The system includes four Full Black Luxen Solar panels, each delivering 450W and featuring cutting-edge technologies, a MIC-1500TL-X string inverter from Growatt including the Shine-WiLan-X2 control unit, and the single-phase SPM-E energy meter, which is used for grid export limitation and self-consumption monitoring. The set also includes a 30m solar cable and a 10m high-end rubber cable from Lapp-Kabel, as well as 3 MC4 connectors. The modules are designed to be installed directly side by side.

How does a balcony power plant work?

The 1800W balcony power plant from Offgridtec is a space-saving solar system consisting of four solar modules and a suitable Growatt micro inverter to feed the generated electricity into the household power grid. The inverter should ideally be mounted near the solar panel and connected using the solar connector on the module. No special configuration is required to use the generated solar power in the home power network. If electricity is available from other sources in the house, it is used first and supplemented by grid power if necessary.

Installation note: For this non-plug-in-ready device or component, connection and installation must only be carried out by a qualified electrician. Please follow the user manual!

LECO N-TOPCon Cell Technology

The advanced TOPCon technology (Tunnel Oxide Passivated Contact) is an evolution of the PERC technology and aims to increase the efficiency of solar cells. It is complemented by Low Efficiency Cell Optimization (LECO), which further improves overall cell performance, especially under suboptimal lighting conditions. During manufacturing, an ultra-thin oxide layer and a conductive layer are applied to create a passivated contact. This improves the cell's performance in low-light environments and contributes to higher annual energy output.

Additionally, the combination of TOPCon and bifacial technology allows for even greater efficiency, as the cells can capture 15% more reflected light. These synergistic effects result in significantly increased energy yields, making these solar cells an outstanding choice for modern photovoltaic applications.

Half-Cut Technology

In half-cell technology (also called “half-cut”), conventional silicon cells are split in half using a laser. These half cells are then centrally connected in parallel, which reduces resistance losses and increases the performance of the solar panel.

Bifacial Cells

Bifacial modules offer a major advantage through their transparent backsides and special cell technology—they also utilize reflected light. This significantly increases energy yield, making them a particularly efficient choice for your solar system.

Why a String Inverter?

Solar panel performance varies due to temperature, irradiation, and shading, leading to so-called mismatch losses. These occur when one panel’s performance drops and brings down the output of the entire string. A string inverter can minimize these losses.
Maximum Power Point Tracking: MPPT technology ensures optimal output from your PV system throughout the day by adjusting the voltage and current based on sunlight and temperature. The wide MPPT voltage range allows a variety of solar panels to be connected, ensuring efficient energy harvesting. This is especially useful in partly cloudy conditions.
Flexible and easy installation: Thanks to its compact size and light weight, the inverter is quick and easy to install. The integrated MC4 connectors make it easy to connect your solar supply to the inverter. The numerous protection features ensure safe and smooth system operation.
