplemented by grid power if necessary.

The complete balcony power station system includes:

• 2x Trina solar Vertex s+ 445w dual glass solar module
• 1x Growatt neo 800m-x 800w micro inverter
• 2x Offgridtec 3m mc-4 connection cable
• 1x Growatt 5m neo 800-m-x ac connection cable Micro inverter

Trina solar Vertex s+ 445w solar module

The Trina solar Vertex s+ is an effective solar module with an output of 445w that uses monocrystalline TOPCon cells and dual-glass technology. Thanks to the multi-busbar technology, it offers improved absorption, low series resistance, improved current dissipation and reliability. It is certified for extreme wind and snow loads of 5400 - 4000 Pa and has highly transparent, 1.6 mm thick glass with anti-reflective coating. The frame is made of a 30 mm wide, anodized aluminium alloy.

Features

• Multi-busbar technology
• Dual glass design
• High-density cell connection technology
• N-type i-TOPCon cell technology
• very low degradation
• High efficiency of 22.3%
• Manufacturer product guarantee: 25 years
• Universal solution for residential and C and I roofs

N-TOPCon cell technology

The advanced TOPCon technology (Tunnel Oxide Passivated Contact) is a further development of PERC technology and aims to increase the efficiency of solar cells. The solar modules are provided with an ultra-thin oxide layer and a subsequent conductive layer, which leads to a so-called passivated contact. As a result, the performance of the solar cell is improved in low light conditions, leading to higher annual energy production.

Balcony power stations in Germany

There is currently no law or ordinance in Germany that regulates the generation of solar power for purely domestic use. The maximum limit of 600w ac PV power is a reserve value which, according to the current VDE standard, can be fed into an existing socket circuit of a house without overloading it. Nothing is described for independent circuits without additional load. Every electrical installation should be VDE-compliant. However, the operation of a balcony power station via a standard Schuko socket is not prohibited. Registration with the Federal Network Agency is mandatory. However, there are no known cases of fines for non-registration of balcony power stations or insurmountable problems with network operators. Compliance with and implementation of standards and obligations is the responsibility of the system operator. A great deal of technical and legal information can already be found on relevant websites.
