How does grid feed-in work?

Grid feed-in is a process in which the electricity generated is fed directly from the solar module and the appropriate inverter into the public power grid. Ideally, the inverter is installed near the solar modules and connected to the solar module using the solar connector. Regardless of the size of the system, it is necessary to register the solar system with the market master data register in accordance with legal requirements.

The complete system includes:

• 10x Luxen Solar 450W Bifacial Solar Module TopCon Luxneri Series N5 Full Black
• 1x Growatt MIC 3000TL-X string inverter PV 3000W 1-phase
• 1x Growatt SPM-E electricity meter 1-phase 100A smart meter
• 1x Growatt Shine-WiLan-X2 data logger
• 3x MC4 connector pairs - socket + plug 4-6mm² Type 4 PV-KBT4/6I

Why use a string inverter: The performance of solar modules varies depending on temperature, irradiation, and shading, which can lead to mismatching losses. These losses occur when the performance of one panel in a string is lower than the others, resulting in lower power production for the entire string. A string inverter can reduce these losses.
Maximum Power Point Tracking: Maximum Power Point Tracking technology generates the best possible yield from a solar system. The MPPT of the MIC inverter determines the optimal ratio between voltage and current throughout the day, depending on the solar radiation and the temperature of the solar modules. The large MPPT voltage range allows a large number of solar modules to be connected, enabling efficient energy yield. The advantage of this is most noticeable when the sky is partially overcast and the light intensity is constantly changing.
Flexible and easy installation: Thanks to its compact dimensions and low weight, the inverter is quick and easy to install and connect. The integrated MC4 connections also allow the solar supply to be connected to the inverter in a matter of moments. The numerous protective functions ensure safe and smooth operation of the solar system.
